What is attenuation in hearing protection?
Flat attenuation is an equal reduction in sound across frequency. In hearing protectors, flat attenuation is achieved by re-introducing a resonant peak in the earplug response to simulate that of the average normal open ear.
What kind of hearing protection do I need?
85 Decibels (dB) – the “Action Level” where hearing protection is required. 90 dB – the OSHA, 8 hour average exposure limit. 100 dB – exposures longer than 15 minutes are not recommended. 110 dB – regular exposure of more than 1 minute risks permanent hearing loss.

What is SNR and NRR?
Put simply, SNR and NRR are two standards for measuring the attenuation of a hearing protection product. SNR is the EU standard, while NRR is the US standard. It’s important to consider the noise environment that the protection will be used in, and how well the hearing protection product is fitted.
How do I choose the best hearing protection?
The best hearing protection will lower total noise exposure to below 85 dB. Disposable ear plugs are typically made of soft, pliable foam. They are rolled by hand into a thin tube then placed in the ear canal, where they expand to form a seal. Reusable plugs are made of flexible silicone or rubber and come pre-molded to fit the ear.
What are the different types of hearing protection devices?
There are two main types of hearing protection devices: ear plugs and ear muffs.
Why is hearing protector fit testing important?
In addition to selecting HPDs and documenting the PAR achieved by each worker, hearing protector fit testing is a critical component to worker training. From disposable to reusable, basic ear muffs and communication-enabled headphones with a built-in AM/FM radio, there is an enormous variety of Hearing Protection Devices (HPDs) on the market.
What is the purpose of ear protection?
Some forms of ear protection, like noise-canceling headphones, are usually just used for entertainment purposes. This is usually used by audiophiles who like to listen to music without hearing anything else in the background. Most hearing protection gears just take away a good chunk of the noise.
