Subject: vibro acoustic cushions
Content-Transfer-Encoding: 7bit
Content-Type: text/plain; charset=us-ascii
I am researching a technique that hospitals use to relax patients and that is
GENERATING musical vibrations under a cushion.

Some manufacturers use speakers and others use devices that vibrate but make no
noise. I was wondering if anyone could help me with this.

I am looking for the devices that make no noise but create vibrations. I am
told that the vibrations go through a liquid crystal type medium which the
cushion is filled with.

Any help would be appreciated.

Thank You
David
