8. Pain/discomfort in ear
◉ Sound. Answer: Vibratory energy transmitted by pressure waves
through a medium
◉ Resonance. Answer: The natural tendency for an object to vibrate
with great amplitude at one frequency than at others when a driving
force is applied
◉ Frequency. Answer: Number of complete compression-rarefaction
cycles per second
◉ Pure Tone. Answer: Produced by simple repeated alternations of
compression and rarefactions
,◉ Wavelength. Answer: The distance between one wave crest or
trough to the next

pure tones present simultaneously
