Hearing loss can occurs when inner ear or nerve is damaged, which may be caused due to diseases, aging, loud noise, and medications. Hearing amplifier is a small part of hearing aid which makes the sound louder. Hearing amplifiers increase the power of signals and then send them to the ear through speakers.
Hearing aid is useful in improving the hearing and speech of patients. An otolaryngologist investigates the cause of the hearing loss. An audiologist is a hearing health professional who identifies and measures hearing loss and will perform a hearing test to assess the type and degree of hearing loss.
Increase in number of hearing impairment cases coupled with rising costs of hearing aids are expected to drive the growth of the global Hearing Amplifiers Market during the forecast period. Majority of the consumers use hearing amplifiers or personal sound amplification products (PSAPs) as they are considered cheaper alternatives of hearing aids. Hearing amplifiers or PSAPs, are designed to amplify sounds in any recreational environment and are exempt from the Food and Drug Administration (FDA).

Hearing amplifiers are sold directly to consumers as electronic devices without the requirement of a physician prescription. According to National Institute on Deafness and other Communication Disorders (NIDCD), approximately 324,200 cochlear implants have been implanted worldwide. About 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Major driving factors for the growth of the global hearing amplifiers such as an increase in the number of prevalence of hearing impairment patients in old and young population, increasing investment in research and development in ENT field among others.
