Acoustical, Noise & Sound Insulation
Description
Literally, insulation is the act of separating an object from others by non conductors so as to avoid transfer of heat, electricity, sound, etc. Acoustical insulations are insulations designed for reducing the transmission of sound through walls, floors and ceilings, thus preventing echo or reverberation.
Common approaches to acoustic insulations are:
Various acoustic materials are wool, glass, vinyl acoustic barrier, acoustic tiles, acoustic panels and acoustic foam.
Noise insulations are designed for reducing transmission of undesirable noise such as those from automobiles and from areas of heavy vehicular traffic.
Approaches to noise insulation are:
Noise reduction
Noise absorption
Noise control products are noise mufflers, industrial silencers and industrial baffles.
Sound insulations means reducing sound pressure with respect to specified sound source and receptor.
Basic approaches to reduce sound are:
Increasing the distance between source and receiver
Using noise barriers to block or absorb the energy of sound waves
Using damping structure such as sound baffles
Using active antinoise sound generators
The different kinds of sound insulation materials are resilient bars, bricks, rubber, cotton and vibration pads.
Features
Applications
Acoustic insulations are helpful in community halls, galleries, restaurants, conference suites, studios and interview rooms. Sound insulations are employed in dwelling places such as duplexes and apartment buildings, recording studios and are ideal for any public areas like shopping malls, clubs and auditoriums. Sound reducing ply woods are commonly employed in trains, bus floors and apartments. Noise insulation is ideal in areas of close proximities to railways and industries.
