Abstract

A PC-based wireless instrument for monitoring noise pollution was designed, implemented, and calibrated. A low-powered portable FM transmitter with a FET microphone and preamplifier was used to transmit the audio signal of the noise being measured to an FM receiver interfaced to a personal computer.
Noise pollution in the highway of Los Baños was monitored for 3 days at 10-minute intervals from approximately 8 AM to 7 PM. Results showed that the early start of the day has the lowest measured Sound Pressure Levels (SPL) followed by an increase in SPL readings. The Sound Pressure Levels (SPL) of the noise measured by the instrument was compared to the standard value, and were found to be 87.69 – 99.41% accurate. The study showed that the average noise pollution at the site exceeds the recommended Threshold Limit Values for noise.
