Abstract:

Single screen barriers are widely used in open-plan offices to separate individual workplaces as a means of improving acoustical privacy. Existing analytical and experimental studies show that the insertion loss of an indoor barrier is limited at low frequencies. It has been shown that active control can be used to improve the performance of outdoors noise barrier at low-frequency range. This paper investigates the feasibility of using active control system to improve the performance of the indoor barrier by simulation. The reduction of the active noise barrier in open-plan office model is almost 6-8 dB. The effect of error sensing location on the diffraction edge also be investigated. Compared with the error sensors located near the screen, when the error sensors located at far-field, the noise reduction in far-field has been significantly increased, but the near-field sound pressure level has been increased.
