Wave World What happens to sound waves when you record a song? New

Jon Chase joins singer-songwriter Charlie-Anne Bradfield in the studio as she performs her song 'Butterfly'. As Charlie-Anne sings, Jon traces the path of the sound waves. He builds a large model to see how the sound waves travel through air. Jon's microphone made out of a plastic cup works just like the real one, turning sound into electrical waves. After the studio engineer records the song, Jon plays it back on a loudspeaker he has made out of a couple of paper plates. Teacher notes: When learning about sound, this is a simple but effective illustration of how microphones and loudspeakers work. Students might explore further by building a model microphone or loudspeaker. Teachers might demonstrate this effect using a large loudspeaker and placing grains of rice or small pieces of paper on the front diaphragm to show the vibrations at different amplitudes and frequencies of sound. Teachers could link the science here to careers in sound engineering and music technology.
