Performance Evaluation of Active Windows Using Speech Intelligibility

Abstract

Abstract-This paper presents an experimental work on the performance assessment of windows equipped with the active noise control technology. Recently, several active windows have been studied and proved to reduce the transmitted exterior noise through an open window. However, the performance of the systems has been evaluated only in terms of the sound pressure level or the power spectrum. In this paper, the speech intelligibility is adopted to assess the performance of the active windows for more practical measurements. The results of scale-model experiments show that the active window can improve the intelligibility as well as reduce the noise level.
