Acoustic Insulation And its Applications

In India there is so much variations in temperature in different parts from south to north and east to west so there is always requirement of Acoustic insulation in every building as walls in general are built with elements heavier than the partitions between different dwellings, they can be considered as already suitable for obtaining an evaluation index of soundproofing power higher.

It will therefore be sufficient to fill the inter space with self-supporting panels. As regards with other construction types and in different climatic conditions, there will have to be as many evaluations concerning the new values of the transmittance coefficient.

Acoustic Insulation India also known as Sound Proofing which defines as any means of reducing the intensity of sound. Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. This is required for reducing Sound Abuse. This is mainly for providing comforts and cozy working atmosphere. The main application is on Buildings, Malls, Theaters, Hotels, Studios and Hospitals where simultaneous activities are going on.

There Are Several Basic Approaches to Reducing Sound Through Acoustic Insulation:

• Using damping structures such as sound baffles

• Increasing the distance between source and receivers 

• Using active anti noise sound generators.

• Using noise barriers to reflect or absorb the energy of the sound waves 

Two distinct soundproofing problems may need to be considered when designing acoustic treatments - to improve the sound within a room and reduce sound leakage from adjacent rooms or outdoors.

Acoustic Insulation India can be increased by using double walls. However, this can be done in the case of lightweight walls, as the heavier (and more insulating) the wall, is, the more difficult it will be to increase the insulation. The solution is to build two single walls and space them a certain distance apart. This assembly will provide greater insulation than a single wall of equivalent mass, and represents a mass-spring-mass system.

Soundproofing can suppress unwanted indirect sound waves such as reflections that cause echoes and resonances that cause reverberation. Soundproofing can reduce the transmission of unwanted direct sound waves from the source to an involuntary listener through the use of distance and intervening objects in the sound path.

The insulation can be increased by fitting a flexible, absorbent material, such as rock wool, in the chamber, so that the spring effect is increased and the stationary waves are eliminated. Another effective method, particularly for very rigid walls, is to use the diaphragm effect. This consists of filling the cavity with a material comprising a thin membrane with very low effect.

Acoustic Insulation is Used in Many Ways, The Applications Includes:

• Acoustic insulation is used in ceilings, floors and refurbishing walls.

• Acoustic insulation is used in lightweight metal or wooden, roofs and floors.

• Acoustic insulation includes in drainpipes, conducts, engines.

• Damping of metallic structures.

• Acoustic insulation is used for gypsum board partitions and ceilings, metal panels.

• Sealing of joints and overlaps.

• Acoustic insulation is used for Cavity walls.
