System overview

SoundCheck is an easily configurable system enabling efficient and comprehensive testing of microphones. Utilizing a variety of readily available hardware and software, including anechoic test boxes, measurement microphones, databases, and word processors, SoundCheck can measure and report relevant parameters related to microphone test and me a sur ement. In addition, SoundCheck can control external devices, such as urntables using RS-232, USB, or IEEE interfaces.

SoundCheck’s advanced analysis capabilities can augment the functionality of existing test programs. SoundCheck can run within another program while it collects data and results using ActiveX or command prompts.

One-button Calibration

The entire measurement chain, including reference microphone, audio amplifies, and sound source, is easily calibrated by simply clicking on one button in SoundCheck. An external acoustic calibrator is used to calibrate the reference microphone, which then can be used to calibrate the sound source. The magnitude and phase of the source is equalized for a flat response. The position of the test microphone, relative to the sound source, can be measured acoustically thereby enabling easy alignment to the reference position.

Application-specific Test and Measurement Modules – SoundWare™

SoundCheck is comprised of several SoundWare modules enabling you to create functionality specific to your measurement needs. SoundWare modules include the Signal Generator, Voltmeter, Oscilloscope, Spectrum (FFT), and Real Time Analyzer. For real-time “hands-on” investigation of microphones, the Signal Generator can play a sine wave, a noise signal or any Windows WAV file at a calibrated output level. The response of the microphone can then be analyzed in the time and frequency domain using the Oscilloscope, FFT or Real Time Analyzer SoundWare modules.

Simulated Free-Field Response

Measure the free-field amplitude, phase, and impulse response of any test microphone using the substitution method.
