Document Summary

Media required- usually air for humans, but also any other material. Movement of molecules (waves of compression and contractions) Frequency and pitch: wavelength- distance to complete one cycle, frequency= rate of vibration of sound source measured in hertz (hz) Short wave length= high frequency: pitch= what you perceive. Intensity and loudness: intensity- amplitude of the sound wave. Frequently referred to as volume: loudness- how we perceive it. Speech signals: spectrograms: display speech by amplitude across time, waveforms: display speech by frequency across time. Vocal fords sit in the tubes and are very much like the string of a musical instrument. Anatomy and physiology of the auditory system: the outer ear. 4 gross divisions of the auditory system: Pathways of sound (forms of transmission of sound) Bone conduction (bc: sound is conducted through the school and stimulates both inner ears simultaneously i. ii.
