Arrangement of a proper speaker system of suitable configuration is the basic requirement of a theatre acoustics arrangement. The acoustic treatment consists of the utilization of sound reflecting, absorbing materials for the room. Most rooms have little or no absorptive materials. This would result in a reflection of sound leading to echoes from speakers. This superimposition of sound needs to be addressed for home theatre acoustics.
Acoustics
Generally, the sound source would-be speakers. Based on the size of the room and purpose Acoustics is planned. In general, the purpose of design could be a meeting hall, theatre, music concert, or lecture hall. Based on the functionality the reverberation time is modified. Sound absorbing materials and sound-reflecting materials are arranged. Sound absorption and reflection are achieved
by the use of materials. These materials are of two types. They include natural materials that are available naturally. Examples include jute bag, coconut fibres while synthetic materials include rubber, felt, cardboard, glass, and fibre wool.
In acoustics, the design of structure plays a vital role. Designs that have huge doors, windows, ceiling height support acoustic function in the room while materials like interior works that include glazing, smooth flooring, wall contours both concave and convex type alter acoustics.

Acoustic arrangement for Homes
For residential designs, simple arrangements/modifications help in Acoustics. For example, the speakers are to be placed at least 2 feet away from the walls/partitions. The furniture arrangement is to be planned accordingly. This helps in achieving mid-range and mid-bass response that influences the type of sound effect.
Living room Acoustic arrangement –Location of speakers
In the living room in case you propose to have a home theatre, it is to be ensured that the speakers are not placed parallel to the television as there would be an influence of sound and the richness of the music might get diluted.
Room Acoustic-Position of Speakers
Home theatre Acoustic constitute of detachable speakers apart from the standard built-in speakers. For pleasant sound, it is suggested the position of the speaker is to be aligned such that they fall in line with the ear position. Normally based on seating arrangement the height and position of the speaker are to aligned so they sound the best.
Frequently Asked Questions
1)Why is Acoustic important ?
Acoustics deals with sound reflection and absorption. To have adequate clarity of the conversation or music inside a structure, the design should favour acoustics.
2)How is Acoustics modified inside a room ?
Acoustics is basically to change/alter reflection/ absorption of sound. This is achieved by using both synthetic/natural materials inside the room in form of modifications. They include the use of internal partition, false roofing, and glazing.
3)How does Acoustics affect industrial establishments ?
High-intensity sound damages the hearing process in humans. So the emitted noise is to be dampened by the use of acoustic techniques. Use of acoustic materials in flooring, walls, ceiling
4) How does speaker position in room influence acoustics?
The sound from loudspeakers in an room arrangement don’t arrive at our ear as one uniform source. There is a time lag owing to positioning .Multidirectional sound waves reflect at surfaces of the room from room’s walls, floor, windows and ceiling. These reflections have a lag owing to sound velocity and arrive slightly after direct sound from the speakers. This influences the auditory experience.
5)Are Acoustic modification / alteration expensive ?
Acoustic materials are of different type based on the nature of application .Hence parameters like room size , design ,volume play a critical role in modifying the acoustics .Latest technology has materials that could be used without altering or demolishing the structure to incorporate acoustic balance .
6)Where are Acoustic modification done in Industries ?
Any moving component produces a vibration resulting in noise .When the noise level is beyond human tolerance , care is to be taken to modify the intensity of sound by acoustic procedures to prevent damage to human ear.
