Sound Level Sensor
Sound Level Sensor

This dual range Sound Level Sensor accurately measures either sound pressure level in decibels (dBA) or waveform (mV).

The sensor has been designed to approximate the normal human ear in the range and intensity that it 'hears' sounds.

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.

Practical Teaching

The SmartQ Sound Level Sensor can be used to investigate a number of scientific experiments such as:

  • Speed of sound
  • Sound insulation
  • Air resonance
  • Decay of sound with distance
  • Ear design
  • Animal Activity Studies
  • Field Studies
  • Noise pollution indoors and outdoors
  • Effect of sampling rate on sound quality
  • Sound Waves: monitoring the effect of altering frequency and amplitude, waveforms of musical instruments, beat patterns, etc.
  • Voice recognition, the sound of a single letter
