Project #113: Development of an analog-based noise-cancelling headphone for use in aircraft passenger cabins

Back

Description:

Headphones currently supplied to economy-class passengers in aircraft are very low cost, but typically do not incorporate noise-cancelling capability. This project will continue the work of a project group last year that looked at the development of a low-cost analog-based noise cancelling technology for use in such headphones, the primary goal being to attenuate cabin noise. Last year’s group produced an excellent design that, on the basis of simulation, appeared to work very well. But they could not complete the hardware implementation and testing of a prototype. The goal for this year is to complete this phase, consider strategies for optimizing performance, and then, time permitting, look at how the design could be miniaturized.

Outcome:

Functioning set of headphones
