Noise pollution is more than annoying. Researchers found that consistent loud noises hurt the brain’s ability to function, especially when decoding speech.
Noise is defined as any unwanted sound – it can be a jack hammer incessantly drilling away on the roads outside your apartment on a busy city street: the sound of loud, irritating cell phone ringing, the low hum of a train, or monorail that is located near your domicile. It could even be the decibel-shattering music coming from that car next to you on your morning commute.
Increased urbanization has led to more sound pollution, and while scientists already figured out that this unwanted noise can lead to sleep deprivation, concentration issues, headaches, and irritability, UTD scientists now say it can even impair how our brain processes human speech in a quiet environment.
Consistent loud sounds damage the tiny hairs in our ears that act as receptors. Once they are damaged, they can’t grow back.
