Sound Mode


The Noumic Device uses one of four different sounds to give information, every three seconds, about changes in your body's tension and relaxation.

Down Tone - indicates that there was some reduction in your body's tension; in other words, you became more relaxed.

Up Tone - indicates that there was some increase in your body's tension; in other words, you became less relaxed.

Level Tone - indicates that there was no change in your body's tension or relaxation. This happens when you are very relaxed.

Beep Sounds - indicates a certain level of relaxation achieved; levels 1 to 10 and beyond.

With just four sounds, you soon understand instinctively what they indicate. So, with this biofeedback device, even your mind can relax while using it!

Sound Samples

Musical notes, representing the down tone sound a Noumic Device makes for more relaxation. Down Tone - indicates that there was some reduction in your body's tension; in other words, you became more relaxed.
Musical notes, representing the sound a Noumic Device makes for increased tension. Up Tone - indicates that there was some increase in your body's tension; in other words, you became less relaxed.
Musical notes, representing the sound a Noumic Device makes for no change in relaxation or tension. Level Tone - indicates that there was no change in your body's tension or relaxation. This happens when you are very relaxed.
Musical note, representing the beep sound a Noumic Device makes to indicate a level acheived in relaxation. Beep Sounds - indicates a certain level of relaxation achieved; levels 1 to 10 and beyond.

About the Sounds

Of course, in sound mode, you can have your eyes closed while using the device. The sound is not too intrusive for relaxation practice. You can listen to music or recorded relaxation instructions and still hear the Noumic Device. If you have good hearing, the sound is loud enough to use the Noumic Device while walking.

Some say it sounds like a little bird next to you helping you to relax!
However, some people find the sounds too intrusive, or even annoying, they prefer Noumic in Light Mode!

Two ways of using Noumic Devices

Noumic Devices measure and indicate changes in skin conductivity. While holding it, if you move your fingers or change holding pressure this strongly affects the level of skin conductivity measured by it. This fact makes the device usable in two ways, see below.

1 - Hold with unchanging gentle pressure.
For monitoring EDA, or GSR.

The device then works as an extremely precise skin conductivity monitor. In 'biofeedback terminology', the device monitors your Electro-dermal Activity, EDA; also known as Galvanic Skin Response, GSR.

Learning to control your EDA / GSR is a method for learning to deeply relax, also helpful for meditation. This is explained more in our 'GSR biofeedback' page.

Suggestions of what to aim for
Get the Down-tone as often as you can.
Get the Level-tone as much as possible.
Try to get the 'levels achieved' extra beep sounds.

2 - Gently change hand-grip pressure.
For monitoring hand muscle tension.

The device then works as an extremely sensitive hand muscle tension monitor. With the instantaneous tension biofeedback information provided you can train yourself in precise control of hand muscles.

Learning control of your muscle tension is a method for improving performance of your whole nervous system; this is explained more in our 'muscle tension' page.

Suggestion of what to aim for
The Down-tone consistently for as long as possible.
The Up-tone consistently for as long as possible.
The Level-tone as much as you can.
By increasing pressure fast but decreasing very slowly, aim to get the 'levels achieved' extra beep sounds.

Important: NEVER squeeze the device tightly.electronic biofeedback device held in the palm of a hand, Noumic design biofeedback machine.
