Abstract
A kind of lower digging formula sound insulation testing room, including upper sounding room, sound receiving room and sound chamber is issued, wherein the upper sounding room and sound receiving room are set on the ground, testing window is located at Stall plane, the sound chamber that issues is arranged on subsurface, sound receiving room bottom.The utility model is applied to measurement floor, the sound insulation characteristics of the various components such as partition wall, including the sound insulation measurement to air-borne sound and solid sound, the dangerous operation such as can reduce the lifting in test specimen installation process, ascend a height, facilitating test specimen to install, ensure personal safety.
Description
Technical field
The utility model category acoustical testing technical field, more particularly to digging formula sound insulation testing room under one kind.
Background technology
To simulate the sound insulation property of preferable sound insulation measurement acoustic enviroment, test material, component etc..Existing sound insulation testing room
It is mostly three rooms in order to facilitate test, three rooms are respectively positioned on ground level, containing one or so test window and about one
Test window.The test specimen installation of such a setting testing window up and down always needs the lifting higher than 2.0m the dangerous operation such as to ascend a height, right
The personal safety of experimenter has certain danger.
Utility model content
Technical problem to be solved in the utility model is to provide under one kind digging formula sound insulation testing room, by by upper sounding room
And sound receiving room is set on the ground, testing window is located at Stall plane, solve tradition and set the test specimen installation of testing window up and down total
It is to need dangerous operation, the personal safety to experimenter such as ascend a height of the lifting higher than 2.0m to have the problem of certain danger.
In order to solve the above technical problems, the utility model provides a kind of lower digging formula sound insulation testing room, including upper sounding room, by
Sound chamber and sound chamber is issued, wherein the upper sounding room and sound receiving room are set on the ground, testing window is located at Stall plane, it is described
Issue sound chamber and be arranged on subsurface, sound receiving room bottom.
The upper sounding room and sound receiving room, sound receiving room and issue and be respectively equipped with sound proof window between sound chamber.
The utility model is applied to the sound insulation characteristics of the various components such as measurement floor, partition wall, including to air-borne sound and solid
The sound insulation measurement of sound, the dangerous operation such as it can reduce the lifting in test specimen installation process, ascend a height, facilitating test specimen to install, ensureing the person
Safety.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
As shown in figure 1, a kind of lower digging formula sound insulation testing room, including upper sounding room 1, sound receiving room 2 and sound chamber 3 is issued, wherein
The upper sounding room 1 and sound receiving room 2 are arranged on ground 4, testing window is located at Stall plane, and the sound chamber 3 that issues is arranged on
Under ground 4, the bottom of sound receiving room 2.
The upper sounding room 1 and sound receiving room 2, sound receiving room 2 and issue and be respectively equipped with sound proof window 5 between sound chamber 3.
During actual use：In order to avoid the operation that lifts, ascends a height, now the testing window of upper sounding room 1, sound receiving room 2 is placed in ground
Face, issue sound chamber and be arranged on B1, such testing window is located at Stall plane, and the installation process of test specimen avoids too high
Lifting lifting, ensures the personal safety of experimenter.As shown in Figure 1.
