How sound affects us


Julian Treasure, of The Sound Agency, discusses how sound effects us physiologically, psychologically, cognitively and behaviourally in this short video. The stress-inducing bell/buzzer at 0:44 is neither as loud nor as long as one of the bells in my working week – affecting hormones (cortisol), heart rate and brain waves. His recommendation is five minutes (or more) of birdsong per day.
