Knowles’ focus on the customer, combined with unique technology, rigorous testing and global scale, helps to deliver innovative solutions and consistently dependable and precise products.

As a Knowles team member, you are encouraged to challenge the status quo and see possibility in unexpected places. Because of our entrepreneurial culture, the only limit is your imagination. If you thrive in an agile, fast-paced and collaborative environment, you will fit right in. If you are driven by constantly redefining the gold standard of products and services that help customers, you will be a valuable member of Knowles. Let’s move ideas from concept to reality together.

The Specialty Components-Acoustics division of Knowles is the leading provider of microphones and receivers (speakers) for hearing instruments, high-end personal earphones, and ear-worn computing worldwide. The Research group of Knowles SC-A is responsible for developing the technologies to augment or even supplant the core technologies of MEMS microphones and balanced-armature receivers for improved product performance and assuring growth in this demanding, high-tech market space.

SUMMARY DESCRIPTION:
The goal of this project is to develop electroacoustic and vibromechanical models of balanced-armature receivers to assist our customers simulating hearing aid systems to optimize for acoustic output and minimize feedback due to vibration or acoustic leakage. The models are created in Mathematica by curve fitting a network model to measured performance data. The receiver models are distributed to our customers as Spice netlists, which can be imported into Modelica or COMSOL or left as an element in Spice around which the larger system can be built and simulated.

SPECIFIC DUTIES AND RESPONSIBILITIES:

Obtain representative samples of several receiver models and acquire electroacoustic and vibration performance data.
Curve-fit network models to acquired data.
Suggest and implement improvements to the data acquisition system and curve fitting software (Mathematica)
Organize and structure the resulting models as a library for distribution to customers
Perform validation testing for the vibromechanical models and discuss with customer’s engineers.
Determine canter of mass and rotational inertial of receivers in Creo
Port core data-acquisition functions from Matlab to LabView and implement function calling between LabView and Mathematica.
