Noise is a sound that interferes with life emotions or functions, and is a strong sound produced by using machinery, tools, facilities, or other objects generated from factories,
construction sites, roads, and railroads. . These are harmful regardless of the type or quality of snow. Along with urbanization, the main life is exposed to a lot of living noise,
and the comfort of the dwelling is impaired. Therefore, when a house is constructed from the beginning, if the noise level at the construction site is 65 dB or more, it must be
separated from the noise generation boundary by a horizontal distance of 50 m or more, or soundproofing facilities such as sound-proof walls and forest belts must be
installed so that the noise level is less than 65 dB. In addition, living noise such as noise from loudspeakers and noise from factories and workplaces is subject to regulation.
The basis is the regulations on housing construction standards, etc.
