PASCO Wireless Sound Sensor

Purpose: 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. Sound Wave Sensor: The Sound Wave Sensor measures relative changes in sound pressure level as sound waves are incident on the sensor. Key Features: - Wireless and portable Wirelessly measures sound wave data at high sample rates (100 kHz) - Two sound sensors in one (sound wave and sound level) - High quality sensing element intended specifically for laboratory experiments Connects seamlessly to Scope and FFT displays in both SPARKvue and PASCO Capstone software Threaded 1/4-20 socket for easy mounting and alignment/positioning Educational Topics: Loudness, sound intensity, and the decibel scale Sound wave properties and characteristics Measure the speed of sound with an echo Fourier transforms and sound wave analysis Human ear response and frequency dependence Observe and measure beat frequencies Telephones and dial tones Resonance and standing waves in a closed or open pipe What's Included: 1× USB charging cable 1× Threaded handle for mounting the sensor to a ring stand
