DEC is the inventor of Ambient Hearing Protection which is, among others, sold under the Crescendo brand. Ambient Hearing Protection is invented to overcome the problem of muffled sound perception and reduced situational awareness as experienced with other hearing protection solutions using simple resistive tube filters.

Using our patented mesh and membrane technologies combined with a large inlet aperture and high-frequency catcher technology, users retain full situational and spatial awareness. Speech perception is even improved, especially in loud environments.

DEC produces a wide range of acoustic passive filter solutions for various applications suitable for both custom moulded protection and universal fit including.
