• B) 0.40
• C) >0.40
• D) 0.40 N
• E) 2.5 N

Definitions:

Timbre

A quality of sound that distinguishes different types of sound production, such as voices or musical instruments.

Auditory Receptors

Sensory cells located in the inner ear that convert sound waves into electrical signals that can be interpreted by the brain.

Cochlea

A spiral-shaped, fluid-filled inner ear structure that is essential for hearing by converting sound waves into nerve impulses.

Slight Time Difference

A minimal discrepancy in timing between events or processes, often critical in sensory processing and perception.
