Intense sound exposed ears destroy the sensory hair cells and sensitivity of the auditory neurons. This temporary defect on the sensory neurons and particular frequency selectivity are unclear. The current study organizes the stimulated activity of the auditory neurons units to describe the normal and sound exposed neurons, this sensitivity is compared between normal and sound exposed chicken. Sensitivity curves, spikes discharge rate and coefficient variation were measured in both animals. The frequency tuning curves of sound exposed ears show slightly less frequency selectivity than the normal ears over all stimulus frequency. Finally, the results indicated that the high sound intensity harmful for frequency selectivity by auditory neurons and other sensory epithelium in cochlear duct.
