MEMS microphone sets new standard for AI-optimised hearing aids

Knowles Corporation launched its groundbreaking MM60 MEMS microphone at the EUHA in Nuremberg. For optimal performance of the AI chipset in a hearing aid, high-quality sound input is essential. The microphone represents a complete reimagining of hearing health technology, developed from the ground up to deliver superior electroacoustic performance and robustness specifically designed to maximise the performance for AI chipsets in hearing aid applications.

The device is constructed on two fundamental innovations: an entirely new MEMS motor and an advanced ASIC that together allow hearing aid manufacturers to meet real-world user demands without compromise. As a pioneer of MEMS microphones in hearing aids, the company has consistently delivered reliable, high-performance microphones at a fraction of the cost of electret microphones. This device continues the tradition while setting new industry benchmarks for performance, especially tailored to AI-powered hearing solutions.

The revolutionary design of the new MEMS motor offers greater reliability than currently available microphones, particularly regarding liquid and particle ingress such as water, dust, or earwax. Simultaneously, it greatly improves electroacoustic performance. The device survives 2m deep-water immersion, withstands air blasts exceeding 100 PSI, and protects against fine particles, reducing field return rates while allowing end users to maintain active lifestyles.

The advanced ASIC offers superior programmability with dual-stage gain control, precision filters ranging from 25Hz to 20kHz, DC offset alignment, and power optimisation – all factory-configured according to hearing aid manufacturer specifications. This enables more consistent results, reduces production variations, and empowers hearing aid manufacturers to leverage their AI differentiation fully features with industry-leading microphones.

For users, the benefits are clear: lower noise levels, reduced distortion, improved ultrasonic performance, and microphones that sound better and last longer in any environment, from active gym training to loud cocktail parties. The MM60 and its thinner MM61 variant are available immediately and can be integrated into new hearing systems.

"The MM60 represents a pivotal advancement in hearing health technology," said Jon Kiachian, president of MedTech and Speciality Audio at Knowles Corporation. "By combining our decades of MEMS microphone expertise with cutting-edge AI optimisation, we've created a solution that doesn't just meet today's hearing aid requirements but also enables the next generation of intelligent hearing devices. This microphone sets a new standard for what's possible when durability, performance, and AI-readiness converge in a single, breakthrough product."

With its combination of robust protection, advanced programmability, and reliable acoustic performance, the MM60 establishes a new benchmark for hearing health technology. The microphone's AI-centric design philosophy delivers industry-leading sound quality, allowing AI chipsets to perform at their best while maintaining the reliability and performance standards that hearing aid manufacturers and users demand.
