What are Electronic Ear Defenders and how do they work?


Last Update 4 years ago

Electronic ear defenders are ear defenders incorporating an electronic sound reproduction system. 

At low levels of noise, the sound detected by a microphone on the outside of the ear defenders is relayed to a loudspeaker in the ear defender cup. 

At higher levels of impulse noise, the electronic circuit cuts out, leaving the inherent attenuation of the ear defender to provide the protection.
