Conversion noise

Noise is the vibration of a frequency that is cluttered. With the increase of transportation and population density, the increase of family facilities and the increasing noise, it has become a major public pollution of the human social environment. There are many disadvantages to noise:

Noise exceeding 85 decibels can upset people, interfere with sleep, and affect work efficiency. Strong noise can also damage the hearing, causing tinnitus, earache, and hearing damage. Noise above 115 decibels can also cause deafness. Noise also damages vision. When the noise intensity reaches 90 decibels, the sensitivity of human visual cells will decrease.

Finally, in 2030 I became an expert in sound. After that, I specialized in the topic of noise. After two years, I invented a "noise converter." This converter has three functions of absorption, conversion and output, which can absorb tens of thousands of square meters of noise in an instant. After the filter is converted, it becomes a beautiful music.

The noise conversion was successful, the noise has disappeared, and people live a happy life.
