Research into the neurological technology behind I-Doser is sparse. Peer-reviewed studies exist suggesting that some specific binaural beat mixes can affect aspects of mental performance and mood, [4] [5] act as analgesic supplements [6] or affect perceptions, [7] but there have been no formal studies of any effects of mixes particular to I-Doser.
Binaural beats work by presenting two different frequencies to each ear that synchronize brainwave activity. Those two methods can be combined to improve sleep quality by targeting both the sensory experience and brainwave alterations.
The neuroscience of music is the scientific study of brain-based mechanisms involved in the cognitive processes underlying music. These behaviours include music listening, performing, composing, reading, writing, and ancillary activities. It also is increasingly concerned with the brain basis for musical aesthetics and musical
Monaural beats are combined into one sound before they actually reach the human ear, as opposed to formulated in part by the brain itself, which occurs with a binaural beat. This means that monaural beats can be used effectively via either headphones or speakers.
The brain utilizes subtle differences in loudness, tone and timing between the two ears to allow us to localize sound sources. [10] Localization can be described in terms of three-dimensional position: the azimuth or horizontal angle, the zenith or vertical angle, and the distance (for static sounds) or velocity (for moving sounds).

There are two main methods used to create a binaural effect: Dummy head recording The dummy head or Head and Torso Simulator (HATS) are based upon the average dimensions of a human head and torso. They consist of acoustic materials fitted with ear and mouth simulators [ 5 ] as well as two microphones inserted within each ear canal, typically at ...
The precedence effect or law of the first wavefront is a binaural psychoacoustical effect concerning sound reflection and the perception of echoes.When two versions of the same sound presented are separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single auditory event; its perceived spatial location is dominated by the location of the ...
In producing binaural media, the sound source is recorded by two separate microphones that remain in separate channels on the final medium, whether video or audio. [47] Listening to a binaural recording through headphones simulates the sound localization by which people listen to live sounds. For the listener, this experience is characterized ...
