Understanding the Progress Report

Sound Storm Character Melisma

What does the Progress Report show?

The progress report is presented as a graph. It is recommended that you work through this with 

your child’s clinician to best understand your child’s results.

  • The horizontal axis is the total number of games played.
  • The vertical axis is the Noise-to-Signal Ratio (NSR). This is how loud the background noise is compared to the target sound. 20dB NSR, means that your child can interpret target sounds at a level when the background noise is 20 times louder.
  • Each blue dot represents the score for one game.
  • The blue line shows the starting average for your child based on the first 10 games he or she plays. It is used to benchmark your child’s progress. 
  • The red line represents the running average of all games played to date.
  • The improvement in decibels (dB) is the difference between the running average and the starting average.

The below report is an example only. You should not compare your child’s results to this example.

What are the expected results?

In general, our research has found that children with Spatial Processing Disorder will improve by approximately 10 dB over the course of training (100–120 games). This means that, compared to before your child started training, they will be able to process a target noise – like his or her teacher’s voice – when the background noise is a lot louder.

The clinician who is monitoring your child’s progress will be able to provide feedback on how your child is progressing. It is recommended that the clinician reassess your child with the LiSN-S diagnostic test once the Sound Storm training is complete.

What is the research behind Sound Storm?

Research documenting the development and evaluation of Sound Storm (previously known as the LiSN & Learn Auditory Training Software) has been published in peer-reviewed journals and textbooks. A list of these publications can be found in ‘The Evidence’ section on this website.

Training modules for clinicians can be found at the HEARnet Learning website at

Who is a good candidate for Sound Storm?

Before using Sound Storm, it is essential to establish that a child has:

  • Hearing within normal limits.
  • A diagnosis of Spatial Processing Disorder. If they do not, you won’t know if you are targeting the right deficit with Sound Storm.

Sound Storm has been clinically proven to remediate Spatial Processing Disorder in Children aged 6 - 12yrs. Children younger than 6 are too young to be diagnosed with Spatial Processing Disorder and are unlikely to maintain the attention needed to complete the training.

Children over 12 are less likely to find the app engaging, and would need to be highly motivated to complete the training. If they do complete the program however, it may still be effective.

While there have been no clinical trials carried out on ages above 12, there is anecdotal evidence that suggests that Sound Storm is likely to remediate Spatial Processing Disorder in adults as well as children over the age of 12.
