Noise Cancelling Audio System Design
Budget: €36 – €0 EUR
I require an acoustic engineer with experience in the design and implementation of active noise cancelling audio systems. The system will be embedded within a medium-sized, desktop or portable product, and will be solely powered by a plug-in/AC power source.
The key skills and experience required are as follows:
- Proven track record in acoustic engineering, particularly related to active noise cancelling systems
- Experience in designing audio systems for integration into other products
- Experience in maximizing the signal to noise ration for microphone and selecting best speakers
- Ability to work within size constraints
The job will mainly revolve around evaluating our selection of microphone, speakers, optimizing their number and position.
We already got a full DSP system developed as proof of concept together with code, and we have causality and coherence, but not enough attenuation, we think that we now need to improve the acoustics of the system, in particular the sensitivity of the microphone and the response of the speaker.
As the system is immersed in an airflow (1 m/s) , all possible countermeasures to avoid turbulance affecting the microphone signal will be needed.
Previous experience in active noise cancelling acoustic design must be provided.
Your challenge will be to create a highly effective audio system (reference microphone, error microphone and speakers) for an active noise cancellation system.
