| Abstract |
Based on audiometric tests (in the range 10-20kHz) of 106 operators of ultrasonic equipment, as well as on measurements of high-frequency noise, the problem of safety limits for high-frequency noise exposure was investigated. Analysing the relation between noise levels of 1/3 octave bands at center frequencies of 10, 12.5 and 16kHz and the accumulated noise dose on the one hand, and changes in hearing at 10-12, 11-13 and 14-16kHz respectively, on the other hand, a harmless level up to 80dB and a harmless noise dose up to 1 unit for people not older than 40 years have been found. For older people this level and this noise dose can be harmful. |
