Sound is all around us. But how is it generated? How do we hear it? This course introduces the student to acoustics and ear training-two essential areas of knowledge for every engineer. Through extensive demonstrations and listening sessions, the student comes to understand how the ear and brain work together to interpret sounds, and how the skilled engineer can use that knowledge to produce sound that has a desired effect. Room acoustics play an important part in our appreciation of recorded sound. The student learns about room environments and how to achieve the best possible room design. We discuss the physics of how musical instruments generate and direct their sounds with a direct connection to how to record those instruments.
