Effect of vibration
For mechanical vibration with an acceleration of 1 m/s² vertically to the membrane of the microphone for the
frequencies 31,5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 630 Hz, 800 Hz and 1000 Hz increases the low level
of the linear operation range to 70 dB for t
he frequency weighting “A”.
For mechanical vibration with an acceleration of 1 m/s² parallel to the membrane of the microphone for the
frequencies 31,5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 630 Hz, 800 Hz and 1000 Hz increases the low level
of the linear operation range to 80 dB for the frequency weighting "A".

microphone: 160 dB.
ST 104B and SV 104BIS frequency characteristics
The instrument should be mounted so that the microphone diaphragm is perpendicular to the direction of the
sound wave.
