Welcome to the Science Room.

In this room you will find articles, links and information on some of the substantial scientific research in sound healing and sound therapy - food for the curious mind!

Building the Cymatics Sounder

Anyone who has attended one of our workshops, or our evening event "Healing the Healer" has seen us use the Cymatics Sounder. It is a graphic example of how sound is capable of moving matter.

water wavesBefore we go any further, let me explain what a Cymatics Sounder (CS) is. In its simplest form, a CS is a resonant chamber. Sound waves enter the chamber, and bounce off of the hard surfaces of the walls of the pipe. In doing so, they behave just like water waves, where two waves cross each other. Waves are additive. A wave peak crossing a wave peak travelling in the opposite direction creates a peak that is twice as high - the sum of the two peaks. A wave peak that crosses a wave trough cancels itself out, and has no height - it's as though the water was calm. This is referred to as a node.

low frequency sound imageWhen you place a membrane over the top of the CS, and sprinkle in a little sand, it becomes possible to see these peaks and nodes graphically. The peaks are high energy areas full of vibration- they shake up the sand, and so they push the sand away. The nodes are very low energy areas, and so the sand gathers there. Just like the image to the left. high frequency sound imageAs you increase the pitch of the sound, the patterns become more complex like the image to the right.

Are the Sounds You Hear Harmful or Beneficial?

Last week I talked about how sound travels and about how sound travels through your body. Some of these sounds are beneficial and some are not. Do you know how to tell the difference?

Here is an experiment that offers you a physical experience of two contrasting sounds:

  1. Take a deep breath. Release the breath slowly with a big sigh.
  2. Check in with your body. How are you feeling right now? Don’t judge it. Just notice.
  3. Click on the track below to listen to its sounds. The track is 22 seconds long. Don’t feel bad if you need to turn it off after a few seconds. It's a little hard to listen to …
  4. Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version here. You also need to have JavaScript enabled in your browser.

  5. Check in with your body again. Do you notice a difference from how you felt before listening to the track?
