subject: Sound Insulation An Effective Way To Control Noise Pollution [print this page] Any sound that is unpleasant to the ears, whether it is of human, animal or machine-created, is termed as noise. Alarms, barking dogs, audio entertainment systems, loud people, fireworks and emergency sirens may at some time disrupt the normal flow of human or animal life, and may lead to noise pollution.
Thought of noisy neighbors or children playing loud musical instruments while you are asleep, harsh sound of domestic appliances, moving traffic, or maybe your desire to install a home theatre while your neighbor doesn't approve of it due to the presence of thin walls, are enough reasons to give you sleepless nights. Therefore, there is a dire need to control unwanted noise, and here sound insulation systems come into existence.
In order to ensure total comfort and privacy, sound insulation has become vital in industrial, commercial and educational environments. Sound Insulation is an effective way to reduce sound transmission between separating floors, which facilitates noise reduction & noise absorption. Usage of intervening objects in the path of transmitting sound waves to block their passage is known as noise reduction, while transforming or suppressing different kinds of sound waves like reflection, reverberation, echoes and resonance is called noise absorption.
Sound insulation is provided by using ducts that can be installed using blown in insulation or may be fitted into the structures. Fiberglass is a commonly used soundproofing material used in duct insulation for minimizing the cross transmission of sound across crawl spaces, garages, attics or unfinished basements. Duct insulation helps in absorbing the sound waves that otherwise traverse freely in the atmosphere, be it residential or office buildings, institutions, marine vessels or trains.
Use of insulation not only reduces the noise levels considerably, but also lessens the echo in big halls and minimizes the sound emitting from various types of machines, equipment, instruments etc. Moreover, acoustic control provides better working conditions, as it suppresses unpleasant sounds that may have environmental or heath impact.
