Hi,

I'd like to make a box for testing microphones. Not something accurate enough for absolute measurements but something good for measuring changes over time and detecting damage. Has anyone done this before? Any tips?

I'm thinking of a box about 1 foot square and about 4 feet long lined with 1" of insulation. A full range driver at one end - say a Dayton RS100-8 - and lots of insulation at the other end, and a removeable panel with a mic clip on the inside.

Cheers,

Michael
