Globally, about 500 million people live with disabling hearing loss, the majority of which is sensorineural in nature.

In children, SNHL affects approximately 1–2 per 1,000 live births, making it one of the most common congenital conditions. In adults, prevalence increases sharply with age, with over 50% of individuals older than 75 years experiencing clinically significant hearing loss. Noise exposure, ototoxic medications, and aging-related degeneration further contribute to the growing global burden.

Understanding Sensorineural Hearing Loss and Inner-Ear Disorders

Sensorineural hearing loss (SNHL) and inner-ear disorders affect the sensory cells and neural pathways essential for hearing and balance. These conditions include age-related hearing loss (ARHL), noise-induced hearing loss (NIHL), drug-induced hearing loss (DIHL), as well as genetic forms of hearing loss that can appear at birth or develop over time. Associated disorders such as tinnitus, Ménière’s disease, and balance dysfunction further highlight the complex and widespread impact of inner-ear damage on daily life.
