Wireless communication helmet
Wireless communication system integrates transmitter, receiver, and smart skull transceiver. There is no external cable. All communication modules are embedded in the helmet. The tin foil shielding isolation technology is used to protect the human body from the harm caused by radiation.This equipment can be used with air breathing apparatus and heavy chemical protective clothing!
The bone conduction sound-controlled helmet-type wireless communication system adopts the new digital processing (DSP) technology and incorporates the algorithm for recognizing the pronunciation of human vocal cords, so that the external sound and impact are not recognized, and at the same time, it provides the dual function of eliminating noise. , to eliminate noise, it is digitally processed and checked before transmission, so that the sound quality is clear, and the noise can be eliminated up to 110dB in a noisy sound environment that affects the communication quality.
