I wondered if you had any thoughts... I want to record the difference between a room with and without extensive acoustic treatment. I am setting up a small business selling nicely made stuff that would not look out of place in a persons living room, but is also very high quality. What I thought might be a nice idea is to record the difference on a CD that people can hear. I was thinking I might use a Neumann dummy head to try and capture this in a bin-aura recording that people could listen to on in-ear headphones. As most people have a pair that came with their walkman or something it shouldn't be too hard for them to do. Any tips or other ideas though? I think I can get hold of one of these mic's but I have never used one before. Do you think it would even work?
