Does higher rpm mean louder?
Does higher rpm mean louder?
Because pitch is just frequency, and rpm is a kind of frequency. Although this is likely not accurate, you can imagine that each engine stroke produces one wave crest of the sound it is making. Increasing the RPM thus increases the rate at which these crests are produced, increasing its pitch or frequency.
