Best Answer: Motorcycles are generally louder because of the length of the exhaust system, comparatively to an automobile. The shorter you go, the louder you get.
Earplugs and earmuffs can be used together to achieve even greater sound reduction. Use of earplugs and earmuffs is recommended when noise exposure is particularly high. Do not listen to loud sounds for too long. If you donât have hearing protection, move away from the loud sound. Give your ears a break from the sound.
