What kind of measurements are "measurement certification businesses" conducting? Here are a few representative examples briefly introduced!
The modern world is overflowing with various sounds. It is generally said that a sound level below 45 decibels is considered "quiet," and there are various regulations regarding different types of "sounds" depending on the country and municipality. The standards for permissible sound levels are precisely defined based on different conditions, such as residential areas versus commercial areas, and daytime versus nighttime. Measuring these sound levels is possible for anyone with the appropriate equipment, but businesses that have received specific authorization from prefectures can submit the measurement results as an official report. This report is a public document that is also valid as court evidence. Authorized businesses are referred to as "measurement certification businesses." *You can view the detailed content of the blog through the related links. *For more information, please refer to the PDF materials or feel free to contact us.
