Most sound meters incorporate a processing network that assigns relative importance to low-, middle-, and high-frequency signals. By comparing differently weighted measurements, you can isolate the source of problem sounds.
"A" Weighting attenuates the lower frequencies to approximate the response of the human ear, which is most sensitive to frequencies between 3000 and 4000 Hz.
"B" Weighting gives decibel readings of combined high- and middle-frequency signals. Use in conjunction with A weighting to isolate sounds that are causing a problem.
"C" Weighting reads all frequencies the same but gives a better response to higher frequencies than A or B weighting. Use to pinpoint problems when A or B weighted scale readings are very high.The CEL-240 series is a completely new range of sound level meters that combine the power of Digital Signal Processing (DSP) technology and simplicity and low cost of a traditional analog instrument. The meter has a low and high measurement range that covers a full 70dB on each setting and include A and C frequency scales and slow, fast and impulse time responses. A non-decaying maximum hold feature on every display captures and displays the highest sound pressure level of any noise until reset by the user. The optional software package is ideal for datalogging in spreadsheet format file for analyzing measurement data further.

What's Included:
Kits include one sound level meter, acoustic calibrator, foam windscreen, carrying case, calibration certificate, and three AA batteries.
