Most often, when designing big halls, call center interiors and auditoriums, soundproofing and acoustics are ignored. A large portion of the budget is kept for the furnishings and designing of the room as well as other aspects, there is little consideration for the acoustics in auditorium. It is not a wise idea to ignore the auditorium acoustics architectural design and rather should be taken care of and incorporated when the building is getting made. |
When preparing a good acoustic auditorium, the first aspect to keep in mind is the kind of performances that are going to take place there. These can be high powered electric or natural acoustic or even both. Well, a cookie cutter approach is not going to work here. Moreover a well planned auditorium acoustics design that worked a couple of years ago will not function well acoustically and can get overwhelmed with today’s high-powered line arrays. There can be annoying slap-back interferences within the existing space.
The next factor that impacts the acoustics of auditorium is the noise or sound problem. Is the sound leaving the auditorium or entering it to disturb people in the building or those outside it. Higher-pitched noise carrying lower energy content will be less intense and can be easily controlled with sound proof auditorium wall tiles and mass loaded vinyl layers. The lower frequency sounds carry more power and longer wavelengths. This is the reason why the neighbors around will perceive a louder sound. The treatment lies in implementing solutions at the stage of construction where it is easy to work on the walls and ceiling.
The number of people sitting in the hall too impacts the acoustics auditorium and performance. Solutions are sought by adding sound absorption to room surfaces, generally on the walls and the ceiling. A thicker material that is also fluffy and porous is able to achieve better sound absorption. People count in this cover-up for auditorium acoustics too and the acoustics change when auditorium is filled with people.
The good looks and symmetry in a hall often lead to lower quality sounds due to the cohesion of wavelengths, canceling or reinforcing at the same frequencies. Thus symmetry in the auditorium will not produce good acoustics necessarily. Keep your priorities right , right from the start Are you looking for perfect designing or perfect acoustics? If acoustical function is not an equal consideration, one can focus on the design and looks .
Acoustic tiles for call centers for sound absorption placed anywhere to minimize the noise and reverberation time. However, this alone will not take care of the complete problems and other acoustic issues. Those annoying reflections are more easily heard once the reverb gets reduced. They keep bouncing off the rear wall out of time sequence and are the most troublesome. This can not only confuse the performers but also be annoying to the audience who are listening.
Keep the above aspect sin kind when designing a hall or an auditorium. The discussion of noise pollution and noise reduction is a deep one and covers many aspects and relates to many issues.
