Industrial Filters Factsheet
Designed for industrial use, the work protection filter effectively reducesย high frequency noise to allow for a longer, safe exposure time.
Unlike other hearing protection such as foam earplugs, it does not โover-dampenโ lowerย frequency noise, allowing the user to converse & maintain communicationย ability whilst in-use.
Incorporated in Snugs custom-fit hearing protection,ย 100% compliance through all day use is guaranteed.
Noise exposure: Work Environments & Tools
The workplace and at-home DIY tools can produce loud, damaging noise. If you are exposing your ears to over 80dB for a prolonged period of time, then it is imperative to wear hearing protection to prevent damage. If you are unsure of the noise level in your environment, use a Sound Level Meter to measure your dB exposure.

Safe noise exposure times
In the workplace, it is a legal requirement to provide hearing protection for employees who are exposed to noise above 85dB. The louder the environment, the shorter the safe exposure time.
By using custom fit hearing protection with a Snugs Work 25 Red Filter, you increase the safe exposure time, making it an essential piece of PPE in the workplace as well as at home.

How it works
Industrial noises have a tendency to be louder at higher frequencies. Snugsย work filters have been designed to provide relatively flat dampeningย (attenuation) to remove low frequency noise and therefore aid speechย communication, with progressive reduction above 4 kHz to removeย damaging high frequency sounds.
Our industrial filters ensure the user has a constant air flow into their ear,ย minimising the occlusion effect and reducing chance of irritation in the earย canal. Used in Snugs custom fit hearing protection, comfort is guaranteed.

Attenuation levels:
The attenuation data shown in the table above is calculated according to CEย norm EN-352-2 by ISO 4869.2 for high (H), medium (M), low (L) frequencyย level and as the single number rating (SNR). NRR is calculated according toย standard ANSI S3.19-1974.
When used in Snugs custom fit hearing protection,ย the level of attenuation can vary depending on theย individual. A custom fit provides the perfect canalย seal, meaning when the filters are incorporated intoย a Snug, the user can achieve higher levels ofย attenuation than in the data above.

Why use filters?
Tinnitus
1 in 7ย people in the UK are living with Tinnitus.ย 35% of people reported developing Tinnitus after exposure to louse noise. Chris Martin, Coldplay: โIโve hadย tinnitus for about 10 years, andย since I started protecting my earsย it hasnโt got any worse - touchย wood. Looking after your ears isย unfortunately something you donโtย think about until thereโs a problem. Iย wish Iโd thought about it earlier.โ
Hearing loss
Around 1.1 billion young peopleย are at risk of noise induced hearingย loss due to unsafe listeningย practices. The rise of personal listeningย devices including headphones areย a contributing factor, as well asย inadequate hearing protection inย nightclubs and at live events.
Sustainability
More thanย 1 billion foam earplugsย end up landfill each year. Switching toย custom fit, re-usable silicone earplugs reduces waste. Made from a hypoallergenicย silicone which is easy to clean.
