Measuring Sound

Level The Sound Level Sensor has a sufficiently fast response to allow for the measurement of speed of sound in air or solids (using 2 sensors) and to capture waveforms. It is equally responsive to all sound frequencies within its range and can measure both transient and continuous noise.

frequency response

Electret microphone has a broad frequency response of 100 Hz to 7 kHz. The microphone capsule is positioned in the end cap of the Sensor. The Sound Sensor is not waterproof.
