"The noise on the road is too loud and I can't sleep quietly, which has caused problems with my sleep," complained a woman. Poor sleep can lead to problems such as lack of concentration and decreased memory during work and study. Prolonged living in a noisy environment can lead to a series of symptoms such as irritability, emotional instability, and decreased patience.

Loud noise, the sound of car horns, the sound of construction, and the sound of planes taking off are all called noises, but the sizes are different. The intensity of sound is expressed in decibels (dB).

30-40 dB: Whispering in the room at midnight (a relatively comfortable and quiet environment)

50-60 dB: Normal human conversation (exceeding 50 dB can affect sleep and rest)

70-80 dB: Piano sound (above 70 dB can interfere with conversations, causing restlessness，

                lack of concentration, affecting work efficiency, and even accidents)

100 dB: Train noise (long-term work or living in noise environments above 90 dB can seriously

             affect hearing and lead to the occurrence of other diseases)

120 dB: Aircraft takeoff sound

Sound is a wave phenomenon, Therefore, the transmission of sound needs medium, which cannot be transmitted in vacuum environment. The vacuum layer of vacuum insulating glass effectively insulates the transmission of sound， especially for the significant effect on medium and low frequency noise generated

 in traffic and daily life, creating a peaceful space.

 Single VIG  weighted sound insulation is  39dB,  and VIG hybrid weighted sound insulation is 42dB.
