What are the two types of ear protection?
There are three main types of hearing protection that people can wear to help reduce the impact of noisy environment and risk of developing noise-induced hearing loss. These include earplugs, earmuffs and semi-insert earplugs.
What are the four types of ear protector?
Here are four types of ear protectors to help you keep only safe levels of sound coming in.
- Disposable Earplugs / Expandable Foam Ear Plugs. This type of ear protector expands into the outer ear canal to press gently against the wall of the ears. …
- Earmuffs. …
- Ear Caps / Canal Caps. …
- Custom Reusable Earplugs.
How many kinds of hearing protection are there?
There are four basic types of hearing protection: earplugs, muffs, inserts, and plugs.
What is the best type of ear protection?
Earplugs. Earplugs are one of the most effective forms of ear protection, particularly if they are custom made. With earplugs, the canal is completely blocked which protects the hearing from dangerously loud noises. They are typically made of foam or moulded material and may have a protective covering.

What does SNR mean for hearing protection?
What is SNR? SNR is a Single Number Rating system. The SNR value can be used to compare the level of noise attenuation offered by different hearing protectors. To determine acoustic pressure on your ears, you subtract the SNR value from the average noise level measured.
What is safety ear protection?
Hearing protectors are required to prevent noise induced hearing loss. Hearing protection devices reduce the noise energy reaching and causing damage to the inner ear. Ear muffs and earplugs are the most common types of PPE.
What is the difference between SNR and NRR?
While the NRR is the standard for hearing protection attenuation across North America, the Single Number Rating (SNR) is the EU’s standard. Like the NRR, the SNR gives you an estimate of the level of noise reduction that a hearing protection device can provide.
What is the NRR rating?
Noise Reduction Rating (NRR) is a unit of measurement used to determine the effectiveness of hearing protection devices to decrease sound exposure within a given working environment. … The higher the NRR number associated with a hearing protector, the greater the potential for noise reduction.
How do I choose hearing protection?
