Our company

DYNAMIC ear filter is a superior quality, patented product manufactured in Europe by Dynamic Ear Company (DEC). We have been developing and producing a wide range of innovative in-ear acoustic solutions for hearing protection, communication and earphone applications for more than 15 years at our ISO 9001-certified facilities in Delft, the Netherlands.

Leading hearing care group

The DYNAMIC ear filter brand and DEC are part of Sonova Group, the world’s largest hearing care solutions provider with 4,000 private hearing care centres that supply 65,000 independent hearing specialists worldwide. Sonova manufactures personal audio devices, wireless communication systems, hearing aids, cochlear implants and hearing protection products.

Worldwide distribution

Our products are available through a worldwide network of OEM and private label distribution partners who serve multiple markets and industries, including the PPE, military, motorsports, professional music, leisure and aviation sectors. Each year, we produce millions of innovative acoustics filters that are accommodated in custom ear moulds by specialised laboratories.

Our technology

DEC was founded in 2007 to develop Dynamic Sound Technology (DST) – patented electronic acoustic attenuation technology with a valve that can be used as stand-alone hearing protection. The technology can also be embedded in communication systems, headphones or even hearing aids and hearables. In 2009, DEC started producing patented linear acoustic filters, and in 2011, we were the first to market linear attenuating universal fit hearing protection, also known as ‘ambient hearing protection’.

Impulse filters

In 2014, DEC developed and patented impulse (shooting) filter technology with the first batch shipped to the British Ministry of Defence. Today, this technology is used not only by police and security services and NATO soldiers but also by recreational shooting and hunting enthusiasts.

Earpiece leakage testing

Our first Acoustic Leakage Tester (ALT) was patented and launched in 2015. This software runs on an iOS device. Combined with a sensor unit, the ALT measures whether an earpiece is properly sealed in the ear, ensuring that the right protection level is being provided.

Filtered foam

Filtered Foam Earplugs are the latest invention in the ambient hearing protection range. These earplugs incorporate a filter with large sound port and mesh attenuator. The technology allows for natural sound, good speech intelligibility and excellent sound direction. The viscoelastic memory foam provides a comfortable and easy fit. Filtered Foam Earplugs are the ideal ambient hearing protection for everyday situations and for use in the workplace.

Our quality

Dynamic Ear Filter complies with PPE regulation EU 2016/425 and is, if applicable, tested according to EN 352-2020, ANSI S3.19-1974 and ANSI IPIL standards. All our products are manufactured in-house at our ISO 9001:2015-certified production facilities in the Netherlands.

100% quality check

We perform a 100% final acoustical test on all our filters to ensure optimal hearing protection and sound quality before they leave the factory. When correctly fitted, the protection level stated on the packaging is guaranteed.

Sustainable packaging

Our filter sets come in fully biodegradable packaging made from 100% compostable and recyclable PaperFoam®.
