![]() Students can use this sensor to explore superposition of waves and beat frequencies, while also exploring standing wave harmonics, and the presence of overtones. ![]() With graphs of the sound wave measurement versus time, students can explore and analyze wave properties like wave shape, wave speed, amplitude, frequency, wavelength, and much more. Sound Wave Sensor: The Sound Wave Sensor measures relative changes in sound pressure level as sound waves are incident on the sensor. The PS-3227 Wireless Sound Sensor is two sensors in one wireless package: a sound wave sensor capable of measuring relative changes in sound pressure level as a function of time, and a sound level sensor with both dBA and dBC-weighted scales.
