Sound level and noise pollution are key measurements in environmental science. Our Sound Level Sensor gives you true sound level measurements with both dBA (matches the sensitivity of the ear) and dBC (responds equally to all frequencies) scales. Use in the classroom as a computer-based Sound Level Sensor or with an Xplorer as a portable sound level meter away from the classroom. Three switch-selectable ranges (from 30 dB to 110 dB) allow for greater functionality and flexibility. Measures both sound level and sound intensity.
Typical Applications:
-Explore sound levels outside the classroom
-Discover the logarithmic relationship between sound level and sound intensity
