The wireless sound sensor measures sound pressure levels in decibels (dB) using a condenser microphone. The sensor is equipped with an OLED colour display that shows sensor information and measured values. This makes the sensor suitable for use as a stand-alone measuring instrument.
This wireless radiation sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programmes/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
The sound sensor supports A-weighting (dBA) for human hearing and offers adjustable measurement ranges for different environments.
The selected range is displayed on the screen.
Technical specifications:
-Measuring ranges:
40 .. 80 dB
60 .. 100 dB
80 .. 120 dB
-Resolution: 0.1 dB
-Warranty: 36 months
-OLED display: 0.96" 128 x 64px
-Maximum sample frequency: 1 Hz
-Battery life: 8 hours when fully charged (rechargeable)
-Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0
-All sensor specifications can be found in the Manual, see Downloads.
Suggestions for physics and NLT practicals:
-Measure sound levels in different environments
-Investigate the effect of distance on sound intensity
-Compare the sound intensity of different sound sources
-Test the effect of sound insulation
-Investigate the effect of frequency on sound intensity
-Investigate the logarithmic nature of the decibel scale
