What exactly is sound? Sound is all around us, its the noise that we hear, people’s voices and much more but what is sound actually defined as. Sound is pressure waves, traveling through the air. It makes sense when Professor O’Malley stated without air there is no sound, since the definition of sound is waves traveling through the air. We’ve been learning about pitch and frequency since probably middle school and its determined by the frequency but the thing that confused me in this lecture was the tutorial we watched about understanding sound waves. It made no sense to me even after Professor O’Malley explained it but it seemed as if the entire class was a little on the confused side. I am looking forward to discussing “How music got free” on Wednesday!
