FST is a method, supported by multiple research studies, that uses music to re-train listening skills by filtering the sound in a specialised way. The training is offered in a personalised package of 20 half-hour sessions, done twice a day consecutively for 10 days. Changes that occur in listening and learning are seen over the period of 4 months following FST. FST/AIT is a non-medical approach that often has far-reaching benefits.


Filtered Sound Training is beneficial for the individuals who present with the following challenges: hearing problems, dyslexia, Autism, painful hearing, ADD, ADHD, language delay, Down syndrome, Central Auditory Processing Disorder, sensory integration problems, balance and laterality problems.


The benefits of this ten-day training course tend to vary from person to person. The most frequent improvements seen are: listening and responsiveness, improved attention and memory, better awareness of the environment, social responsiveness, improved communication and language, improved sensory processing, better bilateral coordination.


Filtered Sound Training can be combined with any therapy. But if your child is receiving Neurodevelopmental RMTi Reflex Integration therapy, it would be best not to do RMTi for the 10 days of FST since both interventions stimulate the vestibular system and it might be too much for the child to integrate. Our best practice protocol is to offer FST first and then to continue with RMT after the 10 days.


The same protocol applies to combining ABA therapy with FST – even though ABA doesn’t stimulate the vestibular system, but because some children may feel tired from the FST, doing both interventions at the same time might be too much.  It’s advisable that your child always does only FST for the 10 days, and then continue with other therapies. Any intervention that requires the use of headphones or earphones should be avoided or done before FST.
