有源噪声控制已应用于各种系统，以便在不增加传统无源噪声控制处理所需的尺寸和重量的情况下提高性能。本文研究了主动噪声控制系统在豪华游艇主舱发电机噪声控制中的应用。研究了游艇主舱内采用扬声器和麦克风的多通道、多音调主动噪声控制系统。结果表明，由于发电机产生大量发动机指令，为了实现显着可感知的噪声衰减水平，有必要控制至少 7 个单独的指令。研究了以 19 个发动机指令为目标的控制器，结果表明它可以实现超过 5 dB 的宽带衰减，同时在各个指令中实现高达 23 dB 的衰减。这相当于 Zwicker 响度降低了 23%。 (C) 2015 Elsevier Ltd. 保留所有权利。
Active noise control has been applied to a variety of systems in order to improve performance without the increases in size and weight that would otherwise be required by traditional passive noise control treatments. This paper investigates the application of an active noise control system to the control of generator noise in the master cabin of a luxury yacht. A multichannel, multi-tonal active noise control system employing loudspeakers and microphones in the master cabin of the yacht is investigated. It is shown that, due to the high number of engine orders produced by the generator, in order to achieve significantly perceptible levels of noise attenuation it is necessary to control at least 7 individual orders. A controller is investigated which targets 19 engine orders and it is shown to achieve in excess of 5 dB broadband attenuation, whilst achieving up to 23 dB attenuation in individual orders. This corresponds to a 23% reduction in the Zwicker loudness. (C) 2015 Elsevier Ltd. All rights reserved.
