(Greek: akoustikos, to hear, hearing; to listen, listening)
To avoid having acoustic trauma, people should wear protective ear plugs or ear-cover protectors to minimize damage to their ears when using loud equipment.
Everyone should be aware of risks of acoustic traumas that are connected with such activities as shooting guns, using chain saws, lawn mowers, driving motorcycles, or when using snowmobiles.
Another way of avoiding acoustic trauma is to refrain from listening to loud music for long periods of time.
Acoustic trauma can occur as a result of an individual's occupation, such as rock musicians, construction workers, airline ground crew members, or by using earphones and headphones, etc. with the volume turned up too much.
2. Concerning sounds that are made by musical instruments and voices: Margaret loves to listen to acoustical folk music.
One music hall had several acoustical clouds suspended from the ceiling, however the architect forgot to take into consideration that heat from the audience and the performers could send the acoustical clouds spinning around over the heads of the audience and therefore the architect had to come up with a better solution.
The normal areas of acoustical engineering include, among others: architectural and musical acoustics, noise and vibration control, underwater acoustics, ultrasonics, communication engineering, shock and vibration engineering, and instrumentation engineering.
- Architectural and musical acoustics or environments involving sounds.
- Noise and vibration control or keeping sounds within acceptable limits.
- Underwater acoustics or sonar engineering oceans.
- Ultrasonics or ultra-high-frequency sounds and vibrations.
- Communication engineering or the transmissions of spoken information.
- Shock and vibration engineering is a part of mechanical and structural engineering.
- Instrumentation engineering relates to all of the preceding issues, such as the design and applications of sensors for sounds and vibrations, of sounds and vibration generators, of recording systems, and of data analysis equipment.
After her university training, Alice was able to get a job working for a hearing aid company, working as an acoustician who was developing more efficient hearing devices.
New York mayor started campaign to crack down on noise
- In the year 2002, the mayor of New York, Michael Bloomberg, went after the noise makers.
- He announced a program to tackle the quality-of-life problem most vexing to New York residents: barking dogs, screeching car alarms, music blaring from cars, and drunken bar patrons who share their feelings with everyone on the block at 3 a.m.
- The initiative, known as "Operation Silent Night", was the city's most aggressive attack on noise since 1994.
- The operation was set up to focus on twenty-four neighborhoods that had been identified as among the noisiest, based on calls to the city's quality-of-life hot line.
- Tickets ranging from $5 to $25,000 for businesses with excessive noise complaints were to be issued: arrests, in the most extreme cases, might be made, and cars with blaring alarms were to be towed away.
2. In physics, the study of sounds, including their productions, transmissions, and general effects: The laboratory for acoustics at the university was outfitted with the latest technology and equipment for analyzing audible and inaudible vibrations.
Acoustics often determines how well sounds can be heard in the structural features of a room, a hall, an auditorium, etc.3. In architecture:
- The sum of the qualities, as absence of echo or reverberation, that determine the value of a room or auditorium with respect to distinct hearing: The famous symphony conductor tested the acoustics of the newly build performance hall and announced that the sound was very good.
- The science of planning and building an enclosure so that sound will be perfectly transmitted to the people who are in it: The newly hired engineer for the architecture firm had her engineering degree in acoustics and seemed the ideal candidate to work on the new performance hall.
