Hi there.

This site is the result of many experiments. My basic interest dealt with the influence of vibration on sound perception and materials that carry certain vibrations.

During the course of this site, I will disclose many of my findings and introduce a couple of products that impressively document the validity of new concepts for audio interpretation.
