On of the rather powerful technologies that I have found for entraining particular brainwave states is the light-sound machine. These use not only the binaural sound beats in stereo headphone, but also flashing goggles that stimulate the visual fields. Due to the flashing lights it is important that individuals with seizures should probably not use these devices, or if they do, they must choose the color of the light goggles carefully: refer to the manufacturer’s guidelines. Please discuss the use with this technology with your own neurologist if you fit in this category. These devices range from the quite simple to the technologically sophisticated. Some, such as the newer David Paradise units also include cranial electro stimulation if preferred. Some of both the Sonic Pro and the David devices allow for audio input from your favorite music to be included in the sound portion of the experience. The newest versions of the devices actually allow the sounds from music to alter the light frequency for stunning visual effects.
These devices have multiple built in programs for specific brainwave pattern entrainment, and allow for the download of additional programs from the manufacturer. Some even have a computer interface program that allows for you, the user, to create your own programs. Note: for those of us Apple users, none of the companies have direct Mac compatible software or even downloads, although some of them allow Windows emulation software to allow for this function.
The research sited from the David Paradise site indicates that much like other binaural technologies, although the device helps you reach a particular brain state, it doesn’t mean that you are forever dependent on the device to reach the state in the future. The ability to reach the state reliably apparently allows more rapid access to the state during meditation without the device at later dates.
A somewhat dated book, by Michael Hutchinson, which reviews the technology in some depth is MegaBrain. This is well worth a read, as there is no single source that gives background material in more detail.
Like Binaural Beats Institut said, the Light and Sound machines require a lot of experience in Brainwave Technology. I think in near future these technologies will further develop and will be more known by people. Thanks for sharing. 7 chakras Meditation
The Light and Soundmachines require a lot of experience in Brainwave Technology. The Book you referred to is one of the most comprehensive sources. But how often the user study those information before using the soundmachines?
