Hood fhf11890112 phone

The phone cover perfectly improves audibility in a noisy environment, where, for economic reasons, it is necessary to install open phones. Acoustic insulation can be up to 25 dB (A). The special shape of the hood and its inner lining made of sound absorbing material optimally limits noise. It is also difficult to eavesdrop on phone calls outside the mask. The best acoustic effect is obtained when the back of the protective mask is directed towards the noise source. The protective hubcap is made of steel or stainless steel sheet and contains an inner lining with sound absorbing mineral wool panels, protected by a perforated curtain plate. The ambient temperature can be from -60 to +60 ° C.
