93-423: After almost five decades of service to Bowling Green State University, it became apparent that Anderson Arena was at the end of its useful life due to its limited accommodations. There were only two restrooms in the entire arena and poor acoustics for concerts , and it also lacked air conditioning . The most glaring factor that demanded replacement of Anderson Arena was that it was severely out of compliance with

186-590: A Bachelor's degree or higher qualification. Some possess a degree in acoustics, while others enter the discipline via studies in fields such as physics or engineering . Much work in acoustics requires a good grounding in Mathematics and science . Many acoustic scientists work in research and development. Some conduct basic research to advance our knowledge of the perception (e.g. hearing , psychoacoustics or neurophysiology ) of speech , music and noise . Other acoustic scientists advance understanding of how sound

279-516: A media timeout between innings, and to time warmup periods for relief pitchers coming out of the bullpen . For cricket a scoreboard will as a minimum display the batting team's score, wickets fallen, the opposition's totals. Most county-standard scoreboards will also display each batsman's score, overs remaining, extras, the bowlers currently on and details of the last wicket to fall. Australian state scoreboards will usually contain more detailed information. An ice hockey scoreboard will at

372-727: A baseball against the panel. Examples of this type of scoreboard display are seen in Milwaukee 's Miller Park , Rogers Centre in Toronto , New Yankee Stadium in The Bronx , and Kauffman Stadium in Kansas City. In all three cases, the walls display the current game state of out-of-town games (often down to pitch count for the current at-bat and runners on base), statistics for the current batter or pitcher, and promotional messages. Another display has been added to minor and major league stadiums through

465-405: A branch of acoustics. Frequencies above and below the audible range are called " ultrasonic " and " infrasonic ", respectively. In the 6th century BC, the ancient Greek philosopher Pythagoras wanted to know why some combinations of musical sounds seemed more beautiful than others, and he found answers in terms of numerical ratios representing the harmonic overtone series on a string. He

558-686: A building from earthquakes, or measuring how structure-borne sound moves through buildings. Ultrasonics deals with sounds at frequencies too high to be heard by humans. Specialisms include medical ultrasonics (including medical ultrasonography), sonochemistry , ultrasonic testing , material characterisation and underwater acoustics ( sonar ). Underwater acoustics is the scientific study of natural and man-made sounds underwater. Applications include sonar to locate submarines , underwater communication by whales , climate change monitoring by measuring sea temperatures acoustically, sonic weapons , and marine bioacoustics. Scoreboard A scoreboard

651-562: A definite mathematical structure. The wave equation emerged in a number of contexts, including the propagation of sound in air. In the nineteenth century the major figures of mathematical acoustics were Helmholtz in Germany, who consolidated the field of physiological acoustics, and Lord Rayleigh in England, who combined the previous knowledge with his own copious contributions to the field in his monumental work The Theory of Sound (1877). Also in

744-420: A game settings as the bylaws of the major basketball sanctioning bodies and many of the high school athletic bodies decree that both scores must display in the same color; the rule came into effect in 1994 after Spectrum Scoreboards introduced an earlier version of the concept. This is used almost exclusively in recreation leagues. For baseball the scoreboard will at the minimum show both team scores, as well as

837-416: A multi-purpose gridiron/soccer venue type scoreboard where various statistics are shown. Such may include either total fouls, corner kicks, shots on goal, or other important statistics for spectators to learn their team's overall performance. Similar to baseball , a softball scoreboard will at the minimum show both team scores and the current inning. In addition, the number of balls, strikes and outs, and

930-465: A quarter, but they are not used in larger venues. In those cases, the referee or public address announcer denotes the termination of a quarter vocally via the PA system; formerly quarter ends were denoted with the firing of a starting pistol in the era before digital timing. A basketball scoreboard will at the minimum display the time left in the period and both teams' scores. The last minute of each quarter

1023-400: A result of varying auditory stimulus which can in turn affect the way one thinks, feels, or even behaves. This correlation can be viewed in normal, everyday situations in which listening to an upbeat or uptempo song can cause one's foot to start tapping or a slower song can leave one feeling calm and serene. In a deeper biological look at the phenomenon of psychoacoustics, it was discovered that

1116-405: A rock concert. The central stage in the acoustical process is wave propagation. This falls within the domain of physical acoustics. In fluids , sound propagates primarily as a pressure wave . In solids, mechanical waves can take many forms including longitudinal waves , transverse waves and surface waves . Acoustics looks first at the pressure levels and frequencies in the sound wave and how

1209-603: A rotating basis. There is also a designated area within the arena for cataloging and storing items not currently on display. Before the facilities at the Stroh Center, almost all memorabilia and artifacts related to Bowling Green athletics since the university's opening in 1910 had been stored in boxes in a small room just off the lobby of Anderson Arena in Memorial Hall and voluntarily collected and stored by former Bowling Green men's soccer and lacrosse coach Mickey Cochrane, who

1302-468: A separate possession arrow display at half-court; not used in the NBA). College basketball scoreboards include shot clocks and the number of time-outs left for each team, with some high school state athletics bodies also beginning to adopt shot clocks to remove end of game stalling . Larger scoreboards include statistics on the players in the game. Basketball scoreboards must include a horn or buzzer to signal

1395-456: A sound wave to or from an electric signal. The most widely used transduction principles are electromagnetism , electrostatics and piezoelectricity . The transducers in most common loudspeakers (e.g. woofers and tweeters ), are electromagnetic devices that generate waves using a suspended diaphragm driven by an electromagnetic voice coil , sending off pressure waves. Electret microphones and condenser microphones employ electrostatics—as

1488-463: A trend in the 1990s, and after a controversial series of calls during the 2002 NBA Playoffs , the NBA instituted a new game shot clock rule in 2002, requiring specific visibility of the game- and shot-clock time for instant-replay purposes. FIBA installed a similar three-sided rule in 2004. The rule was further changed in 2005 by permitting a new Daktronics see-through model (one on top of the basket, one on

1581-603: A very good expression of the nature of wave motion. On Things Heard , generally ascribed to Strato of Lampsacus , states that the pitch is related to the frequency of vibrations of the air and to the speed of sound. In about 20 BC, the Roman architect and engineer Vitruvius wrote a treatise on the acoustic properties of theaters including discussion of interference, echoes, and reverberation—the beginnings of architectural acoustics . In Book V of his De architectura ( The Ten Books of Architecture ) Vitruvius describes sound as

1674-438: A wave comparable to a water wave extended to three dimensions, which, when interrupted by obstructions, would flow back and break up following waves. He described the ascending seats in ancient theaters as designed to prevent this deterioration of sound and also recommended bronze vessels (echea) of appropriate sizes be placed in theaters to resonate with the fourth, fifth and so on, up to the double octave, in order to resonate with

1767-465: A way of echolocation in the caves. In archaeology, acoustic sounds and rituals directly correlate as specific sounds were meant to bring ritual participants closer to a spiritual awakening. Parallels can also be drawn between cave wall paintings and the acoustic properties of the cave; they are both dynamic. Because archaeoacoustics is a fairly new archaeological subject, acoustic sound is still being tested in these prehistoric sites today. Aeroacoustics

1860-450: Is a large board for publicly displaying the score in a game. Most levels of sport from high school and above use at least one scoreboard for keeping score, measuring time, and displaying statistics. Scoreboards in the past used a mechanical clock and numeral cards to display the score. When a point was made, a person would put the appropriate digits on a hook. Most modern scoreboards use electromechanical or electronic means of displaying

1953-440: Is a variable message display next to each field event area that displays the standings and who is up next. Other indicators may show track side wind speed. In some settings where a track surrounds an athletic field, a track and field scoreboard may be combined within the football scoreboards. An association football scoreboard usually shows the score for the home and away team, as well as the current match time. A board displaying

2046-464: Is a well accepted overview of the various fields in acoustics. The word "acoustic" is derived from the Greek word ἀκουστικός ( akoustikos ), meaning "of or for hearing, ready to hear" and that from ἀκουστός ( akoustos ), "heard, audible", which in turn derives from the verb ἀκούω( akouo ), "I hear". The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics and later

2139-503: Is affected as it moves through environments, e.g. underwater acoustics , architectural acoustics or structural acoustics . Other areas of work are listed under subdisciplines below. Acoustic scientists work in government, university and private industry laboratories. Many go on to work in Acoustical Engineering . Some positions, such as Faculty (academic staff) require a Doctor of Philosophy . Archaeoacoustics , also known as

2232-418: Is called frequency shift keying (FSK). Two radio frequencies represent binary 0 and 1. Radio transmission such as FSK sends data digitally. Until recently radio transmission was subject to short range and interference by other radio sources. A fairly recent technology called spread spectrum permits much more robust radio control of scoreboards. Spread spectrum , like the name implies, distributes

2325-416: Is concerned with noise and vibration caused by railways, road traffic, aircraft, industrial equipment and recreational activities. The main aim of these studies is to reduce levels of environmental noise and vibration. Research work now also has a focus on the positive use of sound in urban environments: soundscapes and tranquility . Musical acoustics is the study of the physics of acoustic instruments;

2418-408: Is defined by ANSI/ASA S1.1-2013 as "(a) Science of sound , including its production, transmission, and effects, including biological and psychological effects. (b) Those qualities of a room that, together, determine its character with respect to auditory effects." The study of acoustics revolves around the generation, propagation and reception of mechanical waves and vibrations. The steps shown in

2511-430: Is how our ears interpret sound. What we experience as "higher pitched" or "lower pitched" sounds are pressure vibrations having a higher or lower number of cycles per second. In a common technique of acoustic measurement, acoustic signals are sampled in time, and then presented in more meaningful forms such as octave bands or time frequency plots. Both of these popular methods are used to analyze sound and better understand

2604-726: Is namesake for the Mickey Cochrane Stadium which serves as the home of the Bowling Green Falcons men's and women's soccer teams. On February 8, 2020, the Hall of Fame was dedicated as the Schmidthorst Heritage Hall following renovations, adding items from the Cochrane Cunningham Archives to the hall. Harold Anderson , former Bowling Green men's basketball coach and athletic director and namesake for

2697-411: Is reputed to have observed that when the lengths of vibrating strings are expressible as ratios of integers (e.g. 2 to 3, 3 to 4), the tones produced will be harmonious, and the smaller the integers the more harmonious the sounds. For example, a string of a certain length would sound particularly harmonious with a string of twice the length (other factors being equal). In modern parlance, if a string sounds

2790-416: Is the electronic manipulation of acoustic signals. Applications include: active noise control ; design for hearing aids or cochlear implants ; echo cancellation ; music information retrieval , and perceptual coding (e.g. MP3 or Opus ). Architectural acoustics (also known as building acoustics) involves the scientific understanding of how to achieve good sound within a building. It typically involves

2883-431: Is the scientific study of the hearing and calls of animal calls, as well as how animals are affected by the acoustic and sounds of their habitat.

2976-413: Is the study of noise generated by air movement, for instance via turbulence, and the movement of sound through the fluid air. This knowledge was applied in the 1920s and '30s to detect aircraft before radar was invented and is applied in acoustical engineering to study how to quieten aircraft . Aeroacoustics is important for understanding how wind musical instruments work. Acoustic signal processing

3069-461: Is usually displayed with tenths of a second, which is required in FIBA, NBA (since 1989), and NCAA (since 2001). Most high school scoreboards also include a display of the number of team fouls, the number of the last player to commit a personal foul (with the total number of personal fouls for that player), the period, and indicators of which team is in the team foul penalty situation, and possession (with

3162-460: Is usually small, it is still noticeable to the human ear. The smallest sound that a person can hear, known as the threshold of hearing , is nine orders of magnitude smaller than the ambient pressure. The loudness of these disturbances is related to the sound pressure level (SPL) which is measured on a logarithmic scale in decibels. Physicists and acoustic engineers tend to discuss sound pressure levels in terms of frequencies, partly because this

Higher levels will also include play clocks and the number of time outs left for each team. American football scoreboards may include a horn to signal the end of

3534-555: The speed of sound in air were carried out successfully between 1630 and 1680 by a number of investigators, prominently Mersenne. Meanwhile, Newton (1642–1727) derived the relationship for wave velocity in solids, a cornerstone of physical acoustics ( Principia , 1687). Substantial progress in acoustics, resting on firmer mathematical and physical concepts, was made during the eighteenth century by Euler (1707–1783), Lagrange (1736–1813), and d'Alembert (1717–1783). During this era, continuum physics, or field theory, began to receive

3627-840: The 1980s most electronic scoreboards were electro-mechanical. They contained relays or stepping switches controlling digits consisting of incandescent light bulbs . Beginning in the 1980s, advances in solid state electronics permitted major improvements in scoreboard technology. High power semiconductors such as thyristors and transistors replaced mechanical relays , light-emitting diodes first replaced light bulbs for indoor scoreboards and then, as their brightness increased, outdoor scoreboards. Light-emitting diodes last many times as long as light bulbs , are not subject to breakage, and are much more efficient at converting electrical energy to light. The newest light emitting diodes can last up to 100,000 hours before having to be replaced. Advances in large-scale integrated circuits permitted

3720-415: The 19th century, Wheatstone, Ohm, and Henry developed the analogy between electricity and acoustics.

For instance, a home run may be depicted by an animation of a ball flying out to space. These animations are usually high in detail and are customized for

4278-461: The above diagram can be found in any acoustical event or process. There are many kinds of cause, both natural and volitional. There are many kinds of transduction process that convert energy from some other form into sonic energy, producing a sound wave. There is one fundamental equation that describes sound wave propagation, the acoustic wave equation , but the phenomena that emerge from it are varied and often complex. The wave carries energy throughout

4371-594: The acoustic phenomenon. The entire spectrum can be divided into three sections: audio, ultrasonic, and infrasonic. The audio range falls between 20 Hz and 20,000 Hz. This range is important because its frequencies can be detected by the human ear. This range has a number of applications, including speech communication and music. The ultrasonic range refers to the very high frequencies: 20,000 Hz and higher. This range has shorter wavelengths which allow better resolution in imaging technologies. Medical applications such as ultrasonography and elastography rely on

4464-429: The archaeology of sound, is one of the only ways to experience the past with senses other than our eyes. Archaeoacoustics is studied by testing the acoustic properties of prehistoric sites, including caves.

As plans for

5022-493: The central nervous system is activated by basic acoustical characteristics of music. By observing how the central nervous system, which includes the brain and spine, is influenced by acoustics, the pathway in which acoustic affects the mind, and essentially the body, is evident. Acousticians study the production, processing and perception of speech. Speech recognition and Speech synthesis are two important areas of speech processing using computers. The subject also overlaps with

5115-438: The complete laws of vibrating strings (completing what Pythagoras and Pythagoreans had started 2000 years earlier). Galileo wrote "Waves are produced by the vibrations of a sonorous body, which spread through the air, bringing to the tympanum of the ear a stimulus which the mind interprets as sound", a remarkable statement that points to the beginnings of physiological and psychological acoustics. Experimental measurements of

5208-420: The current inning . In addition the number of balls, strikes and outs is represented by digits or individual lights. Larger scoreboards offer an inning -by-inning breakdown of the scores, hits, errors, pitch count and the time of day, along with pitch clocks for leagues which mandate that rule. There may also be another display either separate or combined with the scoreboard listing the radar gun reading of

5301-435: The current stoppage time is usually held up by one of the match officials towards the end of the first and second half. The same board is also used to denote the jersey numbers of players coming in and leaving the game during a substitution , with the substitute's number appearing in green, while the leaving player is denoted in red. Some amateur and youth levels will have the clock count down. Some American venues will use

5394-536: The disciplines of physics, physiology , psychology , and linguistics . Structural acoustics is the study of motions and interactions of mechanical systems with their environments and the methods of their measurement, analysis, and control. There are several sub-disciplines found within this regime: Applications might include: ground vibrations from railways; vibration isolation to reduce vibration in operating theatres; studying how vibration can damage health ( vibration white finger ); vibration control to protect

The final effect may be purely physical or it may reach far into the biological or volitional domains. The five basic steps are found equally well whether we are talking about an earthquake , a submarine using sonar to locate its foe, or a band playing in

7254-435: The relationship between acoustics and cognition , or more commonly known as psychoacoustics , in which what one hears is a combination of perception and biological aspects. The information intercepted by the passage of sound waves through the ear is understood and interpreted through the brain, emphasizing the connection between the mind and acoustics. Psychological changes have been seen as brain waves slow down or speed up as

7347-413: The running order of the race, and number of laps completed. Some more complex boards scroll statistics such as average speed, laps behind, and timing reports. All codes of rugby football have a game clock, the number of tries, penalties, field goals and conversions listed. In track and field there is usually an elapsed time display. Sometimes the team scores are displayed. Often in higher levels there

7440-411: The same position as shots on goal in hockey games. In some university arenas, the scorer's table, which has traditionally been used for displaying physically scrolling advertising boards along its face, may also feature either a traditional mechanical scoreboard, or a scoreboard display within a LED display on the front of the table which also functions with virtual scrolling advertisements. Since 1991,

7533-445: The science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, craft, science and technology have provoked one another to advance the whole, as in many other fields of knowledge. Robert Bruce Lindsay 's "Wheel of Acoustics"

7626-520: The score. In these, digits are often composed of large dot-matrix or seven-segment displays made of incandescent bulbs , light-emitting diodes , or electromechanical flip segments. An official or neutral person will operate the scoreboard, using a control panel . In both the United States and Canadian football codes, the minimum details displayed are the time and score of both teams. A typical high school scoreboard will additionally display

7719-456: The scoreboard, Capturion manufactured the scorer's tables and press row, which also feature the company's latest technology. There also is a 3-by-30-foot (0.91 by 9.14 m) "ribbon board" on the east end of the court with a variety of other scoreboards. The Stroh Center also holds a prominently placed Hall of Fame to commemorate the history of athletics at Bowling Green State University that includes exhibits and display cases that hold items on

7812-496: The scoreboard, include Fenway Park in Boston and Wrigley Field in Chicago . In some stadiums since 2005, LED boards which are the full height of the outfield wall have been installed to either replace a manual scoreboard or enhance an existing wall, are considered in play, and are durably constructed to withstand the impacts of fielders colliding with the wall, along with the impact of

7905-412: The signal over a wide portion of the radio spectrum . This helps the signal resist interference which is usually confined to a narrow frequency band . Within the last few years most major league, professional and major college venues also include smaller displays featuring closed captioning of announcements from the public address system and advertisements displayed on the scoreboards to comply with

7998-512: The site's topping off occurred during a ceremony on May 3, 2010. In July 2008, the university announced that a 2-ton, 23-foot (7.0 m) falcon statue would be installed at the entrance of the new arena. The statue was a gift from North Carolina philanthropist, Irwin Belk , and cost $ 100,000. The statue was designed by the Jon Hair Studio of Fine Art near Cornelius, North Carolina and will be

8091-444: The sound wave strikes the microphone's diaphragm, it moves and induces a voltage change. The ultrasonic systems used in medical ultrasonography employ piezoelectric transducers. These are made from special ceramics in which mechanical vibrations and electrical fields are interlinked through a property of the material itself. An acoustician is an expert in the science of sound. There are many types of acoustician, but they usually have

8184-468: The study of speech intelligibility, speech privacy, music quality, and vibration reduction in the built environment. Commonly studied environments are hospitals, classrooms, dwellings, performance venues, recording and broadcasting studios. Focus considerations include room acoustics, airborne and impact transmission in building structures, airborne and structure-borne noise control, noise control of building systems and electroacoustic systems. Bioacoustics

8277-456: The time varying pressure level and frequency profiles which give a specific acoustic signal its defining character. A transducer is a device for converting one form of energy into another. In an electroacoustic context, this means converting sound energy into electrical energy (or vice versa). Electroacoustic transducers include loudspeakers , microphones , particle velocity sensors, hydrophones and sonar projectors. These devices convert

8370-420: The ultrasonic frequency range. On the other end of the spectrum, the lowest frequencies are known as the infrasonic range. These frequencies can be used to study geological phenomena such as earthquakes. Analytic instruments such as the spectrum analyzer facilitate visualization and measurement of acoustic signals and their properties. The spectrogram produced by such an instrument is a graphical display of

8463-466: The vote and approved of the future fee with 2,630 students in favor, while 1,182 were opposed. Seven sites around the campus were under consideration for the construction of the Stroh Center, including the adjacent parking lot next to Memorial Hall, which houses Anderson Arena and the intramural fields between Doyt Perry Stadium and the Kreischer residence halls. The university ultimately decided to build

8556-416: The wave interacts with the environment. This interaction can be described as either a diffraction , interference or a reflection or a mix of the three. If several media are present, a refraction can also occur. Transduction processes are also of special importance to acoustics. In fluids such as air and water, sound waves propagate as disturbances in the ambient pressure level. While this disturbance

8649-646: Was paid for with a $ 1.7 million donation from Allen and Carol Schmidthorst, while the court for the gym was paid for with a $ 1 million donation from Bowling Green alumnus Larry Miles. The auxiliary practice gym built with the combined $ 2.7 million helps the men's and women's basketball teams avoid scheduling conflicts with the arena, an amenity that was not available at the Anderson Arena. The arena also includes four visiting team locker rooms that can accommodate multiple teams that allow it to support events such as high school basketball tournaments. The main video board at
