What we have used is small etched piezo devices taped to equipment platforms and feeding a sensitive gain stage (actually a modified phono stage). This gives good results but you have to trial and error a lot to get a reference point from which you can then further study vibration patterns and get meaningful, consistent results. Radio Shack used to sell a small flat piezo mic that can be used. Regards, Richard at www.vantageaudio.com
Measuring Vibration in Equipment
There are alot of threads on shelf material and tweeks that cut down on vibration. Is there a device that measures this vibration? I think I remember of hearing of such a tool before my audiophile days for testing crates for shipment but I cant remember what it was called. In The Complete guide to Home Audio they suggested using a stethescope. Has anyone tried this?
