| Abstract |
Doctoral dissertation on the sensitivity of the ear to impulse noise and on the methods necessary for assessing the risk of hearing damage. Contents: physiological and metrological fundamentals; measuring equipment and methods of evaluating results; results of measurements in Swiss industry; acoustic data on weapons and industrial noise sources; hearing damage due to impulse and continuous noise (analysis of 250,000 cases studied by the Swiss National Accident Insurance Fund); injury caused by civilian and military explosive devices and firearms. The data suggest: that the scaling factor for impulse noise given by the relevant DIN/VDI standard overestimates the risk of injury; that impulse noise louder than 125dB(A) can permanently damage the inner ear; that, for impulse noise of short duration, analyses in 1/3-octave and octave bands are most appropriate. |
