Sound & Light Machines

Mind Machines

Sound and Light machines for personal use (also known as mind machines) have been on the market for some years now. Advances in technology mean that the models you can buy today are usually more sophisticated and often have more features and options than the originals. They have many uses, including relaxation and encouraging deeper sleep. The best known systems on the market are probably Procyon, Proteus and Sirius however there are many more.

What Are Sound And Light Machines?

There are many different light and sound machines on the market. They vary tremendously in price and features but all consist of essentially three elements:

How Does a Sound Light Machine Work?

Important: If you suffer from epilepsy or or otherwise affected by flashing lights or rhythmic sound do NOT use a sound & light machine without consulting your doctor.

To use a sound light machine, simply get comfortable in a darkened room and put on the eyeshade and headphones. Select a program, close your eyes and relax.

With your eyes shut you will be aware of vague flashes of colour. If using an advanced machine you might be surprised by the number of different visual experiences that can be produced by a few LEDs!

Accompanying the light will be sound. Assuming you are not using music synchronisation then this will be a series of rhythmic pulses, possibly binaural.

Just let yourself drift off. A good light sound sequence is designed to ensure a Frequency Following Response whereby your brain locks on to the frequency of the lights and gradually attunes to it. This is essentially a "leading" mechanism - as the frequency reduces, you relax automatically.

Why Use a Sound and Light Machine?

Sound Light Machines are essentially used to create an "altered state of consciousness". That doesn't necessarily mean anything weird, it could simply mean extreme relaxation.

Some people use sound and light machines to enhace lucid dreaming, meditation and even learning.

Do They Work?

As with all these things it's personal. The best mind machine for you might not work for someone else.

I've bought several light sound machines over the years. Currently I'm using a Proteus Mind Machine and it's great. Although it has a multitude of programs I've found that there are only half a dozen I use on a regular basis.

For me the Proteus unit produces some of the deepest relaxation I've ever experienced. I either use it during the day to "recharge" or at bedtime for a really good night's sleep.
