When you clap, a sound is produced. Can you produce sound without utilising your energy? Which form of energy did you use to produce sound? In this chapter we are going to learn how sound is produced and how it is transmitted through a medium and received by our ear. 12.1 Production of Sound. Activity _____________ 12.1.
introduction. Sound is a longitudinal, mechanical wave. Sound can travel through any medium, but it cannot travel through a vacuum. There is no sound in outer space. Sound is a variation in pressure. A region of increased pressure on a sound wave is called a compression (or condensation).

However, the audibile range of frequency of a Person decreases as one gets older since the hearing sensitivity of ears falls for both low and high equencies. The sound of frequency above 20,000 Hz is called ultrasonic, while the sound of requency below 20 Hz is called infrasonic.
