Which of the following sounds has the lowest pitch?
A man’s deep voice (100 Hz)
Pitch is the quality of a sound that tells us whether it is "high" or "low", and it is decided by the frequency of the sound wave (the number of vibrations per second, measured in hertz, Hz). The lower the frequency, the lower the pitch; the higher the frequency, the higher (shriller) the pitch.
Comparing the four frequencies given, the smallest value is 100 Hz, which belongs to the man’s deep voice. A lower number of vibrations per second produces the lowest-pitched sound.
The tuning fork at 512 Hz and the child’s voice at 350 Hz both vibrate faster than 100 Hz, so they have higher pitch. The bird’s chirp at 1500 Hz has the highest frequency of all, making it the most shrill (highest pitch), not the lowest.
Hence, the sound with the lowest pitch is the man’s deep voice (100 Hz).
