What should be the sound level of the exhaust fumes?

The sound level of exhaust fumes should not cause hearing problems, which emphasizes the importance of maintaining a reasonable noise level for safety and comfort. Excessively loud exhaust systems can lead to hearing damage over time, both for the driver and for people nearby. Regulation of sound levels ensures that vehicles operate within acceptable limits that promote public health and safety.

Maintaining a sound level that does not contribute to hearing problems aligns with broader regulations and standards meant to limit noise pollution in urban environments. This approach helps ensure a harmonious coexistence of vehicles in public spaces and reduces the risk of noise-related health issues for both drivers and pedestrians.
