The invention relates to the technical field of noise reduction, and provides an adjustable micro-perforated plate sound absorption system, a control method and a ship. The adjustable micro-perforated plate sound absorption system comprises a sound absorption structure, a stepping motor, a noise measuring instrument and a server, the stepping motor is connected with the sound absorption structure, the stepping motor is provided with a plurality of gears, and the sound absorption frequency of the sound absorption structure can be adjusted when the gears are adjusted; the noise measuring instrument is used for collecting noise generated after the stepping motor passes through the sound absorption structure at different gears; and the server is used for analyzing the noise to obtain a minimum sound absorption evaluation value, and taking a gear corresponding to the minimum sound absorption evaluation value as a target gear of the stepping motor. According to the adjustable micro-perforated plate sound absorption system, when the operation working condition of ship mechanical equipment is changed, the gear of the stepping motor can be directly adjusted to the target gear, so that the sound absorption structure has the optimal sound absorption capacity, and self-adaptive adjustment of the sound absorption frequency of the sound absorption structure is achieved.
本发明涉及降噪技术领域,提供一种可调式微穿孔板吸声系统、控制方法及船舶。上述的可调式微穿孔板吸声系统,包括:吸声结构、步进电机、噪声测量仪和服务器;步进电机与吸声结构连接,步进电机设有多个档位,档位调节时可对吸声结构的吸声频率进行调节;噪声测量仪用于采集步进电机在不同档位时经过吸声结构后的噪声;服务器用于对噪声进行分析,得到最小吸声评价值,并将最小吸声评价值所对应的档位作为步进电机的目标档位。上述的可调式微穿孔板吸声系统,可在船舶机械设备运行工况发生改变时,直接将步进电机的档位调节至目标档位,从而使吸声结构具有最优的吸声能力,实现了吸声结构吸声频率的自适应调节。
