Cube

Square

square root

- Option 1: Cube Root

- Loudness increasing with the cube root of amplitude means it would rise very slowly.

- Not commonly seen in physical phenomena for sound loudness.

- Option 2: Cube

- If loudness were proportional to the cube of amplitude, it would increase very rapidly.

- Uncommon in the context of sound perception.

- Option 3: Square

- Correct Answer: Loudness is proportional to the square of the amplitude.

- This is because sound intensity, which relates to loudness, is proportional to amplitude squared.

- Option 4: Square Root

- Loudness increasing with the square root implies a slower growth.

- Not aligned with how sound loudness works.
