NewSound has rolled out a fresh series of over-the-counter (OTC) hearing aids in March 2025, as shared in an official news release on BusinessWire. These new devices use the Femtosense Sparse Processing Unit 001 (SPU-001) technology, which enhances speech on the device itself through AI-driven noise reduction. This innovation aims to boost sound clarity without needing cloud processing.

Enhanced Technology Features

The SPU-001 chip, engineered by Femtosense in California, utilizes sparse neural networks for real-time audio improvements while conserving energy. NewSound claims that its hearing aids adjust dynamically to various challenging sound settings, like busy places or city sounds, to enhance understanding of speech. The American Speech-Language-Hearing Association (ASHA) states that many individuals with mild to moderate hearing loss struggle to hear well in noisy situations.

Market Growth Predictions

A report from MarketsandMarkets in 2024 anticipates that the worldwide ear health market, which encompasses hearing aids, is set to rise from USD 1.4 billion in 2021 to USD 1.9 billion by 2026, achieving a compound annual growth rate (CAGR) of 6.3%.

With a focus on on-device processing, these new devices are designed to tackle privacy and delay issues often linked to cloud-based AI solutions. NewSound promotes these models as OTC hearing aids, typically suited for those with mild to moderate hearing loss, and emphasizes their availability through OTC outlets. This strategy aligns with the overall trend in the industry towards making hearing technology more accessible.

Independent Reviews Still Pending

As of now, there have been no independent assessments regarding the performance of these devices.
