What's this 'rare sensory hearing loss' that singer Alka Yagnik was diagnosed with?

A sudden sensory hearing loss is a medical emergency as it can become irreversible if not aggressively treated in 48-72 hours. The causes may range from simple viruses like Herpes, Varicella, and Mumps or sudden loud exposure to noise levels above 85 dB. According to a doctor, once the treatment is initiated, the chances of recovery are usually 70 per cent and above. The disorder affects only 1 per cent in bilateral ears as compared to single ear.
