What Decibel Level of Car Noise is Considered Disturbing?
1 Answers
Car noise above 60 decibels is considered disturbing. Noise is the sound produced by irregular vibrations of an object, which can cause irritability and pose health risks when the volume is too high. Methods to Improve Car Noise: Engine noise, road noise, and tire noise are all structural noises primarily caused by vibrations. The most effective solution is vibration damping. Adding damping plates combined with sound-absorbing pads can effectively reduce road noise and tire noise. Road noise and tire noise result from friction between the tires and the road surface, generating vibrations and noise. Therefore, vibration damping is the best approach. Comprehensive application of damping plates or specialized damping plates, sound-absorbing pads, and door seals on the fenders, floor, and doors can address tire and road noise at three sources: vibration damping, sound absorption, and sound insulation. Wind noise occurs when wind pressure exceeds the sealing resistance of the doors. Thus, enhancing sealing resistance is the most direct and fundamental solution. Door seals and inner seals can effectively resolve this issue.
