We are deeply harmed by noise because of poor sound insulation in work and life, so how much sound insulation is good?

Depending on the use conditions, different sound insulation equipment, sound insulation rooms, and environmental conditions, the requirements for sound insulation are different. The basis for judging the sound insulation needs to be measured in combination with the actual internal and external noise of the environment. The following is an example of environmental protection.

Sound insulation for family residences and shopping malls

Many friends in life are deeply troubled by residential noise, the noise of naughty children, the music of the KTV bar downstairs, the sound of vehicles on the road, the speech of grandpa and aunt in the early morning, the soul sound insulation of square dance in the middle of the night, etc. For this kind of sound, the sound insulation of about 30 decibels can be effectively blocked. Because people are suitable for sleeping in an environment of 30-40 decibels, the normal living environment is about 40-50 decibels, and the outdoor noisy environment is generally about 60-80 decibels, so the sound insulation of 30 decibels can basically isolate the troubles caused by noise. The noise sources of shopping malls and business districts are similar to those of families, but due to the dense population, the noise sources are relatively concentrated, and the sound insulation of about 30-40 decibels is required.

Sound insulation of industrial workshops

Due to the operation of machines in industrial production, the noise is generally large, and the highest can reach more than 130 decibels. Most factory environments are around 70-100 decibels, and the national standard for noise workshops must not exceed 80 decibels, so the sound insulation of general industrial areas can also meet about 30-40 decibels. If there are special requirements, the sound insulation needs to be around 50-60 decibels to be considered a relatively good sound insulation.

Sound insulation of soundproof equipment

The higher the sound insulation of soundproof rooms, anechoic rooms, silent rooms, silent boxes, soundproof covers, audiometry rooms, soundproof doors, soundproof windows, soundproof boards, sound barriers, etc., the better. In actual use, the sound insulation requirements will be designed according to specific needs, because the higher the sound insulation, the higher the price, so it is enough to meet the requirements. The ideal sound insulation of these equipment is generally between 30-50 decibels, mainly depending on the needs of the user.

In general, no matter what the environment is, the sound insulation must be above 30 decibels to be considered good. In terms of sound insulation effect alone, the higher the better. It is recommended that you choose according to actual requirements.
