4 important questions on The auditory system - The Nature of Sound
Sound is changes in air pressure that create waves. State the 2 components of sound waves
Amplitude, size or height of these waves
What does the frequency and amplitude of a sound determine? How does high/low frequency and amplitude manifest on graph and in the ears?
Amplitude determines volume, high dB = tall waves mean louder sound and low dB = short waves meaning softer sound
How does the ear respond to sound waves, what is the pathway and the structures involved?
