Question 1

Psychophysics

Answer 1

studies the relationship between physical properties of the world and our psychological perception of them

Question 2

Fourier Analysis

Answer 2

• The mathematical process of calculating a complex tone’s simple tone components
• Complex tones can be built up from simple tones
• Human cochlea performs Fourier Analysis when we hear sounds

Question 3

Sinusoidal Pattern

Answer 3

a sound whose instantaneous sound pressure is a sinusoidal function of time. A pure tone has only one frequency component.

Question 4

Simple Tones

Answer 4

• A simple tone is a sound wave whose pressure level follows a sinusoidal pattern over time
• Also known as sine wave tone

Question 5

Sinusoidal Pattern

Answer 5

• Regular amplitude and frequency
• Has a smooth, undulating pattern,
• Lasts at least 10 minutes with a fixed period of three to five cycles per minute and an amplitude of 5-15 bpm.

Question 6

Complex Tones

Question 7

Fourier Analysis in the Cochlea

Answer 7

• Cochlea performs Fourier Analysis on each sound we hear
• Auditory Nerve Fibres are positioned along the length of the cochlea
• ANFs fire action potentials at a constant resting rate

Question 8

Auditory Nerve Fibres

Answer 8

• a bundle of nerve fibers that carries hearing information between the cochlea the brain.
• Send action potential to brain at a constant resting rate

Question 9

Neurons

Answer 9

• Neurons are the building block cells of our central nervous system, especially in our brain.

Question 10

Cytoplasm

Answer 10

• the jelly-like material that fills cells and covers axons

Question 11

Interstitial Fluid

Answer 11

• the water-like liquid in which cells are bathed
