The Problem

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

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.
