Reports and Proceedings

Nuheara Ltd

Nuheara Limited (ASX:NUH) (Company or Nuheara) is pleased to advise that is has successfully concluded its hearing aid clinical trial with the final report received from National Acoustic Laboratories (NAL). The clinical trial completes a very complex and important milestone for Nuheara on its pathway to an FDA 510(K) submission¹ and pending entrance into the regulated U.S. hearing aid market segment with world leading hearing aid products.

The clinical trial was conducted in Australia using Audiology best practices on participants with normal hearing and those with mild and moderate hearing loss by professional clinical Audiologists and clinical researchers at NAL. The trial successfully validated the hearing benefit of the Nuheara self-fitted hearing aids compared to unaided listening with benefits including:

  • Improved speech understanding in noise
  • Improved ability to follow conversations
  • Ability to reduce background noise levels
  • Overall hearing improvement when listening in everyday conversations

In relation to the unaided listening condition, the study data provided evidence of the superiority of Nuheara hearing aids with FOCUS enabled over unaided listening, and of substantial effectiveness of the Ear ID™ self-fitted hearing aid devices in the overall experience of listeners. Furthermore, clinical assessment showed improvement in speech understanding by 30% in noise when the Nuheara hearing aids FOCUS feature was enabled. This outcome is consistent with other studies showing advantages in speech understanding in noise with conventional directional microphones in hearing aids ranging from 25% to 30% improvement, depending on the familiarity to the speech, physical fitting, and design of the hearing aids² ᶾ.

The effectiveness of the Nuheara Ear ID™ self-fitting method was also validated, as Software in a Medical Device (SiMD), through clinical and real-world data demonstrating positive outcomes as compared to the expected NAL-NL2 clinical targets that would be performed by an audiologist fit hearing aid in a clinic.

Commenting on Nuheara’s progress in relation to its expansion plans into regulatory approved hearing aids, Co-founder, Managing Director & CEO Justin Miller said:

“This clinical study is a further critical step in the transformation of Nuheara into a medical device manufacturer of hearing aids. With the five major hearing aid companies commanding 99% of the worlds hearing aid market⁴, there are very few emerging companies who have successfully completed hearing aid clinical trials and gone on to commercialise.

“This is a pivotal development for Nuheara as we position ourselves to complete a US FDA 510(k) submission by the end of March 2022 and, pending FDA clearance, entering the U.S. regulated hearing aid market with world leading hearing aid products.”
