The causes may range from simple viruses like Herpes, Varicella, and Mumps or sudden loud exposure to noise levels above 85 decibel (dB).
Veteran Bollywood singer Alka Yagnik, who revealed that she has been diagnosed with a "rare sensory hearing loss" due to a viral attack, has suffered a type of hearing loss caused by damage to the inner ear or the nerve pathways that transmit sound from the ear to the brain.
According to Dr Manish Munjal, Vice Chairman, ENT, Sir Ganga Ram Hospital, Delhi, sudden sensory hearing loss is a medical emergency as it can become irreversible if not aggressively treated in 48-72 hours.
"The centre of the problem is the inner ear organ called Cochlea, where it happens due to damage to the hair cells," Munjal told IANS on Tuesday.
