However, active noise compensation with NoiseGard combined with passive hearing protectors results in a reduction of noise of approx. 25 dB in the 25-500Hz frequency range. The total attenuation resulting from active and passive noise compensation is about 30 dB over the entire audio range Connector assignment Technical data HeadphonesMicrophone incl. preamplifier HMECGeneral data HMECHMEC HMECHMEC 305-C HMDCTechnical data HeadphonesHMEC HMEC 305-CHMEC HMDCCertificate of Conformity
