My DDs are revising at the moment (GCSEs and A levels) and we seem to have an ongoing disagreement about whether or not you can actually take in any information if you are listening to very loud music. I suggested that background music would be ok if it helps with concentration and this is what DD2 is doing but DD1 appears to be listening to thrash metal that is turned up to full volume. I don't want to turn it into a battle of wills as any comment from me and she will flounce off and start slamming doors and that will be the end of any work today - but can you actually learn anything with loud music on?
