  • Title: On the overload effect of sound impulses to the inner ear.
    Author: Wagner H, Berndt H.
    Journal: Arch Otorhinolaryngol; 1981; 232(2):179-85. PubMed ID: 7271587.
    Abstract:
    Test series with both continuous and intermittent sound exposure to guinea pig ears yielded an area within the coordinates load frequency and load level in which a dose principle is valid more or less exactly. Exceeding the upper (level) borderline of this area provokes a damage of the organ of Corti nearly independent of the load dose. Sound levels of such order of magnitude mainly occur at sound impulses. However, to estimate the hair-cell damaging effect of a given sound impulse one needs its time or frequency function in addition to the peak level. A first order approximation seems to be possible by means of a 1/3-octave band level analysis.
