Sound Intensity Calibrator
Sound Intensity Calibrator Type 4297 is used for on-site sound-pressure calibration and pressure-residual intensity-index verification.
The device is a complete sound-intensity calibrator in one compact, portable unit with built-in sound sources. The acoustic feedback system automatically adjusts for variations in atmospheric pressure and fulfils the IEC 61043 standard.
Sound Intensity Calibrator Type 4297 enables instruments that measure sound intensity to be accurately calibrated. It is intended for use with Brüel & Kjær Sound Intensity Probes Types 3599 and 3654 with Sound Intensity Microphone Pair Type 4197. The microphones must be used with ¼" preamplifiers.
The Sound Intensity Calibrator can be used for calibration of sound‐pressure sensitivity. To do this, the microphones are both positioned in the calibration chamber. There is no need to dismantle the probe, and both microphones are exposed to exactly the same sound pressure (amplitude and phase). A barometer is not needed because an accurate feedback system holds the sound‐pressure level at a constant value.
The broadband sound source is provided for measurement of the pressure‐residual intensity index spectrum. This is used to assess the accuracy of sound‐intensity measurements.
