Irritable Bowel Syndrome (IBS) is a perplexing and persistent problem affecting 11 per cent of the world’s population.

IBS has a significant impact on the quality of life of up to 1 in 5 Australians, meaning that someone close to you today is likely to be affected by this recurring and gut disorder. The current diagnostic process is time-consuming, costly and elusive, unnecessarily clogging up our health system.

Patients are typically referred to a specialised to undergo a colonoscopy to exclude all other gut disorders. This means that many patients undergoing one of the 900,000 colonoscopies performed in Australia each year do so for no reason.

The Noisy Guts Project is the brainchild of Professor Barry Marshall. Our solution is an acoustic belt that listens, records and analyses gut noises. We use existing and proven acoustic sensing technology initially designed to pick up the sounds of termites.

Our research shows a strong correlation between gut noises and gut disorders. Our product capitalises on today’s trend of wearable technology and is supported by a smartphone app that records symptoms. Our acoustic belt works similarly to the way in which an ECG monitors your heart rate. The end result is a safe, non-invasive screening, monitoring and diagnostic tool.

Noisy Guts: treating Irritable Bowel Syndrome

Noisy Guts in action

Thanks to The McCusker Charitable Foundation, the Noisy Guts Project has made great progress toward using bowel sounds to diagnose and monitor common gut disorders such as Irritable Bowel Syndrome. Our preliminary studies have achieved promising results and we can currently diagnose IBS with 87% accuracy.

Recent highlights:

  • presented our initial results data at the world's premier gastrointestinal conference in Chicago in June 2018
  • submitted 6 peer-reviewed journal publications
  • secured 1 PCT and submitted 2 patent applications
  • conducted 140+ customer discovery interviews with key stakeholders to understand the lived experience of IBS patients 
  • created a library of over 300 recordings
  • undertook commercialisation training with CSIRO ON Prime & ON Accelerate, Ignition and Start Something
  • built our media profile, including securing an audience of over 1 million viewers for a segment on Channel 7s Today Tonight
