All Shield(Music) ‘DM’ filters provide flat attenuation, which means that the filter will equally reduce the amplitude of all frequencies in the range. This maintains a consistent level of attenuation across those frequencies, ensuring sound is not distorted or muffled in any way. 

The number after the ‘DM’ denotes the amount of decibel (dB) attenuation/reduction the filter offers. If you are a musician on-stage and the noise is very loud, then we recommend opting for a DM25. If however you are using your Shield(Music) earplugs to quieten noise in the pub or in quiter setting, then we recommend a DM15 filter.

All filters are removeable from the Snugs so you are able to change them to different attenuation protection depending on the noise environment you are in. You can order spare filters here.

Attenuation in the context of hearing protection is the amount of decibel (dB) noise reduction a filter offers.

Noise Reduction Rating (NRR) is a unit of measurement used to determine the effectiveness of hearing protection devices to decrease (attenuate) sound exposure within a given working environment. Classified by their potential to reduce noise in decibels (dB), a term used to categorise the power or density of sound.

Hearing protectors must be tested and approved in the USA by the American National Standards (ANSI) and CE certified in Europe. Snugs GO Shield is rated at 26 dB NRR and is accredited to test to ANSI S3. 19-1974, ANSI S12.6-2016, ANSI S12.42-2010, EN352 parts 1-8 and AS/NZ S1270:2002 by the National Institute of Standards and Technology (NIST) National Voluntary Laboratory Accreditation Program (NVLAP).

The higher the NRR number in the USA (or SNR in Europe) associated with a hearing protector the greater the potential for noise reduction.

We are able to include a filter in your SnugsMoto (Music) to allow some outside noise in whilst wearing your earphones. Some people prefer this to provide some spatial awareness. The attenuated filter ensures your ears are still protected against damaging wind and engine noise.

Please note, it is not always possible to fit a filter in the Snugs along with the earphone driver. If this is the case, we will inform you and refund you for this part of the order.

Noise is measured in decibels (dB) and the louder the environment, the greater level of protection you will need.

So, if you work/perform in a very noisy environment, we recommended choosing the filter with the highest dB reduction rate. If you're struggling to decide which one you need, please contact us and we will be happy to assist you.

Yes, you can change the filter. We stock a range of filters with different levels of decibel protection, you can order filters here.

Don't forget to add a handy filter removal tool to help you remove the filters from your Snugs

The awareness filter in SnugsAqua offers a 5 decibel (dB) reduction in sound. This means you can still hear and maintain spatial awareness with your Snugs in, making them suitable for surfers who need to hear the waves, as well as other water sport users. Swimmers can now hear their friends and swimming instructors. All the time maintaining a waterproof seal to ensure cold, chlorinated or unhygienic water does not get in.

The filter is waterproof whilst also ensuring a constant air flowing through the ear; this ventilation minimises the occlusion effect and avoids irritation within the ear canal.

Keep your ears dry, clean and ventilated while hearing everything around you.

Supplied with DEC’s DR 5dB attenuated filters. The best attenuated filters in the world CE certified to EN352.
