Somebody has decided to drill a hole to the center of the earth. This is happening about 30 meters away from my place. This noise is louder than it seems and echoes down all my street so loud, I can hear it louder than my music. They start banging before the sun rises and don't stop till around 6pm. They take about 5 minute breaks between each session of banging, that last about 1 or 2 minutes. I've noticed I've started clenching my teeth at home.
Yesterday I learned that low frequencies of sound have the ability to bend around objects. So this banging noise must be really flexible. That's why, when you're at a club and you go to the bathroom, you can't hear the high frequences as well as the low ones.
