Guinea-pig experiments were made for objective assessment of the effects of high-intensity noise on the acoustic analyzer. Noise with intensity above 100 dB for 11 hours is accompanied with thresholds rise by 20 dB. In some animals hearing loss was observed for several weeks after discontinuation of a sound impact. In the,, presence of initially high conductive hypoacusis intensive sound load may cause short-term sound threshold lowering with further damage to neurosensory cochlear elements.
