Human mechanoreceptors, such as Pacinian corpuscles, can detect vibrations up to 1,000 Hz, frequencies between 30 Hz and 120 Hz are generally considered to have a calming and relaxing effect, which is why they are often used in therapeutic contexts.40 Hz specifically, has been widely studied in vibroacoustic therapy and other fields due to its ...
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.

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.
Thermal effects are due to the absorption of the sound waves and result in heating of biological tissue. Non-thermal effects are from cavitation, microstreaming and acoustic streaming. [29] [21] Cavitation is the main non-thermal effect of therapeutic ultrasound. [4] [21] Cavitation results from the vibration of tissue causing microscopic ...
Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, [1] speech, [2] music, [3] or tactile stimuli.

The fundamental function of this part of the ear is to gather sound energy and deliver it to the eardrum. Resonances of the external ear selectively boost sound pressure with frequency in the range 2–5 kHz. [2] The pinna as a result of its asymmetrical structure is able to provide further cues about the elevation from which the sound originated.
