Das Cortische Organ nach Knallbelastung durch schwere Waffen (Raster-EM-Studie)

Guinea pigs were exposed in different angles to the noise of a 155 mm canon. The inner ears were studied by means of scanning electromicroscopy right after the exposure. Hair cell damage was never observed in the basal coils. Corresponding to the frequency and to the SPL-maxima the hair cell injuries were mainly found in the 3rd and 4th coils. These findings support the hypothesis of a frequence and SPL-related hair cell damage.
