1145 - Wireless Sound Level Sensor

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

• Animal Activity Studies
• Field Studies
• Road Safety
• Ear Design
• Noise Pollution
• Sound Insulation
• Sound Decay
• Sound Frequency
• Tuning forks with 3 different frequencies 192 (green line), 256 (red line) and 512 (blue line) recorded with a 50 µs interval for 20 ms with the Y axis set to the Min to Max scale.
• Investigating waves, superposition and Fourier transforms 
• Interference in sound waves 
• Amplitude and Frequency
• Speed of Sound by measuring a reflected pulse
• Please note: It is not possible to conduct Speed of Sound experiments that measure sound travelling from one Sound sensor to another Sound sensor. If two Bluetooth or USB connections are made the maximum number of samples per second reduces to 50 (interval of 20 ms) which is not fast enough to capture this event.
• Air Resonance
• Resonance in a pipe
• Sound Waves: monitoring the effect of altering frequency and amplitude, waveforms of musical instruments, beat patterns 
• Voice recognition – the sounding of a single letter using a fast recording time
