Hey guys, I've got to give a 10 minute oral at school (with a mate) about technical sound production etc. I was just wondering if you guys had any ideas and tips/help for me? We were thinking of bringing in a couple foldbacks/mixer to demonstrate how to hook everything up, whilst explaining the difference between inputs/jacks/leads etc. Then we were going to go on about sound waves/frequancies and how they're produced by different sized cones/tweeters.. And also how sound travels/bounces of certain surfaces. That was about the extent we thought to today. We are going to use powerpoint to show frequancy charts and diagrams of how the sound bounces and best ways to place amps/mics etc. So, what else do you think we should do? How should we structure it? Any general tips? We will be doing this talk (it's an assesed thing for English class, pretty important) to a small audience including two examiners/judges... How could we involve this audience? Should we try get someone up to plug some stuff in and work it all? Or would that be wasting too much time? Cheers guys.
