Otoplastics Ear muffs

Properties and uses -

Cotton wool or wads: plasticized and provide maximum protection of approximately 10 dB(A)

- Plugs: specially designed plastic rods or deformable foam rolls that are worn in the

ear, the maximum protection is approximately 10 to 15 dB(A)

- Universal earplugs: specially shaped, they are attached to a bracket that is worn around the neck, depending on the pitch they provide protection between 10 and 15 dB(A) - Otoplastics: made from a cast in the ear, contains an interchangeable or adjustable

filter that blocks noise, maximum protection approximately 25 dB(A)

- Ear muffs: look like large headphones, close the ears from the environment, protection factor depends on the type of hood and the level of the sound,
