Real-ear attentuation at threshold (REAT) measurements test how narrowband noises of varying frequency are attenuated with and without the custom mold in place. Testing for low-frequency attenuation can help to verify the earmold fit while testing high-frequency attenuation can verify the properties of the filter used. [6] [21]
Earmuffs, external: This ear protection fits snug around the person's external ear. Earplugs, internal: These are ear protection that fit inside of the person's ear canal.

Two people wearing behind-the-neck earmuffs. Thermal earmuffs are worn for protection from the cold. Because the ears extend from the sides of the head to gather sound waves, they have a high skin surface-area-to-volume ratio, and very little muscle tissue, causing them to be one of the first body parts to become uncomfortably cold as temperatures drop.
When used properly, hearing protection can limit the exposure of noise in individuals. Musicians have the ability to choose from several different types of hearing protection, from conventional ear plugs to custom or high fidelity hearing protection. Despite this, use of hearing protection among musicians is low for several different reasons.

Hearing conservation programs [1] are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. . Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at ...
Earwax can be removed with an ear pick or curette, which physically dislodges the earwax and scoops it out of the ear canal. [40] In the West, use of ear picks is usually only done by health professionals. Curetting earwax using an ear pick was common in ancient Europe and is still practised in East Asia.
