C Weighting A standard weighting of the audible frequencies used for the
measurement of Peak Sound Pressure level
CE Marking A label used to show that the Sound Level Meter conforms to the
specification of a European Directive
dB(A) Decibels A weighted
dB(C) Decibels C weighted
Decibel (dB) The unit of sound level and noise exposure measurement
Fast Time Weighting A standard time weighting applied by the Sound Level Meter
IEC 61252:1993 The International Standard for Personal Sound Exposure Meters
(PSEM)
Integrating Averaging
Sound Level Meter
A Sound Level Meter which accumulates the total sound energy
over a measurement period and calculates an average

Equivalent continuous sound pressure level. A measure of the
average sound pressure level during a period of time, t, in dB
Overload The input to the Sound Level Meter is too high for the current
measurement range. Change the range
Peak The maximum value reached by the sound pressure at any
instant during a measurement period (in dB usually with C
