C) number of activated hair cells.
D) cheering of the people in the stands.
Loudness
The subjective perception of the intensity of sound, often associated with the amplitude of sound waves.
Activated Hair Cells
Sensory cells located in the inner ear that are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
Number of People
A quantitative measure representing the total amount of individuals within a defined context or group.
- Understand the mechanism of sound wave propagation from the outside environment to the auditory cortex.
- Understand the importance of decibel levels in assessing the volume of sounds and their effects on auditory health.

Final Answer :
C
Explanation :
The brain interprets the loudness in the stadium based on the number of activated hair cells in the ear. When a sound reaches the ear, it causes vibrations that stimulate hair cells within the cochlea, which then send signals to the brain to interpret as sound. The louder the sound, the more hair cells are activated, and the brain perceives it as a louder sound. The number of people in the stands, number of players on the field, and cheering of the people may contribute to the overall volume of the stadium, but the brain's interpretation is based on the number of activated hair cells in the ear.
