“Mood disruption leads to your body activating a fight-or-flight response,” says Walker.
( Do you have chronic stress? Look for these signs.) These loud or repetitive sounds don’t just damage the membranes, hair cells, or nerves that allow us to hear-they can also disturb our sleep and trigger a cascade of problems throughout the body. “You can be exposed to so much sound that it destroys your hearing,” says Erica Walker, an epidemiologist at Brown University. When those soundwaves enter your ear, they make tiny membranes, bones, and hair cells inside vibrate, which triggers electrical signals that your brain interprets as sound.īut when that sound is extremely loud or frequent it can actually harm the human body. From a blackbird’s song to the rumble of a passing train, sounds are produced by vibrations moving through the air, ground, or water in invisible waves.
