This sensor has two modes of operation. In slow mode it can be used to measure sound-pressure level in decibels. In fast mode it can be used to compare different sources of sound, their waveforms can also be displayed. The frequencies of tuning forks and wind-chimes can be determined and simple electronic signal generators calibrated using it. With two sound sensors the velocity of propagation of sound in various media can be determined by timing a pulse travelling between them.
The sound sensor is located in a plastic box accessible to the atmosphere via a hole in its side.
*Requires connection hardware, sold separately.
Experiment Duration: 25 milliseconds to 31 days.
Operation Modes:
Range | ADC Resolution | Accuracy | Resolution | Max Sample Rate (S/sec):
Level: 40 to 110 dB, 10 bit, +/- 2 dB, 0.1 dB, 100
Signal: 0 - 1024, 10 bit, 1, 1, 10,000
