I wonder if a large well marked (graduated) compass would work? It would be crude but maybe useful?
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?
