The American Bose at the initiative of this technology
Nevertheless, it took several years of experimentation for this technique to be operational. It is the American giant of electronics Bose who seized it by inventing this noise reducer. And this gadget should arrive soon on the market. "Several German manufacturers would already like to incorporate this technology in their cars," said Anicet Mbida.
Contrary to popular belief, these helmets would not necessarily increase vehicle prices. "On the contrary, it could even lower the cost of manufacturing cars because there will be less need for soundproofing and caulking to filter the outside noise," said Anicet Mbida.
