The cochlea, a spiral-shaped structure in the inner ear, contains sensory cells that convert sound waves into electrical signals.

Unilateral hearing loss refers to the loss of hearing in one ear, while the other ear remains unaffected.

Earwax buildup is a common cause of conductive hearing loss, as it can block the sound waves from reaching the eardrum.

Age-related hearing loss, also known as presbycusis, is the most common type of sensorineural hearing loss, occurring gradually with age.

Otoacoustic emissions are used to assess the function of the inner ear by measuring the sounds produced by the cochlea in response to sound stimuli.

Stapedectomy is a surgical procedure that involves replacing the stapes bone in the middle ear to improve hearing in cases of conductive hearing loss.

Completely-in-the-canal (CIC) hearing aids are worn entirely within the ear canal, making them less visible than other styles.

Tinnitus is the perception of sound in the ears or head when no external sound is present.

Ménière's disease is a balance disorder that causes episodes of dizziness, hearing loss, and tinnitus.

The recommended noise level for preventing noise-induced hearing loss is 85 decibels (dB) for an 8-hour exposure.

Behind-the-ear (BTE) hearing aids are worn behind the ear and connected to a small earpiece in the ear canal.

Sudden sensorineural hearing loss refers to the sudden loss of hearing in one or both ears, often occurring within a few hours or days.

Benign paroxysmal positional vertigo (BPPV) is a balance disorder that causes brief episodes of dizziness and a sensation of spinning, triggered by certain head movements.

Cochlear implant surgery involves implanting a device that directly stimulates the auditory nerve, bypassing damaged hair cells in the cochlea.

Concha hearing aids are worn in the concha of the outer ear, making them less visible than other styles.
