How many types of sound are there?

What are the 5 properties of sound?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself. The wavelength itself is a longitudinal wave that shows the compressions and rarefactions of the sound wave.
Which type of sound is called noise?
Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. … Acoustic noise is any sound in the acoustic domain, either deliberate (e.g., music or speech) or unintended.
What is Sound explain?
