Problems solved by technology

[0003] Although the noise of modern textile machinery has been greatly improved compared with the previous equipment, the noise problem has not reached the level that does not affect the comfort of the human body. The existence of noise seriously affects the communication and communication of textile workers in the textile factory. own physical and mental health

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0017] refer to figure 1 , in this embodiment, the textile noise reduction device includes a sound-proof cover covering the human ear, and the sound-proof cover includes:

[0018] Sound collector 20: for collecting all the sounds in the environment, and sampling and encoding the sounds.

[0019] Processing control module 10: used for noise separation of the sampled and encoded sound by frequency.

[0020] Sound output device 30: output the sound after noise separation to the human ear.

[0021] The processing control module 10 can adopt an embedded system, and a human voice recognition and separation program is installed in the embedded system. The algorithms of the human voice recognition and separation program have good separation effects in the published materials.

[0022] In the aforementioned textile noise reduction device, the processing control module 3...

Abstract

The invention provides a spinning noise-reduction device which comprises a soundproof cover covering ears of a person. A sound collector, a processing control module and a sound output device are arranged in the soundproof cover, wherein the sound collector is used for collecting of all sound in an environment where the person is located and sampling and coding the sound, the processing control module is used for performing noise separation on the sampled and coded sound according to frequency, and the sound output device is used for outputting the sound with noise separated to the ears of the person. The soundproof cover is adopted to directly isolate noise in a spinning mill, and the noise is effectively prevented from damaging the health of spinning workers.

Description

technical field [0001] The invention relates to the field of textile noise reduction equipment, in particular to a noise reduction device for closed earphones. Background technique [0002] The public hazards produced by textile machinery mainly include noise, dust, toxic and harmful gases and waste water containing harmful substances. There are two reasons for this: equipment factors and process factors. Noise is a kind of mechanical vibration wave with air as the carrier. In most workshops of textile mills, especially in weaving workshops, there is a lot of mechanical noise. Measures that can be taken in textile machinery include: lining the inner wall of the shell with sound-absorbing materials, replacing the chain drive and gear drive with a flexible toothed drive belt, improving the accuracy and dynamic balance of moving parts, and connecting high-speed parts and racks. Install damping washers, etc. However, some noise reduction measures also bring negative factors,...
