Standard for hotel sound insulation test

Generally speaking, the sound insulation test requirements of hotels are still relatively high. You can hear the sound insulation between walls next door, and the sound insulation volume should be between 45 and 50. The sound insulation requirements for doors and windows are also very high, reaching between 35 decibels and 45 decibels, and the visual effect is good. It is rare to open such doors and windows like a single layer. Generally, only the soundproof window of DEV system can achieve this effect, but in hotels, what we don't have to worry about is the sound between floors, because the sound of floors is mainly some vibrating sound, and carpets are laid inside the hotel, so walking or something will basically not affect the lower floors of the building, so the most important thing is only the walls, doors and windows.
