Use the music you love to become more efficient, relaxed, healthy, and happy. At this very moment, you are surrounded by sound. Pause for a minute and try to listen to it all: the chatter of a passing conversation, the gentle whoosh of air vents, noise from a nearby street. We rarely pay attention to all that we hear, but every noise in our environment has the ability to affect our mood, our productivity, even our health-for better and for worse. Drawing on a decade's worth of groundbreaking brain science and research, bestselling author Don Campbell and sound expert Alex Doman's Healing at the Speed of Sound® provides practical advice, exercises, and over 100 interactive links that help you create the perfect soundtrack for every task and enjoy a full, rich, and truly harmonious life.
