Abstract

The invention relates to a textile machinery reverse noise noise reduction method. The textile machinery reverse noise noise reduction method comprises the steps that a sound intensity probe is used to acquire noise signals during a working process of textile machinery; the noise signals are analyzed and processed, and the spectrum maps of the noises are acquired; reverse noise spectrum maps required by the noise reduction are acquired according to the spectrum maps of the noises, analogue simulation is carried out to acquire slicing results; an amount and positions of loudspeakers are determined according to the slicing results, and reverse noise signals are transmitted by the loudspeakers to cancel the noises. The noise cancellation is completed by applying the reverse noises opposite to the spectrums of the noises, and therefore the working requirement of reducing the noises during the working process of the textile machinery is satisfied.

Description

technical field [0001] The invention relates to the technical field of mechanical noise reduction, in particular to an inverse sound noise reduction method for textile machinery. Background technique [0002] Textile machinery is all kinds of mechanical equipment needed to process natural fibers or chemical fibers into textiles. It is precisely because of the rapid development of textile machinery that people's ever-increasing living requirements can be met. Existing textile machinery is no longer just for clothing, but appears in people's lives and at the forefront of technological development in various forms such as carpets, shoe uppers, airplane wings, and space suits. In order to meet social needs and improve product quality, textile machinery usually processes at a relatively fast speed, so it is inevitable to cause noise and damage the body of the machine operator. [0003] Through continuous investigation and research, it is found that working in a noisy environmen...
