Waves crash.Tree branches vibrate.Mosquitoes hum.These phenomena take place every day but not everyone necessarily hears them.Indeed, some sounds happen in places that are hard for humans to access or below the level of what we can perceive.But more and more, scientists are listening in.From a root system up to 90 feet underground, to balloons floating 70,000 feet above earth, a series of recent audible insights are being showcased this week by experts gathering at the annual Acoustical Society of America conference.
