- Zone separation control to improve reproducibility of broadband sound
説明
<p>This paper deals with the problem of separating a single broadband sound into audible and inaudible zones in the same space. In a previous study, a method for designing a control filter to control a broadband sound was proposed. However, the frequency response of the control filter obtained by ACC is not optimal, since it is only a simple arrangement of the sound source outputs obtained independently at each frequency. Therefore, we focused on the frequency response of the amplitude of the control filter and introduced the amplitude coefficient that would determine the relevance of each frequency. This is determined by specifying one control point in the audible zone and calculating the ratio between the signal without control and the signal obtained by ACC at that point. Using the amplitude coefficient appropriately adjusted the filter coefficients of the control filter and it is shown that the reproducibility of sound is improved.</p>
