The soundfeelbox, a sensory-tactile stimulation

The soundfeelbox converts sound into structure-borne-sound. It is designed as furniture and can be used as a chair. The top wooden surface converts the sound-waves, emitted by a loudspeaker built under it, into vibrations which are perceived by the body. These vibrations are transmitted from the pelvis to the spine and reach the head. The seating position causes an active and awake situation. The user sits upright and is simultaneously able to work on a table.

The vibration can be modulated from gentle up to strong by the volume control of the amplifier. In this way you can find the appropriate adjustment for each child.

Experiencing the sondfeelbox will enhance the attention and the alertness. The body sensation signalises to the brain “here happens something”. The children will get more focus on their attention and consider their environment more from inside out.

Children, who can't be quietened  (ADHS), manage to stay concentrated on therapeutic work, when sitting on the sound feel box for 20 minutes and experiencing the sound vibrations of the music Mozart, Bach or Vivaldi (CD set AMC S7). This could be achieved in a situation of a group work together with other children, what was impossible before without the stimulation of the sound feel box. (Günter Katzian)

General Information

Recent evidences from neuroscience show that sensory stimuli arising from different modalities trigger biochemical metabolic processes, activate different regions in the brain and promote the formation of the neuronal networks. The human being reacts to pressure, touch and vibration by deformation of the skin which causes the excitement of the Meissner's corpuscles, a mechano-receptor of the skin. There are up to 100.000 afferent nerve fibres which project from the sensory receptors to the central nervous system and which are distributed over the entire body surface. The vibration leads to local activation of surface-cells on the feet, hand/hands, buttocks, spine (depending on the contact) and to excitement of more depth sensitive cell-layers. Proprioreceptors located in the joints sense the position of the body, muscle tonus and depth sensitive pressure and transmit these information via the afferent nerve pathway to the brain. The brain processes all incoming sensor stimuli according to their direction, laterality, strength, and in case of music, according to its rhythm and melody. The tactile sensory stimulation is linked to the sense of hearing and the overall integration of all senses involved in the process leads to a holistic perception. Problems according to body/musle tonus are often related to auditive problems and deficits in the hearing processing.

The brain reacts to the incoming sensory stimuli caused by the vibration with spontaneous adaptation of the body/muscle tonus. The attention of the stimulated area is enhanced. The muscle tonus is regulated by the nerve pathway which projects from the spine to the periphery of the body. Vibration cause regulation. Repeated sensory stimulation causes the brain to obtain experience, to learn and adapt and in that way to improve and balance sensory regulation in everyday life.

Structure-borne sound transmitted through solid structures, such as steel and wood, is applied in different fields of therapy. Here we compare some applications with our AUDIVA concept:

AUDIVA uses special music CDs compilations.

AUDIVA uses loudspeaker (model KB 5) or a vibrator (model KB 7) applied while sitting or standing.

AUDIVA: while sitting on the soundfeelbox the user experiences the foreign voice (from CD) or the own voice (via microphone) by the vibrations.

Recommended application of the soundfeelbox

We recommend the application of the tactile-vibratory stimulation by the soundfeelbox generally for children with abnormality in their motor control as well as for adults with brain injuries.

Areas of application:

Hyperactive children, “fidgety child (fussy Philip)” are not hyperactive by purpose. They do not act ignoring and annoying wilfully. These children perceive their own body poorly and can not control their impulses. Parental instructions like “sit still” or “concentrate yourself now” has short or no effect on the child’s behaviour. Hyperactive children can learn to manage to control themselves. One very important step to achieve this is to develop good body control.

Experiencing the soundfeelbox will support your child to:

When staying on the soundfeelbox, both, the sensitivity for surface and deepness becomes conscious by the sensation of the vibration and the proprioceptive (body's own) perception is promoted.

Application of the Audiva soundfeelbox in the rehabilitation

For children who

  • have problems with the body tension (difficulties to control the body/muscle tonus).

  • show coordination problems.

  • are sensitive to excitement (react with: tactile defence, hypersensitivity)

  • are looking for strong excitement (hyposensitivity)

Possible indications

  • absent control of the body/muscle tonus, non physiological pen posture

  • midline-crossing inhibition (kinesiology) is not completed, absent bilateral integration

  • auditory processing disorder, hyperacusis

  • tactile, proprioceptive and/or vestibular deficits

  • visual deficit


  • epilepsy

  • overreaction

  • The child can not tolerate the soundfeelbox vibrations.

Possible positions on the soundfeelbox

  • standing, with socks or barefoot (to feel better the vibrations)

  • prone position, supine position

  • sitting

Duration and intensity

  • Shall be adjusted individually for every child.

  • Begin with short times, then you can slowly increase the duration and intensity of e. g. volume, rhythm, bass.

  • If tolerable, allow strong stimulation.

The sound pressure is most intensive when emitting from the low bass included in the music. The soundfeelbox transmits the sound in the range from 45 Hz (low bass) up to 5000 Hz. The sound vibration becomes more fine in the frequency range starting from 300 – 1000 Hz (middle pitch). During the stimulation with the soundfeelbox, the body awareness becomes more sensitive for this fine vibrations and in parallel the low bass signalises the rhythmic basic structure to the body.

Regular application of the soundfeelbox will lead to an alternation in the surface structure of the skin in sense of one newly purchased sensitivity of the skin receptors. The enhanced sensor system supports the motor system to balance the body/muscle tonus regulation which in turn causes better awareness for the whole body posture.

The soundfeelbox leads to new body experiences!

AUDIVA recommendations for rebalancing the body/muscle tonus by applying the soundfeelbox:

Strong body/muscle tonus


Weak body/muscle tonus

  • agitation (ADHS)

  • motor hyperactivity

← indications

  • muscle fatigue syndrome, atony

  • motor hypoactivity (ADS)

  • stress

  • excessive demand

  • loss of control

  • extraordinary strong self esteem fidgety

  • hypersensitivity to sensor stimulation


  • dreaminess

  • aversion

  • depression

  • low self-esteem

  • absent reaction of sensor signal

Calming music

slow rhythm

rebalance with music

Appropriate music will help to compensate the symptoms. You can control the feeling for rhythm and tempo by the music selection.

Please make sure that the music is generated by natural acoustic instruments.

  • Rhythmic imitation:

    • use raffles or baton

  • rhythmic body movements

Safety instructions

Please note that the application of the soundfeelbox for children occurs in the responsibility of an adult person or therapist. The stimulation intensity of the vibrations shall always be sensed by the patient as pleasant. In case the patient is not able to express her/his sensation verbally, the therapist should interpret the facial expression and movement reactions of the patient and adjust the vibration intensity to a comfortable level. Additionally the effect of the vibrations could be measured by neurofeedback.

The soundfeelbox is an electric device applied for tactile sensory stimulation without direct electric contact on the body surface. Within the scope for medical purposes, all devices connected to the soundfeelbox, such as amplifier, CD-player and other devices connected to power supply, need to obey the regulations of the standards EN 60601-1 or other appropriate standards.
