RT500 Auditory integration training


RT500 Auditory Integration Training 

 

Auditory Integration Training (AIT) is a special music therapy that corrects sound processing disorders of the auditory system and stimulates brain activities by a group of filtered and modulated music, so as to treat hearing impairment, behavioral disorders and mood disorders.


 

Features

♦ Full digital touch screen operation

♦ Built-in CD image file system

♦ Multi-system signal output 

♦ Embedded Bluetooth transmission system, automatic coding

♦ Duplex radio signal output 

♦  Embedded Chinese and English operating system


Application

Pervasive developmental disorders: including autism and Asperger Syndrome

ADHD (Attention deficit hyperactivity disorders)

Speech and language development disorders

Mood disorders and affective disorders

Learning disabilities

 

Principle

1. The instrument filters out frequencies that may trigger oversensitivity, stimulates auditory cortex of the brain to reorganize, improves perception of all frequencies, and reduces distortion of audible signals.

2. It also filters out frequencies that may trigger ultra-sensitivity to reduce the sensitivity of the inner ear and/or certain areas of the brain. In this way, other parts receive stronger stimulus from sound at other frequencies. Reduction in auditory stimulus at ultrasensitive frequency can alleviate hypersensitivity and increment in auditory stimulus at non-ultrasensitive frequency can enhance perception of sound. 

3. The instrument provides collateral inhibition. When certain neurons are stimulated to produce excitement, they also exert inhibition on neighboring neurons. Therefore, the neurons at certain parts in the inner ear or brain get excited when receiving auditory stimulus at ultra-sensitive frequency, but the neighboring neurons at other parts perceiving sound at other frequencies will also get excited instead of being inhibited. Only neurons perceiving sound at over-sensitive frequency are inhibited. 

4. If middle ear muscle tone is inadequate to maintain proper function of the middle ear, auditory integration training can improve functioning and muscles of the middle ear to ensure normal muscle tone and effective sound conduction.

5. If tensor tympani muscle and skeletal muscle cannot work together, resulting in auditory reflex failure, which may easily cause middle ear damage.

6. According to the comparison of MR and PET results before and after AIT treatment, brain activities are normal after treatment, hypermetabolism of the frontal lobe is mitigated, and occipital lobe activities increase.

 

Therapeutic effect

AIT can take effect within 6 months after the treatment, and some therapeutic effects even occur during the treatment. The improved degree and aspects vary with each individual patient. 

The symptoms that can be improved after treatment are as follows:


Enhanced attention to auditory stimulus 

Enhanced memory of daily information

Enhanced speech understanding ability 

Enhanced computer ability

Extended average speech length Alleviated sound hypersensitivity

Louder voices reduced anxiety and anger

Enhanced independent living skills 

Reduced stereotyped and self-stimulating behaviors

Increased interest in communication Reduced aggressive behaviors

Increased eye contacts Reduced distraction

Increased proper social behaviors and improved adaptation to changes 

Shortened reaction time

Enhanced perception or tolerance of others' presence 

Alleviated tactile defensiveness

Increased desire to interact with others reduced echo speech
