This dual range sensor accurately measures both sounds pressure level in decibels (dBA) or waveform (mV). To make the measurements meaningful to learners, the sensor has been designed to approximate the normal human ear in the range and intensity that it 'hears ' sounds.
Ranges:
- 40 to 110dBA
- Waveform ±2000mV
Applications Include:
- Sound frequency
- Speed of sound
- Sound insulation
- Sound decay
- Air resonance
- Ear design
- Animal activity studies
- Noise pollution indoors and outdoors
- Sound waves: Monitoring the effect of altering frequency and amplitude, wave forms of musical instruments, etc.
