9. When two (or more) sounds are present having a frequency difference of less than
about 20 or 30 Hz, you will hear "beats." The frequency of the beats will be at the
difference frequency. If the frequency difference is larger than about 20 or 30 Hz, a
tone is usually perceived rather than distinct beats. For complex sounds, beats can
arise from any of the partials of the sounds.

14. • A tightly stretched membrane produces sound
vibrations.
•Instruments are struck(with hand, hammer, mallet
etc.) shaken, brushed, rubbed or scraped.
•The size and tightness of the drum head determines
pitch.
•A resonating air chamber amplifies the sound
