Sound Level Meters

Sound level meters respond to fluctuations in air pressure caused by sound waves and are sometime referred to as Sound Pressure Level (SPL) Meters. ATP Stocks a selection of sound level indicators, high-performance meters that conform to IEC 61672-1:2013 Class 1 and Class 2, and Dosemeters. Whether you need a simple indicator or a high-spec meter we aim to source the most cost-effective solutions available on the market. Learn more

Some Useful Sound Level Meter Articles

Sound Level Meter Terminology

Time Weightings
A standardised delay in recording changes to sound level
Slow	A slower response time to changes in sound. - 1 second
Fast	A fast response time to changes in sound - 125ms
Impulse	A quick response time designed to measure bursts of sound
Frequency Weightings
A change to the emphasis to certain frequencies to reflect different perceptions of sound.
'A' Weighting	Standard weighting of audible frequencies designed to reflect the response of the human ear.
'C' Weighting	Standard weighting used for Peak sound pressure measurements
'Z' Weighting	A flat frequency response of 8Hz to 20kHz ±1.5dB

Note: Time weightings and Frequency weightings are often indicated as part of the measurement parameter. Leq would be respresented as LAeq or LCeq with the A or C representing the Frequency weighting. LCFmax represents the maximum sound level at the C Frequency weighting and Fast Time weighting, LASMax would respresent maximum sound level at the A Frequency weighting and Slow Time Weighting.

Sound Level Measurement Parameters

Term	Description
db(A) or dBA	Decibels 'A' Weighted
db(C) or dBC	Decibels 'C' Weighted
db(Z) or dBZ	Decibels 'Z' Weighted
Lp	Sound Presure Level
Leq	Equivalent Continuous Sound Level
Lmax	Maximum Sound Level
Lmin	Minimum Sound Level
Peak	Highest peak of the pressure wave with no time constant applied - Not to be confused with Lmax
LEp'd	Daily Personal noise Exposure
LEp'w	Weekly personal noise exposure'
LE	Leq normalised to 1 second
