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.
Experiment Duration: 25 milliseconds to 31 days.
Range and operation modes:
Level: 40 to 110 dB
ADC resolution: 12 bit
Accuracy: ±2 dB and 1 signal
Resolution: 0.1 dB and 1 signal
Max Sample Rate (S/sec):
A connection between your sensors and hardware is required. You can choose from the USB Module, Wifi Module, RF Module, or Display Module. A Battery Module is also required for any connection other then USB Module, which is powered through the cable.
