Keynote: How Sonion Is Helping the Future of Hearing Aid Technology

In this keynote talk from the COMSOL Conference 2025 Amsterdam, Michele Colloca of Sonion shares how engineers use vibroacoustics modeling and experimental tests to develop components for the hearing aid and professional audio markets.

Colloca explores how the COMSOL Multiphysics^® software helps Sonion accelerate the research and development of advanced miniature electromechanical components, such as balanced armature (BA) receivers, high-end microphones, voice pick up sensors, and hearing aids. Engineers use COMSOL Multiphysics^® to develop these components with the goal of improving transducer performance for high sound pressure levels and low total harmonic distortion.

The presentation highlights an example of the simulation of the frequency response of BA receivers that operate in multiple physics domains. Colloca then shares an example of simulating the manipulation of different transducer frequency responses with the goal of extending the transducer bandwidth. The talk concludes with an example of how Sonion uses simulation to solve the challenge of an external magnetic field causing a hearing aid or earbud to malfunction.

Michele Colloca is the head of receiver and receiver-in-canal development at Sonion, where he has worked since 2014. He holds a PhD in theoretical and applied mechanics.
