Acoustic Calibrators 

  • Calibration sound pressure level : 114.0 dB and 94.0 dB ± 0.3 dB SPL re: 20μPa (114.0 dB is the principal sound pressure level)

  • Equivalent free-field level : -0.12 dB for 1/2” microphones

  • Frequency : 1 kHz ± 1%

  • Harmonic distortion < 2 %

  • Stability after pressing On ± 0.1 dB after 2 seconds

  • Minimum stabilizing time : 10 seconds after coupling microphone and calibrator

  • Reference conditions : 101.3 kPa, 23 ºC and 50 % RH.

  • Verify audiometers quickly and accurately using ANSI S3.6-2004 Specification for Audiometers.

  • Test virtually every type of transducer such as supra-aural, extended range circumaural, bone vibrator, hearing aid, insert earphone, and speaker.

  • Automatically correct the RETSPLs for microphone, coupler, and all other response adjustments using AUDit™ software.

  • Perform level and frequency adjustments during audiometer tests.

  • Qualify audiometric booth ambient noise with real time 1/3 octave analysis and fast pass/fail results (MPANL).

  • Store and recall tests in databases; query databases by audiometer, technician, date, etc.
