AAL’s PYOUR Audio Platform Enhanced with Addition of Aizip’s AI-Based Noise Reduction Models
Delivers cutting-edge performance in hearing aids across multiple hardware platforms
Leiden, NL and Cupertino, USA, October 14th, 2025
Absolute Audio Labs (AAL) and Aizip today announced that Aizip technology is now available as a plugin on AAL’s PYOUR Audio development framework. Prescription and OTC hearing aid manufacturers can now easily integrate cutting-edge AI-based speech / noise separation and reduction to provide significant increases in audibility in loud settings.
AI-based noise reduction has long been used in applications where extensive processing resources exist, for example in the cloud during internet meetings. Only recently has it been applied to hearing devices and even then, it has been primarily in high-end models using customized neural processors. Until today, the benefits of effective AI noise reduction have not been widely available in mid-range devices to serve the broader population of people who have difficulty understanding speech in noisy environments.
Platform Agnostic Hearing Aid Solution
AAL’s PYOUR 3.0 audio platform is highly flexible and suitable for a wide range of standard 24 bit and 32 bit SoCs. It provides superior audio, best in class speech intelligibility, and flawless wireless connectivity.
AAL’s proprietary and patented core algorithms include advanced acoustic
noise suppression, its unique iWBC (Instant Wide Band Compression) and AI-based feedback management system.
With the addition of Aizip’s tiny and highly efficient AI models into the PYOUR framework, low latency AI-based noise reduction can be implemented in the latest generation of standard chipsets that have
integrated neural network processors. In adding Aizip’s model, AAL offers manufacturers of hearing aids the ability to dramatically improve speech audibility in noise using standard silicon, without requiring a costly co-processor.
“AAL already offers a comprehensive hearing aid firmware package that brings high-end features to hearing aids using standard shipsets,” noted Nathan Francis, Head of Business Development at Aizip, adding that “together we will now set the standard for performance in accessible devices across the full range of environments people with hearing loss struggle with.”
“Speech in noise remains the key problem for people with hearing loss, often leading to social isolation when they withdraw from loud environments,” said Mark Kaal, Business Development and Innovation Director at AAL. “As the leader in the development of high performance, tiny AI models that run at the edge, Aizip challenges conventional notions about what is possible in hearing devices. We are delighted to incorporate their latest speech / noise separation models to improve the lives of millions of people who have trouble hearing in difficult situations.”
AAL and Aizip are committed to addressing the global pandemic of untreated hearing loss through the continuing development of advanced, accessible hearing aid technology. For more information, or schedule a demo at EUHA 2025, contact AAL (info@absoluteaudiolabs.com) or Aizip (info@aizip.ai).

AMADEUS: Best performing RiC hearing aid for music
Hilversum, May 11, 2023
Netherlands based audio software pioneers Absolute Audio Labs (AAL) have demonstrated in a clinical study that its Amadeus Hearing Aids are the best performing hearing aids for music streaming. The study compared 2 top models of
The setup was a double-blinded study to compare RiC hearing aids on music perception for hearing-impaired subjects. Two of the leading RiC Hearing Aids on the market for streaming of music, the Resound One and the Oticon More 1 (with the award-winning MyMusic feature), were compared to the
Amadeus, running PYOUR Audio Hearing 2.0. Twelve subjects with binaural sensorineural hearing loss were included in this study. As many as 120 fragments of various genres of music were played to each subject while switching between devices. The subjects were blind to which device they were listening to and had to indicate their preferred device after each fragment. Results showed that the hearing aid prototype of AAL performed significantly better than the other two hearing aids. The biggest differences were observed in the genres jazz and popular music. A key difference between
the AAL hearing aid and the competitor devices is that AAL includes music quality as key feature in its total design. In addition to focussing on delivering high definition and full spectrum audio, AAL uses its revolutionary and patented compression technology: instantaneous wideband compression that keeps the dynamic range of the patient intact without distorting the audio as typically happens with conventional WDRC type compression.
The principal author of the study is Kars Tjepkema, BSc as part of completing his Master Technical Medicine at the Technical University of Delft. The study was supervised by Jan de Laat PhD on behalf TU Delft/Technical Medicine and Kauê Werner M.Eng and Johannes Lyzenga PhD, both part of the AAL R&D team.
receiver-in-canal (RiC) hearing aids on preference for music streaming against the AAL Amadeus.
The Amadeus is the successor to the CES Innovation Award winning PYOUR™ Eccellenza AI premium+ and is also built on the powerful PYOUR Audio Hearing 2.0 platform of AAL.
Music enjoyment is in the DNA of Absolute Audio Labs. Since its start in 2016, AAL have released a series of products and innovations based on the PYOUR Audio platform. All of them support the important topic of restoring the music enjoyment for hearing impaired, such as the Award-winning and dedicated Parrot Zik Headphones adaptation
AAL intends to conduct more clinical studies on music and speech related comparisons as part of the development of the third generation of the PYOUR Audio Hearing platform in close collaboration with leading institutions and innovation partners and as part of an R&D project co-funded by the European Union and the “Kansen voor West” regional program.

“Music enjoyment has always been considered of minor importance by many large hearing industry players, but we believe that the introduction of the OTC hearing aid category and product launches by major audio brands like Sony and Jabra will trigger further awareness to the problem of the underwhelming performance of hearing aids for music in general” according to Aernout Arends, CEO and Founder of Absolute Audio Labs.
