Detailed explanation-1: -The pitch of sound is determined by the frequency of vibration of the sound waves that produce them. A high frequency (e.g., 880 Hz) is seen as a high pitch, while a low frequency (e.g., 55 Hz) is regarded as a low pitch. Low-frequency sounds include a bass drum, thunder, and a man’s deep voice.
Detailed explanation-2: -Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used.
Detailed explanation-3: -This vibration is that of a pure tone with a frequency equal to 3000 Hz, meaning over the highest frequency of the human voice (soprano: 2 100 Hz).
Detailed explanation-4: -A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
