How many decibels do cars make?
These are given in Schedule 1 of the Regulation. Levels are established from a set testing procedure also described in the Regulation. For most cars, the relevant exhaust noise limit is 90 decibels and for motorcycles, 94 decibels.
Do lower speed limits reduce noise?
Reducing speed limits is the quickest, cheapest and most equitable way of cutting traffic noise. Slower is quieter. Lower speeds also allow the noise benefits of electric cars to be spread more widely and are foundational for traffic reduction.
How loud is it in decibels in your car if it is traveling 55 miles per hour?
Driving at 55 mph with the top down produced sound level measures above 85 decibels in 80% of convertibles tested. Driving at 75 miles per hour produced average sound levels of about 89.9 decibels, about equivalent to the sounds made by vacuum cleaners, big trucks, a garbage disposal, or loud music.
Does road noise increase with speed?
Road traffic noise: the impact of speed There is a measureable link between traffic noise and speed. In urban areas with speeds of between 20 and 35 mph, reducing speeds by 6 mph would cut noise levels by up to 40%. Reducing 70mph and 60mph speeds on urban motorways would cut noise by up to 50%.
How far does car noise travel?
Levels of highway traffic noise typically range from 70 to 80 dB(A) at a distance of 15 meters (50 feet) from the highway. These levels affect a majority of people, interrupting concentration, increasing heart rates, or limiting the ability to carry on a conversation.
What is an acceptable level of traffic noise?
