Question
The loudness of sound I is ____ to the loudness of sound II.
- >
- <
- =
- None of the above
Hint:
Amplitude determines the loudness of the sound
The correct answer is: >
- The loudness of a sound depends on the amplitude of vibration producing the sound.
- The bigger the amplitude is, the louder and more intense the sound.
- Therefore, loudness of sound I is greater than loudness of sound II.
- So, the correct option is a.
