Type 4297 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.

 Uses

  • Measurement and verification of pressure-residual intensity index
  • Sound-pressure calibration at 251.2 Hz (Type 1 IEC 60942)

Features

  • No need to dismantle the probe when calibrating
  • Optimised for use with Type 2270-G Sound Intensity system for phase enhancement
  • A complete sound-intensity calibrator in one unit
  • Built-in sound source for sound-pressure calibrations with acoustic-feedback system to automatically adjust for variations in atmospheric pressure
  • Built-in broadband sound source for pressure-residual intensity-index measurements
