Heart Prototype - Aging Exhibit



This unit let visitors hear four different rates of heartbeats (buttons on the left) and four different types of beats (buttons on the right). There was also a touch membrane for people to feel the beats with their fingertips.


Listen here...

Abnormal Heartbeats

Murmur

Triple Cadence

4th Sound


These sounds were created by Dr. Yurchak at Massachusetts General Hospital.


Here's another view of the prototype . The digital repeater is clearly visible. We used a Mackenzie MacFi unit that can playback eight different messages. Also notice the EQ unit. Everything above 200hz is cut out and the low end is boosted. This was done to give the touchpad the needed volume to move the membrane.
