1. What decides the pitch of a sound?
2. Name the unit used to measure loudness
3. What decides the loudness of a sound wave?
4. If three different sound waves are in simple mathematical ratios, what kind of
sound will they produce?
5. Will sound waves having frequencies of 144 Hz and 240 Hz produce a musical
sound?
6. Which human organ produces sound (voice)?
Answers
Answer:
your answer is
1)Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.
2)DECIBEL UNIT
DECIBEL UNIT IS USED TO MEASURE THE LOUDNESS OF SOUND (Db).
3) The intensity of sound waves determines the loudness of sounds, but what determines intensity? Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. ... Greater amplitude waves have more energy and greater intensity, so they sound louder.
4)Musical or pleasant sound.
5) No, because they are not in mathematical ratio.
6)Larynx is the human organ produces sound (voice).
