The TFH Vibroacoustic Resonator Unit is the controller at the heart of the TFH Somacoustic system - the piece that brings every TFH vibroacoustic therapy product to life across Canada and the US. Without it, the Somacoustic furniture is silent. With it, the body becomes the instrument.

Vibroacoustic therapy works by passing pure low-frequency sound vibrations directly into the body through embedded resonators in the furniture - not filling the room with music, but transmitting it into muscle and bone at a cellular level. The human body is over 70% water, and sound travels five times more efficiently through water than through air. What the ear hears as muffled bass, the body experiences as deep, resonant vibration. The Resonator Unit - also known as the Somacoustic Controller - is calibrated to deliver frequencies in the 20 to 100 Hz range, the band considered most therapeutically effective for body-level sensation. At 40 Hz, brainwaves associated with movement begin to respond. At this cellular level, the therapy is felt in a way that is difficult to describe to someone who has not experienced it, and almost immediately recognisable to someone who has.

Key Features of the TFH Vibroacoustic Resonator Unit

• Connects Up to 2 Somacoustic Products Simultaneously - Two TFH vibroacoustic furniture pieces can be connected to a single Resonator Unit, making it practical and economical for therapy rooms, sensory classrooms, and clinical settings that use more than one piece
• Connects Up to 2 Speaker Boxes - Optional speaker boxes can be added so the room fills with music alongside the body vibration, offering a layered multi-sensory experience that combines auditory and somatic input
• Bluetooth Wireless Music Input - Connects wirelessly to any phone, tablet, or Bluetooth-enabled device, allowing therapists and caregivers to stream music from any source without cables or proximity requirements
• CD Player Input - A dedicated CD input means the controller works with physical music libraries, which remains relevant in many clinical and residential settings where device access is limited
• Memory Stick (USB) Input - A USB port allows pre-loaded playlists to be played directly from a memory stick, removing the need for a connected device during sessions
• Independent Volume and Vibration Controls - Separate control knobs govern the vibration intensity and the audio volume independently, so the depth of somatic vibration can be maximised while keeping room volume low - a critical feature in shared sensory spaces and clinical environments
• Thermal Safety Switch - A built-in thermal overload switch shuts the unit off temporarily if it overheats, protecting both the equipment and the connected furniture from damage during extended use
• Compatible Exclusively with TFH Somacoustic Products - The Resonator Unit is engineered specifically for the TFH Somacoustic range; using any other amplifier with TFH vibroacoustic furniture will damage the internal resonance pods and void the warranty

The Science Behind Vibroacoustic Therapy

Vibroacoustic therapy was developed in Norway by Olav Skille in the 1980s as a way of transmitting pure sine wave vibrations into the body through embedded low-frequency transducers. The U.S. Food and Drug Administration has approved vibroacoustic therapy for increasing circulation, relief from pain, and improving mobility. Research is ongoing into applications for fibromyalgia, cerebral palsy, and Alzheimer's disease. The modality has been used in hospitals, rehabilitation centres, palliative care settings, and sensory rooms worldwide.

For OTs and allied health professionals, the Resonator Unit is the essential bridge between the intent of the therapy and the body of the person receiving it. Vibration intensity is controlled entirely through music choice and bass selection - calmer music with lower bass delivers gentle, grounding proprioceptive input, while more rhythmic, bass-forward selections produce stronger, more alerting vibrations. This makes the TFH Somacoustic system fully adaptable to the individual sensory profile of any user.

Please note: because the primary purpose of this system is vibration rather than sound reproduction, music will be intentionally muffled during use. This is a therapeutic vibration system, not a speaker or audio system.

Ideal For

• Occupational therapists and allied health professionals building or outfitting vibroacoustic therapy rooms
• Schools, special education programmes, and sensory integration classrooms
• Children's hospitals, rehabilitation centres, palliative care, and residential facilities
• Adults and children of all ages and abilities who benefit from deep proprioceptive and calming sensory input
• Any setting where TFH Somacoustic vibroacoustic furniture is already installed and a controller is needed to activate it
• Families building home sensory environments incorporating TFH vibroacoustic products
