Question

Which one of the following statements regarding pitch of sound is 'WRONG' ?
(A) Pitch refers to sharpness of sound.
(B) Tone refers to the single frequency of that wave.
(C) High pitch sound need not be louder.
(D) In general male sound is sharper than that of a female.

• A. D
• B. A
• C. C
• D. B

Hint:

Pitch is the sharpness of a sound and is set by frequency, not loudness; a female voice is sharper than a male voice.

Answer 1

The Correct Option is A

Step 1: Facts:
Pitch follows frequency; loudness follows amplitude. Female voices have higher fundamental frequencies, typically about 200 to 250 Hz, against about 100 to 150 Hz for male voices.

Step 2: Evaluate:
Statements about pitch meaning sharpness, tone meaning single frequency and pitch being independent of loudness are all accurate.

Step 3: Answer:
The statement claiming male voices are sharper is wrong. That statement is (D), so the answer is option A.

Final Answer:
Option A (statement D). \[ \boxed{\text{(A) statement (D)}} \]
