Induced deafness is a term that refers to hearing loss caused by external factors such as exposure to loud noises or certain medications. Some synonyms for induced deafness include noise-induced hearing loss, ototoxicity, drug-induced hearing loss, and acquired hearing loss. Noise-induced hearing loss occurs when a person is subjected to loud sounds over a prolonged period. Ototoxicity, on the other hand, refers to hearing loss caused by certain medications. Drug-induced hearing loss results from chemicals in medications that damage the ear. Acquired hearing loss involves hearing loss acquired over time due to various reasons, including exposure to noise, aging, and illnesses.
