Seltech also utilizes (LEM) models to design and optimize microphone channels in complex devices, effectively reducing unwanted resonances and leakages.

This approach ensures that the audio captured is clear and free from distortion or resonance. Additionally, with the widespread adoption of beamforming techniques across various industries, Seltech excels in creating and predicting the directivity patterns of different array configurations using advanced analytic methods.

Whether you aim to develop broadside, end-fire, rectangular, or circular beamformers, Seltech’s expertise guarantees optimal performance and precision in your designs. By focusing on the specific needs of your application, Seltech ensures that your microphone solutions deliver exceptional audio quality and reliability in even the most challenging acoustic environments.

Modeling
capabilities at transducer level

To further enhance audio performance, Seltech employs modeling at the transducer level, allowing for precise customization of sound signatures, especially when mechanical modifications are not feasible

At Seltech, we use the renowned COMSOL Multiphysics solution for this purpose. This advanced tool provides detailed insights into acoustic and structural behaviors, enabling us to fine-tune every aspect of the sound signature.

By leveraging these capabilities, we ensure that our clients receive speakers that are high-performing and tailor-made to their specific requirements, delivering a truly personalized audio experience.
