Question

What is the difference between the sound produced by regular and irregular vibrations?

Answer 1

When a sound is produced by regular vibrations, it is more uniform and melody in nature. e.g. Music generated by a muscial instrument is produced due to regular vibrations. On the other hand, when a sound is produced by irregular vibrations, it is unpleasant and mostly noisy in nature. e.g. Sound produced due to racing of a motorbike is due to irregular vibrations.
