We recommend the advanced Waves Multi-Sensory Air and Bone Conduction Headphones and Amplifier.

TLP is enhanced with the addition of bone conduction technology. This technology takes TLP to a higher level of effectiveness. It combines the experience of listening to music through modified headphones adding subtle, synchronized acoustic vibration of the skin and skeletal system, engaging the whole body and brain in the listening process. This multi-sensory approach accelerates and expands the benefits of The Listening Program.

Bone Conduction Applications

Most listeners of all ages will achieve faster results with The Listening Program® with the addition of bone conduction technology.

Following is a list of circumstances that would indicate the use of TLP with bone conduction technology:

• History of ear infections

• Hearing loss

• Autism Spectrum

• Sensory Processing

• Over or Under arousal

• Poor Self-Regulation

• Anxiety

• Sound Sensitivities

• Difficulty filtering background noise

• Poor body awareness

• Gravitational insecurity

• Poor posture

• Balance problems

• Low muscle tone

• Poor coordination

• Poor spatial awareness

• Expressive speech and language issues

Waves Bone Conduction System

Waves is comprised of a small, custom made, pocket sized, amplifier and specialised, open-air headphones that include a bone conduction transducer in the headband.

The first-generation Bone Conduction System was released in April 2007.

Theory on the Physiology of Bone Conduction

How does the addition of listening through bone conduction simultaneously with air conduction have the calming effects observed? If we consider anatomy, the inner ear resides within the petrous portion of the temporal bone which angles forward at about a 45-degree angle ending near the foramen magnum near the midline. This means the left and right inner ears are quite close to one another. Housed within this bony chamber is the membranous labyrinth that contains the cochlea and the vestibule. The vestibular system includes the three semicircular canals that provide information on rotation and dynamic movement of the head and the saccule and utricule that give the brain information on the effects of gravity and acceleration and deceleration.

Vibration of the bone is transmitted into the fluid medium of the vestibular system causing the hair cells to move in response to agitation of the calcium deposits in the macula of the utricle and saccule. The movement of the hair cells causes an electrical discharge to occur which is carried to the cerebellum, the basal ganglia and to the cortex of the brain. Through rich connections between the ear’s vestibular system, cerebellar pathways and the body’s muscles and joints, awareness of our body at a conscious and deep subconscious level is enhanced. This is the infrastructure of our ‘psyche’ or body awareness, the organizations of which is the foundation for higher learning and integration. The input from the vestibular system to the brain also charges the brain with energy at sub-cortical and cortical levels, leading to a deeper somatic awareness of ourselves as well as improved focus and attention due to this added energy input. In essence, the bone conduction through the vestibular system is grounding, meaning that we feel connected mind to body and to gravity. There is improved ability to execute the motor activities required for success in the world; be it in sports, dance, handwriting or riding a bicycle. Once the conscious attention can be freed up by making the regulation of our body movements automatic, attention can now be directed to taking on the challenges of learning, regulating our emotions, and developing the executive functions of organization, planning and impulse control.

Much of what has been described above is attributable to both air conduction and bone conduction. However, bone conduction is an added form of stimulation to the vestibular system that is stronger than air conduction alone and is particularly helpful in dealing with issues related to balance, fine and gross motor development and speech and language control. The increased input to the cortex of the brain may accelerate the maturation of the brain as well. Therefore, along with the improvements observed in balance and motor control are improvements in emotional control with reduced anxiety, fewer melt downs, less anger, crying spells and a better adjustment to the listening process.

The vagus nerve, the 10th cranial nerve, sends branches to the external surface of the eardrum and external acoustic meatus. Thus we reach out to our environment to get a “gut sense” so to speak, and to test the reliability of what we hear against our inner awareness. Stimulation of the vagus nerve also stimulates the parasympathetic nervous system, the homeostatic branch of the autonomic nervous system. This stimulation provides another level of calming influence to that provided by the bone conduction.

We listen to ourselves through bone conduction and to others through the air. If you have ever listened to a recording of your own voice you have experienced this phenomenon. Bone conduction tends to amplify low frequencies, so most people hear their own voice as being of a lower pitch than it actually is.

As we speak our entire body resonates due in part to the speed in which sound travels through bone. Our self perception through speech is primarily through the influence of the bone conduction pathway. This is quite different from how we listen to others, whose voices are transmitted through the air.

When the body and brain are stimulated with simultaneous acoustic and somatosensory stimulation, the limbic system is engaged. With the numerous cortical and subcortical brain structures that are part of the limbic system it becomes easy to understand what a profound influence bone conduction technology can have when used with The Listening Program. The whole body becomes engaged with listening, connecting mind and body with profound influence.

The advanced Waves Multi-Sensory Air and Bone Conduction Headphones and Amplifier are $1875. Alternatively, basic air conduction headphones are typically around $250.
