Hearing relies on tiny hair cells in the ear that can detect air pressure changes smaller than a billionth of atmospheric pressure. These hair cells not only convert vibrations into electrical signals for the brain but also actively amplify and fine-tune sounds, letting people distinguish subtle differences in pitch and tolerate an immense range of volumes. Remarkably, in silence, most ears actually emit their own unique tones. Understanding and potentially restoring these cells could transform treatments for hearing loss.
