:: Glossary of Terms ::

Sampling speed
The sampling speed determines the amount of data per second received. Larger values give a more exact calculation.

Gain
Gain is a factor by which the input signal is amplified.

Low pass filter
A low-pass filter is a filter that passes low-frequency signals and attenuates signals with frequencies higher than the reference frequency.

High pass filter
A high-pass filter is a filter that passes high-frequency signals and attenuates signals with frequencies lower than the reference frequency.

Band pass filter
A band-pass filter is a filter that passes frequencies within a bandwidth around the reference frequency and attenuates frequencies outside that range.

dB(A)
Describes the relative loudness perceived by the human ear.

Leq
Leq is the Sound Pressure Level in dB, equivalent to the total Sound Energy over a given period of time.

LAeq
Presser level measurement parameter. Full form of LAeq is [Equivalent continuous A-weighted sound pressure level].
