Types of hearing loss

Hearing loss isn't one thing. Knowing which kind you have explains why some sounds are clear and others aren't.

Sensorineural

The most common type. Tiny hair cells in the inner ear wear down with age, noise exposure, or other causes. It usually starts with high-pitched sounds, which is why speech can seem loud enough but not clear, especially with background noise. It's permanent, and hearing aids are the usual treatment.

Conductive

Something blocks sound before it reaches the inner ear: earwax, fluid, an infection, or a problem with the eardrum or middle-ear bones. It's often medically treatable, so we refer you to a physician first when we see signs of it.

Mixed

A combination of both. We'll address the medical part first, then talk about hearing aids for the rest.

How hearing is measured

Your hearing test produces a chart called an audiogram. It shows the softest sound you can hear at each pitch, measured in decibels (dB). Hearing at 20 dB or better is considered normal. The further below that line your results fall, the more help you're likely to need. We'll walk you through your own chart, line by line.

When to see a doctor right away

Sudden hearing loss, especially in one ear, is a medical emergency. If it happens, contact a physician or urgent care the same day. Fast treatment can make a difference.
