Otoacoustic emissions and other ear check equipment for use by hearing care professionals

Hearing loss is a condition wherein a person cannot hear sounds at or above 20 decibels (dB). It can manifest in various degrees, ranging from mild to profound, and can affect one or both ears. Hearing loss can result from a variety of factors, such as early-onset childhood hearing issues, ear infections, age-related hearing deterioration, noise-induced damage, and the use of ototoxic medications. The consequences of hearing loss can be far-reaching, affecting a person's ability to communicate and potentially leading to delayed language development in children.
