Description

Technical Field

[0001] This utility model relates to the field of noise cancellation technology, and in particular to a noise isolation room. Background Technology

[0002] Existing noise isolation rooms can reduce the noise inside by 8-15 decibels before transmitting it outside. However, these rooms cannot meet the noise reduction requirements for some large equipment. Furthermore, current noise isolation rooms lack noise testing equipment, making it impossible to accurately measure the noise levels inside and outside the rooms.

[0003] Designing a noise isolation room that effectively reduces noise and accurately tests the noise levels inside and outside the room is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem solved by this utility model is to provide a noise isolation room with good noise reduction effect and capable of accurately testing the noise situation inside and outside the noise isolation room.

[0005] To achieve the above and other related objectives, this utility model provides a noise isolation room, comprising: a main body of the room including a top wall and side walls, the top surface of the side walls being connected to the top wall, and the bottom surface of the side walls being disposed on the ground; the side walls including a front side wall, a right side wall, a rear side wall, and a left side wall connected in sequence; The inner surface of the side wall and the inner surface of the top wall are both provided with a sound insulation structure. The sound insulation structure includes, from the outside to the inside, a damping sound insulation layer, a double layer of sound insulation cotton, a keel layer, a sound insulation felt layer, a flame retardant board layer and a gypsum board layer. The front wall is equipped with a soundproof door and a soundproof window; the soundproof window includes an inner glass and an outer glass arranged sequentially from the inside to the outside, and both the inner glass and the outer glass are double-layered laminated soundproof transparent glass. An external noise collector and a noise display device are provided on the outer side of the front wall, and an internal noise collector is provided inside the main body of the room. Both the external noise collector and the internal noise collector are connected to the noise display device.

[0006] Preferably, the double-layer sound insulation cotton is provided with multiple wall vibration dampers.

[0007] Preferably, the inner surface of the top wall is connected to the sound insulation structure via multiple shock-absorbing hooks.

[0008] Preferably, the thickness of the damping sound insulation layer is greater than or equal to 2 mm.

[0009] Preferably, the thickness of the sound insulation felt layer is greater than or equal to 3 mm.

[0010] Preferably, the thickness of the flame-retardant board layer is greater than or equal to 18 mm.

[0011] As described above, the noise isolation room of this utility model has the following beneficial effects: In this noise isolation room, the damping sound insulation layer effectively reduces noise propagation by consuming sound wave energy and suppressing vibration; the sound insulation felt layer reduces noise propagation by reducing sound propagation and vibration transmission, thus achieving dual vibration reduction and noise reduction functions; the double-layer sound insulation cotton effectively isolates noise; due to the large weight of the double-layer sound insulation cotton, connecting it to the keel layer allows the keel layer to stably support the double-layer sound insulation cotton; the gypsum board layer and the flame-retardant board layer give the noise isolation room a fireproof effect, and the gypsum board layer also effectively insulates sound. The soundproof door facilitates personnel entry and exit while isolating noise, and the soundproof window allows personnel to observe the interior of the noise isolation room while isolating noise. An external noise collector can collect noise from outside the noise isolation room, and an internal noise collector can collect noise from inside the noise isolation room. The noise collected by both the external and internal noise collectors can be displayed on a noise display device. Using this noise isolation room, the noise inside the noise isolation room can be reduced by 30 decibels. This noise isolation room has a good noise reduction effect and can accurately test the noise levels inside and outside the noise isolation room. Attached Figure Description

The noise reduction effect of this noise isolation room is good, and the noise situation inside and outside the noise isolation room can be accurately tested.

[0019] The double-layer sound insulation cotton 220 is equipped with multiple wall vibration dampers 221, which can effectively reduce wall vibration and noise.

[0020] The inner surface of the top wall 110 is connected to the sound insulation structure through multiple shock-absorbing hooks 600. The installation of the shock-absorbing hooks 600 can reduce the vibration noise propagating upward.
