If warnings and instructions must be clearly heard, that tests normal ear protection beyond its limits. The ideal solution for this is ear defenders with leveldependent attenuation technology. Harmful noise is damped to a level less than 82 dB and the ear is reliably protected. Nevertheless they ensure that warning signals, speech and process noise can be heard. Also allows clear communication over long distances when used in combination with a radio device or phone. Modern devices now offer the wearer a wide variety of additional supplementary functions: Volume regulation of level-dependent function, balance control, equalizer and volume control for external input signals. Stand- ards Type Protection against EN 352-1 Passive ear defenders It protects the ear by passively shutting out the environment. In its pure form this type of ear protection requires no additional electronic equipment. EN 352-4 Level-dependent ear defenders An electric acoustic function amplifies weak external signals at the ear. As the intensity of the signals and noise reduces, the amplification is reduced. Noise pulses are blocked entirely. EN 352-5 Ear defenders with active noise compensation The noise level is reduced by overlaying the sound waves with corresponding time-shifted (phase-shifted) waves composed of about the same sound pressure level and frequency. This technology shows itself to best effect with low-frequency noises at high decibel levels. EN 352-6 Ear defenders with communication equipment The ear defenders with integral microphone can be used for wireless communication. In addition, they can be connected to a smartphone telephone call. These special functions are for use in combination with passive ear defenders and also with level-dependent ear defenders. EN 352-7 Level-dependent earplugs Like EN 352-4 for earplugs. EN 352-8 Ear defenders with conversation function Ear defenders with integral radio or the facility to connect a smartphone or MP3 player, e.g. for monotonous activities in a noisy environment. In order to exclude any additional hearing hazard the sound pressure level is limited to 82 dB (A). 78 SGD
