Vibroacoustic therapy (VAT) is a type of sound therapy that involves passing low frequency sine wave vibrations into the body via a device with embedded speakers. [ 1 ] [ 2 ] This therapy was developed in Norway by Olav Skille in the 1980s. [ 3 ]
In the context of psychology, a coping strategy is any technique or practice designed to reduce or manage the negative effects associated with stress. While stress is known to be a natural biological response, biologists and psychologists have repeatedly demonstrated that stress in excess can lead to negative effects on one's physical and psychological well-being.

In music, acoustic waveguide methods, such as a large pipe organ or, for reproduction, exotic loudspeaker designs such as transmission line, rotary woofer, or traditional subwoofer designs can produce low-frequency sounds, including near-infrasound. Subwoofers designed to produce infrasound are capable of sound reproduction an octave or more ...
Music therapy is distinctive from musopathy, which relies on a more generic and non-cultural approach based on neural, physical, and other responses to the fundamental aspects of sound. [9] Music therapy might also be described as Sound Healing. Extensive studies have been made with this description. [10] [11]
For example, mounting a tactile sound transducer in a chair or couch in a home cinema or video game setup can give more of a sense of "being there". For such use, the transducer is often connected to the LFE channel of an A/V receiver. Tactile sound is often used in combination with a subwoofer so that low frequencies can be both felt and heard ...
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.
Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency low-mid-frequency response of a sound system in the room and are one of the biggest obstacles to accurate sound reproduction.
Examples of resonating type bass traps include a rigid container with one or more portholes or slots (i.e. Helmholtz resonator), or a rigid container with a flexible diaphragm (i.e. membrane absorber). Resonating type bass trap achieves absorption of sound by sympathetic vibration of some free element of the device with the air volume of the room.
