 AIT Helps Improve the Lives and Learning of Those with Autism, ADHD, Hyperacute Hearing, Speech Delays & 10 Days.

The AIT Institute is the #1 Provider off AIT At Home Services globally and is the largest AIT resource website in the world.

AIT is the #1 clinically studied auditory based educational intervention!  All sessions are conveniently completed at home under the supervision of an AIT Practitioner. AIT services are available in the USA, Canada and other English speaking countries.

AIT requires 10 hours of sound therapy, with 20 sessions of 30 minutes each, done 2 times daily over 10 consecutive days.  This listening therapy helps to correct hyperacute hearing,  tinnitus and other auditory challenges.

AIT has been used successfully with children and adults with many different diagnoses for over 60 years.  

Remarkable results are achieved for many families. There are more than 60+ years of clinical research and 28+ scientific studies on AIT.

How Does The Filtered Sound Training System (FST) for AIT Work?
When an individual listens to music from the FST or PortaFST Systems, the muscles in the middle ear shift and readjust continually in response to the modulated tones. This continual movement of the muscles in the middle ear becomes an exercise that strengthens the ears ability to modulate sound. Read more about AIT and the Brain and well as clinical studies on AIT.

What Does AIT Do?
As the result of research, it is shown that
the cochlea experiences a ‘wash’ of fluid back and forth as well. The net positive effect is that the middle, and to some extent the inner ear, receive the equivalent of a massage that allows for greater flexibility and responsiveness to sound stimuli. Auditory information from the ears is processed by the temporal lobe of the brain, which is also heavily involved in the processing of language-based information and has some role in emotional functioning. 

This is why AIT can benefit those with speech delay, stuttering and other speech issues.

There is clinical evidence that AIT involves remapping of areas of the brain associated with auditory processing and that the temporal lobe stimulation encourages the development of new dendritic branching. Ongoing research will come to reveal more clearly how the kinds of changes practitioners regularly report are brought about.

Development Of Filtered Sound Training (FST)
FST is an new and updated adaptation of the internationally known system of Berard Auditory Integration Training (AIT). This new development has been made possible through the combined expertise of the team at Dataworks, Waterford, in Ireland and Rosalie Seymour, AIT Practitioner and Professional Seminar Trainer who was certified by Dr. Berard in 1994.


Doing AIT using the FST or PortaFST Systems is different in many respects from other types of auditory techniques:

  1. It uses high energy styles of music.

  2. It uses music with vocals to maximize the impact on the auditory system for more benefits.

  3. It helps to exercise the listening mechanism,  not stimulate the emotional state.

  4. The AIT Protocol that is followed is exactly the same: The duration is specifically two (2) half-hours per day for ten (10) days consecutively or with a maximum two (2) day pause after the first five (5) consecutive days. The minimum time between AIT sessions in a day is 3 hours.

  5. The volume settings, which are as intense as the user can tolerate, to give maximum ‘exercise’, within approved hearing safety limits.

  6. AIT if repeated is not done more frequently than once a year and is only repeated if needed.

  7. AIT gains are often immediately seen, develop over time and are long lasting.

Comparison Filtered Sound Training (FST) System Compared To Other AIT Devices

Former AIT devices in use including the Earducator, Digital Auditory Aerobics (DAA) and Audiokinetron (no longer manufactured) all have from the same drawbacks in AIT delivery:

  1. First, they are more expensive for a Practitioner and also a Client who is supervised in office with the Practitioner, for 20 sessions of AIT.

  2. Secondly, they are bulky devices.

  3. The client must travel to the office of the AIT Practitioner to access the AIT device in order to obtain the 10 - 12 days Auditory Integration Training 20 session protocol.

Benefits of Filtered Sound Training (FST) System Compared To Other AIT Devices

  • The FST is a new concept in AIT that runs from a PC or laptop, using the sound manipulation capabilities of the PC with the control for levels of loudness, filters and session timing being built-in to the FST program.

  • FST has been developed to answer the need for greater accessibility and lower costs.

  • FST is software based and utilizes PC technology and your own computer system to deliver high quality supervised At Home AIT in the home, office or school.

  • The FST System will deliver the AIT-quality sound alternation via headphones and adheres to the original specifications of Dr. Berard with one very important difference - that it can be done in the client’s home!

  • FST remains free of the unproven restrictions regarding minimum age of training and  the complicated filtering protocols of older AIT equipment.

  • For children with autism or under age 6, no Audiograms or Listening Tests are required making AIT easier, less expensive and still as clinically effective.

  • Older equipment has been inconvenient to families seeking AIT for their children or an adult with a busy work schedule.

  • This restriction, together with the expensive equipment needed, has tended to limit the availability of AIT.

  • The FST Practitioner License provides the AIT Practitioner an unlimited license that replaces the more bulky and costly hardware traditionally used for AIT.  

  • Certified AIT Practitioners in the FST system can adjust settings for individual users who attend the AIT sessions in the usual manner of AIT.

  • FST is an unlimited license, allowing multiple applications from one system.
