Frequently Asked Questions
1 What is a Sound Level Meter?
A Sound Level Meter is an apparatus designed to measure sound pressure levels in decibels (dB).
2 How does Sound Level Meter work?
It works with the help of a microphone that detects sound waves and converts them into electrical signals which are processed and displayed as dB readings on the meter.
3 Why is calibration important in case of Sound Level Meter?
It is essential to check and recalibrate the apparatus with a reference calibrator in order to ensure reliable measurements.
4 Can Sound Level Meter be used for hearing protection recommendations?
It is used to assess noise exposure and helps in determining whether a hearing protection is needed or not.
5 How does a Sound Level Meter help in noise pollution control?
By measuring the noise levels over time and identifying sources of excessive sound, it helps in quantifying noise pollution.
6 What is the difference between a Sound Level Meter and a Noise Dosimeter?
Sound Level Meter is used for measuring specific noise levels over a short period whereas Noise Dosimeter is used to continuously monitor the exposure to noise over an extended period.
7 Can Sound Level Meter be used in environmental studies?
It is commonly used in environmental studies to assess noise pollution and determine its impact on wildlife habitats.
8 Can Sound Level Meter be used to measure human voice levels?
It is used to measure the intensity of speech or human voices.
9 Can Sound Level Meter be used to monitor the effectiveness of noise barriers?
It is used to measure noise levels before and after installing a noise barrier.
10 Can Sound Level Meter be used in industrial setting?
It is used in factories and industrial settings in order to monitor noise levels and ensure their compliance with safety regulations.
