Reference hearing threshold levels for short duration signals
Hearing thresholds for clicks and tonebursts were measured on 26 otologically normal persons (age 18-25 years) using the earphones Sennheiser HDA 200 and Telephonics TDH 39. The test signals are specified in IEC 60645-3 and in ISO 389-9. The acoustic test signals were presented both as a single stimulus and as repeated stimuli with the repetition rate of 20 Hz.
The frequencies used for the toneburst were: 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. Test signals and measurement methods were all in accordance with the recommendations given in ISO 389-9: Preferred test conditions for the determination of reference hearing threshold levels. The results are given as peak-to-peak equivalent threshold sound pressure levels (peETSPL).
The results are in good agreement with other sparse results from literature and are part of the basis for the ISO 389-6 standard from 2007.
