Does the sound of meat sizzling on a grill make you salivate? Does the familiar jingle of an ice cream truck evoke a hot summer day? Has the roar of a stadium crowd ever made your heart beat faster? Joel Beckerman, a composer who founded a sonic branding company, writes that "sound is present every moment of our lives, affecting our moods, our reactions, our thoughts, and our choices." But we're mostly unaware of it. We talk with Beckerman about recognizing the sounds that affect us, and how to take charge of your soundscape. Beckerman is co-author of "The Sonic Boom: How Sound Transforms the Way We Think, Feel, and Buy."
