Sound Sensor

The Sound sensor BT80i consists of a
microphone followed by an internal amplifier.
It measures variations in air pressure
caused by sound waves. Because of the high
sensitivity, the sensor is very much suited to
detect pressure pulses. The dB-calibration in
the Coach software allows using this sensor
for dB-measurements (up to 124 dB).
Range: -45 .. 45 Pa,
Resolution (12-bit): 22 mPa
Can be used to:
? measure sound waveforms and beat
patterns,
? investigate human voice and sounds from
various musical instruments,
? measure the speed of sound through air
and other materials
