The Sensear Heavy Vehicle Communication Solution (HVCS) enables clear transmission of two-way radio communications and stereo audio for operating heavy vehicles at industrial sites. The combination of noise from different factors can bring a worker’s noise exposures into the 90 dB to 95 dB range, at which most occupational health and safety sanctions require actions to reduce exposure. By using the HVCS, in most cases the exposure is dropped by 10 dB or more. Other features include the ability to charge the headsets in-vehicle if prior charging was missed; built-in redundancy, allowing the original speaker to be re-enabled via internal relay operated by a lockable key switch; and generic cabling harnesses for custom installation. The system meets heavy-vehicle standards including dust, water, and vibration requirements.
