Because the production of chopsticks uses machines, it will inevitably produce noise: cutting raw bamboo (sawing machine), cutting bamboo strips (cutting machine), knotting and dicing with fixed width (slicer), bamboo wire forming (wire drawing machine), cutting to length (cutting machine) and grinding chopsticks; Carving (automatic sharpening machine) and packaging (automatic packaging machine); Firstly, the prepared blank is sliced (slicer), molded with wood thread (wire drawing machine), cut to size (cutting machine), sharpened and carved with chopsticks (automatic knife sharpener), and packaged out of the factory (automatic packaging machine).
The standard usage of noise is noise. From the physiological point of view, any sound that interferes with people's rest, study and work and the sound that people want to hear, that is, unnecessary sound, are collectively called noise. When noise has a bad influence on people and the surrounding environment, noise pollution is formed.
In physics, noise refers to all irregular signals (not necessarily sound), such as electromagnetic noise, thermal noise, noise during radio transmission, laser noise, optical fiber communication noise, picture noise when a camera takes pictures, etc.
