Title: Udo Zoelzer: Innovator in Noise Cancellation Technology

Introduction

Udo Zoelzer is a notable inventor based in Neu Wulmstorf, Germany. He has made significant contributions to the field of noise cancellation technology, holding 2 patents that showcase his innovative approach to reducing unwanted noise.

Latest Patents

One of his latest patents is an active noise cancellation system designed to reduce unwanted noise in a target area. This system works by attenuating a disturbance noise signal, which is the remaining noise in the target area that originates from an ambient noise signal present in the vicinity. The system includes a processing unit that implements an ANC-controller, providing a control signal to a speaker in the target area to generate an acoustic signal that destructively overlaps with the disturbance noise signal, thereby attenuating it. Another significant patent involves a compander that uses adaptive pre-emphasis filtering based on linear prediction. This invention includes a compressor device with a level detecting/control device and a pre-emphasis device for adaptive filtering, as well as an expander device for de-emphasis filtering.
