Sounds exceeding ------------- dB are potentially injurious to the cochlea -
Sounds exceeding 85 dB are potentially injurious to the cochlea, especially with prolonged exposures.
The loss typically begins in the high frequencies (especially 4000 Hz) and, with continuing exposure, progresses to involve the speech frequencies.
What is the Most Frequent cause of Sensory Hearing Loss ?
Presbyacusis is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or associated structures of the inner ear or auditory nerves.
The hearing loss is most marked at higher frequencies.
Antineoplastic agents most commonly associated with ototoxicity -
Antineoplastic agents most commonly associated with ototoxicity are the platinum-based compounds cisplatin and, to a lesser degree, carboplatin.
