The presence of subjective tinnitus is an important aspect in the evaluation of hearing loss induced by noise. Tinnitus due to this condition is characterised by a frequency of 3,000 Hz or above and is closely related to the frequency range of maximal hearing loss. Tinnitus below 1,000 Hz is not induced by noise, and indicates the presence of a different cause for the hearing loss. This type of...

متن کاملReview of salicylate-induced hearing loss, neurotoxicity, tinnitus and neuropathophysiology
Salicylate's ototoxic properties have been well established, inducing tinnitus and a sensory hearing loss when administered in high doses. Peripherally, acute dosing of salicylate causes frequency dependent reductions in DPOAEs and CAP amplitudes in low (<10 kHz) and high (>20 kHz) frequencies more than mid frequencies (10-20 kHz), which interestingly corresponds to the pitch of behaviourally-m...
