Preliminary experience with the impulse noise simulator to identify individuals particularly sensitive to sound

The impulse noise simulator test, in which an impulse noise in the frequency range of 1000-2000 Hz with a peak pressure below the limit of tolerance is produced, constitutes, according to our experience so far, a useful test to recognize the so-called vulnerable ear and to exempt the persons concerned from exposure to impulse noise during their military service or to monitor them audiometrically in connection with firing exercises. The investigations show that TTS after simulator test is higher than after regular shooting exercises with weapons with lower frequency spectrum. This is a remark that bands, produced by weapons with larger caliber are less dangerous for hearing than those with a higher spectrum like G-3 and the simulator.
