Abstract EN
An active noise control scenario of simple ducts is considered.
The previously suggested technique of using an single loudspeaker and its rear sound to cancel the upstream sound is further examined and compared to the bidirectional solution in order to give theoretical proof of its advantage.
Firstly, a model with a new approach for taking damping effects into account is derived based on the electrical transmission line theory.
By comparison with the old model, the new approach is validated, and occurring differences are discussed.
Moreover, a numerical application with the consideration of damping is implemented for confirmation.
The influence of the rear sound strength on the feedback-path system is investigated, and the optimal condition is determined.
Finally, it is proven that the proposed source has an advantage of an extended phase lag and a time delay in the feedback-path system by both frequency-response analysis and numerical calculation of the time response.
