Motorcycle
broom!
An alliteration for a motorcycle bike sound could be "bellowing beast." This phrase captures the powerful and distinctive roar of a motorcycle engine while emphasizing the intensity of the sound. The repetition of the 'b' sound creates a rhythmic effect that enhances the imagery.
motocicletta.
rumbling, go to youtube and search for motorcycle exhaust to get a better idea
As the motorcycle moves towards the observer, the frequency of the sound heard will increase due to the Doppler effect, making the sound seem higher pitched. Conversely, when the motorcycle moves away from the observer, the frequency will decrease, causing the sound to seem lower pitched.
Your ears will find out that the closer you are to the motorcycle the louder the noise will be. We measure the sound pressure by a SPL meter.
Leak in the exhaust system?
as the motorcycle approaches the observer, the frequency increases.
eather a blown head or a bad rod
NO it wouldn't sound right.
Write an experiment to find the velocity of sound?
