What is loudness of sound? What factors does it depend on?
A loud sound has high energy. Loudness depends on the amplitude of vibrations. In fact, loudness is proportional to the square of the amplitude of vibrations.
(a) What is meant by the 'loudness' of sound ? On what factor does the loudness of a sound depend ?
(b) Draw labelled diagrams to represent (a) soft sound, and (b) loud sound, of the same frequency.
(a) How can you show that a sounding tabla is vibrating?
(b) On what factor does the loudness of a sound depend?
How does the loudness of sound depend on its amplitude?
(a) Explain the term 'pitch' of a sound. On what factor does the 'pitch' of a sound depend ?
(b) Draw labelled diagrams to represent sound of (a) low pitch, and (b) high pitch, of the same loudness.
