Everyday we're surrounded by millions of sounds - ambient ones like the hum of the air conditioner, as well as more attention-grabbing sounds, such as human speech. Neuroscientist and musician Seth Horowitz joined Ian Punnett (Twitter ) to discuss how sound affects us, and in turn, how we've learned to manipulate sound to alter the way we think and feel. People can have difficulty acclimating to the sounds of city or the country, depending on where they're from, he detailed. If a city person goes to the country, the quiet can be disturbing because the lack of sound can seem like a warning that something is wrong, while the reverse is true for the country person going to the city. He also revealed that each city has its own unique band of sound around it, based on various factors.
