How do we hear sound?
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum 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.
How does sound travel from ear to brain?
The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

Is 1100 dB possible?
It’s not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels. The answer is unfeasibly loud, and no, it can’t create a black hole that big. At 1100 db it creates a 5 kg black hole with the same volume as a neutron.

Research says that music tuned from this frequency is easier to listen to, brighter, clearer, and contains more inherent dynamic range.
Is 432 Hz better than 440?
Context: The current reference frequency for tuning musical instruments is 440 Hz. Some theorists and musicians claim that the 432 Hz tuning has better effects on the human body, but there are no scientific studies that support this hypothesis.
