How can you reduce noise?

Driving in higher gears, such as 4th or 5th, at moderate speeds helps reduce engine noise because the engine runs at lower revolutions per minute (RPM). Lower RPM means less engine noise, which is important in built-up areas to minimize disturbance to residents. In contrast, driving at high engine revolutions or high speeds increases noise, so these do not help reduce noise. This rule helps promote quieter, more environmentally friendly driving in urban settings.
