How do iLs work?

iLs founders, after many years of collecting feedback and refining their auditory program, decided to take the next step and develop a multi-sensory method that would be more effective than sound alone-- a program that combined a customizable auditory program with visual, vestibular, and movement activities.  The method is based on the premise that specific, simultaneous sen and repeated stimulation will gradually train the brain to process the sensory input more effectively. iLs-Associates have since found that;

1) the combined therapy is greater than the sum of the parts ( ie. there is an exponential effect ) and 

2) not only does processing ability improve but motor skills and emotional regulation are also positively affected.

While clinical evidence is often enough to show that a particular therapy works, it is a monumental bonus when the mainstream scientific community decides to agree on a term that supports clinical results. The term "neuroplasticity" refers to the brain's ability to grow and reorganize itself by producing new neurons and forming new neural connections throughout life. This means that the neurons (nerve cells) in the brain change their structure through increased branching and form numerous new connections in response to new situations or to changes in their environment. These findings extend to all input, including sound. Neuroplasticity was just reaching the tipping point of scientific acceptance when iLs was formed in 2007. The book "The Brain that Changes Itself," hit the NY Times bestseller list in 2008, and the notion that the brain can actually be rewired - through specific, simultaneous, and repeated stimulation - was no longer a "fringe" concept. The phrase that is now accepted by neuroscientists worldwide (Known as Hebb's Law), "neurons that fire together, wire together," could just as well be the maxim for iLs.

iLs programs effectively "re-train" parts of the brain involved in learning, communicating and moving. Combining an auditory program with specific visual and balance activities, iLs strengthens neurological pathways and improves our ability to learn and to process information.

 The three main systems for organizing sensory input - visual, auditory, and balance (vestibular) - are highly interrelated. Exercising all three simultaneously is a holistic approach that can help people of any age feel sharper, more focused, and self-confident.

Dr. Alfred Tomatis was the first to recognize the relationship between the ear and the voice through a cybernetic, or feedback, loop ( know as the Tomatis Effect ). Given his work on the ear/voice connection, Dr. Tomatis became extremely well known for his ability to help musicians, singers and actors with their musical and vocal productions. 

The Third Law:

The third law expresses as follows: Sufficient auditory stimulation will provide a lasting improvement in the ability to listen and consequently, improvement in the reproduction of sound.

The third law,also referred to as the 'Law of Retentivity', emphasizes the permanent and lasting effect on the voice when the frequencies of the ear restored. It was through the application of this third law that Dr. Tomatis also began his work on improving foreign language integration and reduction of foreign accents. Dr. Tomatis wrote:

"Once an individual is able to accurately hear the sounds of another language and this listening ability is imposed on the individual through the electronic ear, the individual over time and practice of his own vocal emissions is able to retain and repeat those foreign language sounds with a minimal accent"

This third law, therefore finds a broad application in the domain of what Dr. Tomatis calls "the integration of living languages". 


Who can benefit?

iLs programs directly affect our sensory systems, thereby influencing a broad spectrum of our day-to-day functions. iLs is most often used to improve the following concerns:


Other areas where iLs are successful include the recovery of executive functions after head injuries, improving emotional well-being, and helping children on the autistic spectrum.


iLs Intensive Program ( using the Pro set )

We provide the the Intensive  Program  ( Pro Set ) and SSP  at our clinical Bavx  Center.

This Intensive Program varies from 30 - 120   sessions in length. Sessions are typically 60-80  minutes each, with a frequency schedule of 3 to 5 times a week or daily during the school holidays .. 


What can I do while listening?

Kids do a lot of activities for Gross Motor Activities together with fine motor activities while they are doing their listening. times are also spent standing on the Balance Board doing eye-hand coordination activities and Bal-A-Vis-X. Climbing the indoor rock wall and are also included.

The remaining listening time is for quiet activities such as drawing, puzzles, playing cards, fine motor games, and/or light exercise such as walking or stretching.


Preliminary Research

iLs continues to gather data supporting the empirical results we see daily in clinics and schools. To date, university research and third party data show efficacy in areas of:


  • Reading -- data shows students' reading ability improving by an average of about 2 years after a 3-month iLs program.

  • Auditory Processing -- improvement occurs across the entire range of auditory processing skills, especially in areas of auditory figure-ground, auditory memory, dichotic listening, and binaural summation.

  • Attention -- school data consistently report significant improvement in attention as well as behavior.

  • Evidence-Based -- iLs professional and home systems employ music processing techniques proven over decades.

What is SSP?

The Safe and Sound Protocol is intended to accelerate the effectiveness of other modalities by preparing the client's emotional and physiological state. Dr. Porges discusses two passive pathways to achieving progress with clients; the pathway and the active pathways. Since a calm autonomic/physiological state is necessary for health, growth, and restoration achieving it becomes the foundation of effective therapy. We conceive of the SSP as a passive pathway therapy helping to change the client’s physiologic state through neuroception and opening the system to further neural change from other active pathway therapies that follow.

In the case of iLs, the Focus Programs are active pathways therapies where the consistent attention to the music and movement engages and exercises the social engagement system and can create and secure neuroplastic change.

The SSP is backed by twenty years of clinical trials and peer-reviewed, published research.


SSP (Safe & Sound Protocol)

 Developed by Dr. Stephen Porges, the SSP is a five-hour auditory intervention designed to reduce stress and auditing sensitivity while enhancing social engagement and resilience. The intervention uses prosodic vocal music that has been filtered to train the middle ear muscles to focus in on the frequency envelope of human speech. Once the human speech is properly perceived, the portal of social engagement has been opened. You will find you are (or your child is) better able to interpret not only the meaning but the intent in conversations. And the sense of safety that is achieved by better understanding the fluctuations in a human voice, calms (or your child's) physiological state. Once your system has been primed and your state is calmed, further therapies are enhanced and behavioral regulation is improved.


 The Science Behind It

      By exercising the middle ear muscles, the intervention helps the muscles regulate which frequencies can reach the brain.

  • When only very low frequencies are allowed to pass, individuals tend to feel anxious or hyper-vigilant.
  • When very low frequencies are successfully filtered out, individuals can focus on the frequencies related to the human voice.


Characteristic of Potential Clients:

Individuals who have difficulty with behavioral, autonomic state regulation.


The intervention targets specific features such as:

  • Auditory Hypersensitivity
  • Difficulties with auditory processing (listening, following verbal commands, speech-language delays)
  • Behavioral outbursts (difficulties in behavioral state regulation, hypervigilant, distractible, impulsive meltdowns, hyperarousal)
  • Inability to focus or sit still.
  • Anxiety in social engagement
  • Poor eye contact and difficulties in social engagement.
  • Blunted facial expressivity.

  3. Each child is required to do a physical check on the ears prior to the SSP
  4. The session is one on one. 
  5. The session will be carried out only if the child is well.
  6. Must fulfill the Trace Together Check-In on each day of the listening.
  7. Contact Sumi to confirm your slot/payment.
  8. Reschedule if the child is unwell on the day of listening.
  9. Come on time accordingly to your schedule.

Reducing Auditory Hypersensitivities in Autistic Spectrum Disorder

In this peer-reviewed study, children with Autistic Spectrum Disorder (ASD) who used an early version of SSP experienced significant improvements in behavioural organization, listening, spontaneous speech and hearing sensitivities.

Two trials validated these findings. The first tested the difference between receiving the intervention while playing calmly and simply wearing the headphones (with no sound or music). The second tested the difference between using the intervention with the specially treated music and with intreated music. Despite being "blind" to which group their child was in, parents of the children who received the full intervention in each trial reported significant improvements in the domains of hearing sensitivities and emotional control.

Testimonial of SSP & ILS

Is a blessing in disguise, due to covid we are not able to travel and is a school holiday, hence, we have a more flexible schedule to enroll Ernest in this program to give it a try. Thanks to Kak Sumi for her passion and sincerely wanted to see the children benefit from their full potential, her center is biogeometry harmonized and she integrated brain gym, BAVX, involved the children in educational games activities like puzzles, Blockus, marbles, etc. My son, Ernest benefit so much from this program that he managed to overcome his fear of height and able to climb, which he enjoyed doing it now. He is also able to cycle on 2 wheels (to some children, is easy but to Ernest is a big milestone). I’m so happy for him. 2 weeks after he can cycle, he joined Kak Sumi outing, cycle from Bedok Reservoir to East Coast Park via the NCP ( Park Connector )  without complaints. We are so proud of him. I believe all these achievements are just beginning for him, I’m looking forward to more surprises in the next few months. 

Last but not least, Kak Sumi, I’m so grateful for your help and bringing this program to Singapore

iLs Testimonial – Sammy, 6yrs old. ( PDD NOS )

May 2018

Our son started the program sometime in March 2018 and by God’s will, we managed to complete all 30 session by early May 2018.

About four years ago, our child was diagnosed as PDD NOS and that he was non verbal til couple of years ago. Our son, much like any other spectrum child out there, had many sensory issues (afraid of height, balance issues, repetitive movements, stimmings, some tactile sensitivities, and etc) which made him scared of pretty much a lot of things. Much therapies were done for him with decent progresses but it felt like we were missing something. End of 2017, we got to know this iLs program and felt like it could feel the gap for him. We then decided to go for it in March 2018.

In such a short period of time, the progress had been tremendous and it was as if our child was reborn into a new person. The things he did not dare to do or even try; the endurance and motivation we did not know it existed in him; the abilities and talents he had them in him, all just surfaced during the program.. and even after completing the program, we still find new positive changes from him.

 Among the positive changes we experience, the highlight of it would be meltdown recovery time and lesser tantrums. Our child had become very cooperative when the turn of the event not to his favor.. and the meltdown, we think it was gone just like that. Usually would take 15-30 minutes to calm him down from the meltdown but we noticed after around 20 some sessions, could have been sooner (we was not aware by accident), our child just acted properly without ANY meltdown. We believe it was the program which helped this part for our child. The best thing was, we never even expected this to happen... what a pleasant surprise and it was a very very emotional moment for us when we discover that.

We are very grateful to have had the opportunity to experience such powerful program for our child. Asides from the program, we also believe that Sumi held major role on the successful completion of the program. Not only she customized the best according to the child’s needs, she was very compassionate and extremely knowledgable in what she was doing. Knowing exactly what was going on with our child and putting together a very long program for him, it was not a simple task. Not only we owe it to the creator of iLs but we are also indebted with Sumi for showing the path and leading us to a new bright chapter in life. Thank you Sumi, Hadi, and BrainGym Playhouse of Singapore. May God blesses you for everything you have done for us
