| Zusammenfassung | Intended as an input to international standardisation, reference hearing thresholds for the calibration of audiometric equipment have been determined using "clicks" as test signals and several kinds of earphones, a loudspeaker and also a bone vibrator as transducers. The threshold measurements were carried out with groups of 25 test persons with normal hearing capability following as far as possible the ISO-preferred test conditions. The influence of different parameters on the results, like click duration, polarisation mode, repetition rate, gender and age of the test persons or type of ear simulator, was studied. The results mainly depend on the type of ear simulator used to calibrate corresponding audiometers. Together with the results of another investigation carried out in Denmark, the data of the present study shall form the basis for the coming International Standard ISO 389-6 on reference hearing thresholds for acoustic test signals of short duration. |
