ZeroSound develops product to reduce sound for first responders

CALGARY — Building on its OEM agreement to supply a North American manufacturer of fire trucks to protect first responders from dangerous noise, Calgary, Canada-based ZeroSound has reportedly developed a product to reduce hazardous siren noise inside the cab of emergency vehicles by 55% to 75%.

“Having already made key innovations in digital noise suppression over large urban and industrial areas, our team has made another significant breakthrough: a 55% to 75% reduction of siren noise inside the cab of emergency response vehicles. This is a dramatic step forward in protecting first responders from continuous exposure to dangerous noise produced by sirens without impacting the siren’s operations outside the cab,” said Norm Bogner, President & Co-founder.

According to the World Health Organization, noise pollution is a growing global problem not only for first responders but for millions of people who encounter loud sounds in daily life. Elevated noise is known to cause hearing impairment, hypertension, annoyance, sleep disturbance, and heart disease. Traditional noise reduction materials include simple barriers or insulation that absorb and reflect sound waves with varying effectiveness over small areas while ZeroSound’s digital platform measures and physically cancels the sound waves using patented hardware and software over targeted areas and broad urban and industrial zones.

“This development of ZeroSound’s AntiSiren™ is a major breakthrough and opens global opportunities in the fire, ambulance and law enforcement markets while building on the company’s capabilities to reduce urban noise pollution and providing the data to report on its effectiveness.”
