Acoustic filters
A full range of acoustic filters for custom and universal ear plugs for music, leisure, industry and security.
The need for the use of hearing protectors is obvious nowadays. Appropriate hearing protection is chosen on different selection criteria such as required sound attenuation, wearer comfort, workplace environment and a possible need for communication. Discomfort and over attenuation are two of the main factors that result in incorrect fitting and use of hearing protection, especially when using disposable foam ear plugs or earmuffs. Dynamic Ear acoustic filters are available in a range of attenuation levels with either linear or non-linear attenuation.
All DEC filters are 100% acoustically tested.
Dynamic Ear non-linear acoustic filters provide a large open air passage into the ear minimising the occlusion effect whilst also keeping the ear ventilated for the ultimate user comfort. Dynamic Ear linear acoustic filters use membranes according to our patented membrane technology. The membranes are designed to have the biggest surface in the given form factor. Since the membrane is made of a breathable material, this leads to optimal breathing of the filter, which enables moisture in the ear canal to escape keeping the ear canal cool and providing all day comfort. The advanced membrane is tuned to maintain natural hearing, speech being clearly heard.
Choosing the correct level of attenuation is vital. Over attenuation removes the user from his environment, further increasing the level of occlusion and making the user feel detached. Over attenuation and non-linear attenuation is a risk, especially in a work environment. Dynamic Ear acoustic filters are available in a range of fixed attenuation levels suitable for all exposure levels, ensuring that the correct level of noise is reduced.
The DI range of acoustic filters are non linear whilst the DM acoustic filters provide linear attenuation. Both types are suitable for both custom moulds and universal earplugs. All DEC products have the same diameter coupler allowing the user to swap from one product to another, eliminating the requirement and investment in multiple custom moulds. For example, the user can use the same earplugs for both In-Ear headphones and acoustic filters to create a hearing protection solution.
