Abstract

When exposed to noise regularly and continuously, it becomes a severe threat for the human health. Hence, the control of noise is a contemporary and widely known issue, especially in contexts of work safety in the industrial environment, but as well in the domestic field. The most common solutions are based on passive control approaches, which either involve high monetary effort (when coupled with construction actions for example) or at least require persons to wear ear protection at all time. In recent years, however, there has been a remarkable increase in the development and application of active noise control solutions. Still, the problem remains that those solutions are often tailored to a certain setting or require costly modifications of the environment. To overcome these limitations, this paper presents the concept of a position-adaptive noise control system, which aims to provide the attenuation of noise at a movable local quiet zone, that tracking the user's ears when moving within the workspace. This enables the control of noise at a spatially shifting location without any mobile devices to be carried. The application in offices or industrial settings for example - meaning in enclosed spaces - however incorporates the challenge of controlling sound in a large spatial range, influenced by reverberation. The associated need for an accurate transfer path modeling leads to the adjacent model prediction technique, presented in this paper.
