Sounds which can't be heard: The hidden secrets of an MP3 player

Tuesday 21 February 2012, 7.00PM

Speaker: Professor David Howard, Department of Electronics

The Science of Sound lecture series

This lecture will review the way our ears process sound in terms of what is relevant to hearing music. It will then consider the operation of the MP3 player in terms of how it is that a CD recording can be very significantly shrunk in size without obvious audio degradation; when you purchase an MP3 track you only receive around 10% of the original CD quality audio data!

The Science of Sound lectures glimpse into the fascinating world of sound: the discoveries of Pythagoras and the basis of music, how the sounds around us affect our mood, how our hearing system can be tricked and finally we explore what we want from recordings of music and whether we get it.

Other lectures in this series:

• Music and Physics
• Listening to the world: Sounds and the environment
• Perfect sound forever? Recording and recreating sound
