Sound Proofing

The Problem

Unwanted noise lowers the quality of life. There have been several ways that noise can affect human health, comfort and efficiency.
 
Insomnia is a common result for light sleepers. For mild cases, it strain one’s sense as a results of slow but persistent noise i.e. moving traffic, animals, neighbour noise; this causes frustration, difficulty in sleeping or concentration thus affecting work performance the next day.
 
Sudden and loud noise produces a startle effect i.e. slamming of door, honk, shouts; which can be more harmful than a continuous noise.
 
In the long run, It also brings about adverse health issues such as chronic headache, hypertension, undesirable change in gastro intestinal activities behaviour and emotional stress.

Serangoon is noisiest part of Singapore

A total of 18,768 sound measurements were recorded over a 21/12-month period in a new study on noisy by NUS audiologist William Hal Martin and graduate student Diong Huey Ting.

Accoeding to the data, the noisiest parts of Singapore (based on planning zones) are:

The Solution

 
 

UNDERSTANDING NOISE

Noise is measured by Decibel (dB). A normal talking conversation is around 60Db as compared to a vacuum cleaner that is measured at approximately 85Db.
The increased noise (dB) results in an increased amount of stress for the brain, and muscle (energy) to fend off the noise while multi-tasking to continue with our own activities.
The pain threshold for human ears starts at about 125 dB where one will experience a sharp physical pain in the ear however prolonged lowered dB noise can also have the same effect.

SOUND TRANSMISSION CLASS

STC (Sound Transmission Class) is an integer rating of how well a partition (medium) attenuates airborne sound.
Let’s say we have a 100dB source from one side of the wall. And the reading on the other side of the wall is 75dB.
The transmission loss will be 25dB. Therefore, a higher rated STC wall or window will help to reduce noise infiltration more effectively.
