TERMINOLOGY
1.
Sensitivity (dBV) - Sensitivity is a measure of the microphone output response to the acoustic pressure of a 1kHz 94dB SPL
(1Pa RMS) sine wave.
2.
Total Harmonic Distortion (%) – THD is the ratio of the RMS sum of the harmonic distortion products in the specified bandwidth
(see note below) relative to the amplitude of the fundamental (ie. test frequency) output.
3.
Signal-to-Noise Ratio (dB) – SNR is a measure of the difference in level between the output response of a 1kHz 94dB SPL
sine wave and the idle noise output.
4.
Dynamic Range (dB) – DR is the ratio of the 1% THD microphone output level (in response to a sine wave input) and the idle
noise output level.
5.
All performance measurements are carried out within a 20Hz to 20kHz bandwidth and, where noted, an A-weighted filter.
Failure to use these filters will result in higher THD and lower SNR values than are found in the Acoustic and Electrical
Characteristics. The low pass filter removes out of band noise.
