Understanding Sound: From Waves to Auditory Experience

This chapter explores the fascinating world of hearing and sound perception. Sound is generated by pressure waves created through vibrations, which are transmitted by air. Key concepts such as loudness (measured in decibels), pitch (the frequency of vibrations), and timbre (the quality of sound) provide insight into our auditory experience. It also discusses the structure of the ear, highlighting the outer ear’s role in collecting sound waves and the inner workings of the organ of Corti. Understanding how we perceive and locate sounds enriches our auditory world.

Presentation Transcript

  1. Chapter 6 Section 3: Hearing

  2. What we hear • Stimulus for sound is a wave of pressure created when an object vibrates • The vibration causes molecules in a transmitting substance (usually air) to move together & apart

  3. Auditory Experience • Loudness: intensity of a pressure wave. • Measured in decibels • Pitch: frequency of a pressure wave. • How rapidly the air vibrates

  4. Timbre: The distinguishing quality of sound • complexity of the pressure wave • When many frequencies are present but not in harmony, we hear noise • When many frequencies of the sound spectrum occur, they produce white noise

  5. An Ear on the world

  6. Soft funnel shaped outer ear is designed to collect sound waves • Sound wave passes through an inch long canal to strike the ear drum • Vibration is passed along to the hammer, anvil, & stirrup

  7. Actual organ of hearing is the organ of corti

  8. Constructing the auditory world • Use our perceptual powers to organize patterns of sound & to construct a meaningful auditory world • Need to know where sounds are coming from • Depend on having two ears • Hard to locate sounds coming from above or directly behind your head

  9. Name that sound • Sound 1 • Sound 2 • Sound 3 • Sound 4 • Sound 5 • Sound 6 • Sound 7 • Sound 8 • Sound 9 • Sound 10 • Applause • Crumbling • Cutting Paper with Scissors • Hair Mousse • Pad Lock Opening • Sea Lion • Cards Shuffling • Velcro • Bathtub filling up • Applying soap to hands
