Audio therapy is the clinical use of recorded sound, music, or spoken words, or a combination thereof, recorded on a physical medium such as a compact disc (CD), or a digital file, including those formatted as MP3, which patients or participants play on a suitable device, and to which they listen with intent to experience a subsequent beneficial physiological, psychological, or social effect.
Non-thermal effects are from cavitation, microstreaming and acoustic streaming. [15] [21] Cavitation is the main non-thermal effect of therapeutic ultrasound. [4] [21] Cavitation results from the vibration of tissue causing microscopic bubbles to form. These microscopic bubbles may directly stimulate cell membranes and cause shockwaves within ...
Beginning in 2008, Dr. William Tyler and his research team from Arizona State University began an investigation and development of this alternative neuromodulation without the harmful effects and risks of invasive surgery. They discovered that this low-power ultrasound is able to stimulate high neuron activity which allows for the manipulation ...
The cell autonomous instruction hypothesis states that differentiation into Type I and Type II neurons occur following the last phase of mitotic division but preceding innervations. [9] Both types of neuron participate in the encoding of sound for transmission to the brain.
Audio-visual entrainment (AVE), a subset of brainwave entrainment, uses flashes of lights and pulses of tones to guide the brain into various states of brainwave activity. AVE devices are often termed light and sound machines or mind machines. Altering brainwave activity is believed to aid in the treatment of psychological and physiological ...
One of the first groups known to heal with sound were the aboriginal people of Australia. The modern name of their healing tool is the didgeridoo, but it was originally called the yidaki. The yidaki produced sounds that are similar to the sound healing techniques used in modern day. The sound of the didgeridoo produces a low, bass frequency.
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).

Graph showing a typical Auditory Brainstem Response. The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA) or brainstem auditory evoked potentials (BAEPs) or brainstem auditory evoked responses (BAERs) [1] [2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.
