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.

Step-by-step solution

Pitch is the characteristic of sound that determines its shrillness or sharpness, which depends on the frequency of the sound wave. A higher frequency corresponds to a higher pitch and a sharper sound. A sound of a single frequency is called a tone. Pitch and loudness are independent characteristics; pitch depends on frequency, whereas loudness depends on the amplitude of the sound wave. Thus, a high pitch sound need not be louder. In general, the vocal cords of females are shorter and vibrate at a higher frequency
