Feedback and Noise Cancellation

Audio algorithms are as diverse as they come. Just within Cancellation one could get lost in the myriads of algorithm candy land for the most varied use cases and applications. Join us in this webinar to hear some of the latest exciting research in the cancellation realm, be that feedback, environmental noise or other noises that must be removed from the desired sonic result.

There are several use cases and applications of which removing/ cancelling sound is necessary. A good example is the now famous active noise cancellation, of which microphones and speakers are used as signals into an algorithm to reduce the background noise from headphone use. In a completely different algorithmic manner, feedback cancelation is a must-have algorithm for hearing aids due to the fact that hearing speaker must play and massively amplify whatever the microphones are listening to – plus, the distance between them is nothing, they are so close! In this webinar we decided to combine different types of cancellation algorithms and share the latest news and research in the cancellation(s) realm.

Meng Guo, Principal Researcher at Demant

Dr. Meng Guo received the M.Sc. degree in applied mathematics from the Technical University of Denmark, Lyngby, Denmark, in 2006, and the Ph.D. degree in signal processing from Aalborg University, Aalborg, Denmark, in 2013. From 2007 to 2010, he was with Oticon A/S, Smørum, Denmark, as a research and development engineer working with acoustic signal processing. Currently, he is with Demant A/S, Smørum, Denmark, as a principal research engineer. His focus is on product‐oriented research, in the areas of acoustic signal processing and machine learning for hearing aid applications and wearable healthcare technology.

Franz Heuchel, Postdoctoral Researcher at DTU

Franz Heuchel is a postdoctoral researcher at the Acoustic Technology Section of the Technical University of Denmark. His research focuses on the intersection between acoustics and control, particularly on modelling and compensating for nonlinear distortion in loudspeakers and actively controlling sound fields both indoors and outdoors.
