Ear Defenders Worn in the Workplace

Ear defenders or earmuffs are essential if you want to keep your hearing at the top of its game, especially when you’re working in loud, harsh environments. Choosing the right Personal Protection Equipment (PPE) can make an instrumental difference to your quality of life, and with so many different options available, there’s something for every situation.

Whether you need discreet noise protection to shield your eardrums from factory noise, or thermal ear defenders to safeguard against cold conditions and extreme sounds, MAD4TOOLS has the right product for you.

Understanding Protection Levels

Ear defenders are rated according to how much protection they offer against different decibel levels and different levels of noise attenuation.

We know that sometimes it can become a little overwhelming when trying to understand the level of protection you need. So, below we’ve helpfully outlined what these terms mean.

What is attenuation?

Attenuation is the process of losing noise energy and is recorded by SNR values assigned to each set of ear defenders. The higher the SNR, the higher the level of noise attenuation provided by the hearing protection.

What does SNR stand for?

SNR is a Single Number Rating system. The SNR value is used to understand the level of noise attenuation provided by different ear protectors.

What is HML?

When you’re shopping for ear protection, you’ll also notice H, M and L ratings, which refer to the level of noise attenuation.

H = High frequencies

M = Medium frequencies

L = Low frequencies

Understanding decibels (dBs)

We use decibels (dB) to measure sound intensity, which means a log scale is used rather than a linear system. For example, for every three-dB increase, the intensity of a sound will roughly double to the human ear.

To work out your daily and weekly noise exposure and estimate the performance of hearing protection you need, you can use HSE’s handy calculators.
