Humans cannot normally hear 52Hz.
The typical hearing range of humans is between 20 to 20,000 Hz although humans can in ideal conditions hear sounds as low as 12 Hz.
The ability of humans to hear low frequencies decreases rapidly throughout a persons life.
Most speakers cannot produce sounds at 52 Hz or lower.
52 Hz sound is equivalent to the musical note G#1, which is the 12th lowest key on a conventional 88-key piano keyboard; or, the 4th finger position on the lowest string (E1) of a double bass.
Humans are able to hear when sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum.
The eardrum then vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
These bones are called the malleus, incus, and stapes.
