Drivers are consistently exposed to higher decibel levels than passengers due to their direct proximity to the engine, constant contact with the steering column and pedals that transmit road vibrations, and greater exposure to wind and traffic noise through the driver’s side window. Unlike passengers, drivers cannot shift position or distance themselves from these sound sources, resulting in longer and more concentrated exposure. Over time, this heightened noise level not only contributes to fatigue and reduced concentration but may also increase the risk of long-term hearing damage if not properly managed.
