“Noise is the silent killer in the sense that it’s really a cumulative effect,” says Mathias Basner, an associate professor at the University of Pennsylvania School of Medicine. “If you expose yourself to high levels of noise, that won’t kill you. Our bodies are pretty amazing; we can tolerate a lot of things, especially with a one-time exposure. If it’s not extreme, we’ll deal with it. But if you’re exposed to high noise levels on a regular basis for prolonged periods of time, that’s when we pay the price — and humans are really bad at making that connection.
Basner knows what he’s talking about: He’s been investigating the effects of sound, particularly related to sleep disruption, for decades, and the FAA is currently funding his research around the impact of aircraft noise exposure on sleep. Basner and his team completed the first part of that study right here in Philly, with a group of people living near Philadelphia International Airport, and recently published the results in the International Journal of Environmental Research and Public Health.”
