What is Hearing Loss ?
Hearing loss is the inability to hear partially or totally in one or both ears. Generally, sound is indicated by ‘frequency’ and ‘intensity’. In ‘frequency’, our ears can normally hear between 20 to 20,000 Hertz. When hearing threshold or the least hearing ability of a person is over 25 dB (decibel), then it can be termed as hearing loss or impairment. Hearing loss treatment involves diagnosis of the type and degree of hearing loss and based on the type and degree of hearing loss the treatment would be either medical or rehabilitative.
