A. INTRODUCTION Noise pollution disorders the balance or activities in mankind or habitat. The source of most outdoor noise worldwide is mainly machinery, vehicular transportation, aircraft, and trains. Poor urban planning tends to worsen noise pollution, since adjacent industrial and residential structures can result in noise pollution in the residential areas.
Since over exposure of noise pollution may produce stress or hypertension for the person, they decided to find ways to make their respective place more peaceful by making their residential structures reinforcements to absorb incoming sound waves. They do this to avoid certain risks concerning health. This was called “Soundproofing”.
Soundproofing is the method of reducing sound pressure with respect to a specified sound source and receptor. It may be approached by sound blocking or sound absorption. Both have different purposes, either to reduce sound entering or reducing the sound bouncing inside a room.
