Description
Technical Field
The utility model relates to a detection device gives sound insulation is a simple and easy device that is used for detecting the sound insulation performance of flat plate class material goods particularly.
Background art:
with the continuous development of urbanization, various noises affect the life of people. The harm of noise is manifold, not only influences people's health and sleep, but also can reduce staff's efficiency, and then produces various accidents. Prolonged exposure to loud noise can also lead to hearing impairment. The noise level is a quieter environment at 30-40 dB, and the sleeping and the resting are influenced when the noise level exceeds 50 dB; above 70 decibels, normal conversation is disturbed, and the emotion of a person is influenced; the requirements for sound insulation and noise reduction are met as long as the hearing is seriously affected and other diseases such as heart blood vessels are caused in the noise environment of more than 90 dB in long-term work or life. The development of sound insulation materials is one of the main solutions, but detection equipment for the sound insulation effect of material products in laboratories is rare, and a material sound insulation effect evaluation mechanism is lacked, so that a simple and light sound insulation detection device is needed to be designed, and the problems are solved.
Disclosure of Invention
Not enough to prior art, the utility model provides a laboratory is with simple and easy sound insulation testing arrangement possesses simply lightly, portable, need not advantages such as manual control.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a laboratory is with simple and easy sound insulation testing arrangement, includes vocal room, test room, vocal ware, sound detection decibel appearance, vocal room top opening, test room bottom opening, place between vocal room and the test room behind the plate material goods through connecting fixed cover and be connected, vocal indoor bottom surface middle part is through vocal ware fixed bolster installation vocal ware, sound detection decibel appearance is inserted through sound detection decibel appearance socket in test room top surface center.
Furthermore, the sounder fixing support in the sounding chamber and the socket on the top surface of the test chamber are positioned on the same central line, so that the sounder and the decibel detector are positioned on the same central line.
Furthermore, the signal receiving end of the sound detection decibel meter is inserted into the test chamber, and the display screen is kept outside the test chamber.
Further, the distance between the sounder and the signal collecting end of the sound detection decibel meter is 80 cm.
Further, the material used for the sound-emitting chamber and the test chamber was 4cm thick foam.
The utility model has the advantages that:
the utility model discloses a laboratory is with simple and easy syllable-dividing testing arrangement compares with prior art, and its technological progress is showing. The utility model provides a lack the problem of sound insulation test device in the laboratory. The utility model has the advantages of simple structure, the preparation is easy, light portable, need not artifical handheld operation, adaptation material extensively etc, can extensively be used for the sound insulation performance detection of all kinds of flat material goods, respond well.
Drawings
FIG. 1 is a front sectional view of the simple sound insulation testing device for laboratory use of the present invention;
in the figure: 1. an article of sheet material; 2. a sound producing chamber; 3. a test chamber; 4. connecting a fixed sleeve; 5. a sound generator; 6. a sound detection decibel meter; 7. sounder fixed bolster.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings and examples.
As shown in figure 1, a laboratory is with simple and easy syllable-dividing testing arrangement, including plate material goods 1, sound production room 2, test room 3, connect fixed cover 4, vocal ware 5, sound detection decibel appearance 6, vocal ware fixed bolster 7.
2 top openings in sound production room, 3 bottom openings in test chamber, place behind the plate material goods 1 between sound production room 2 and the test chamber 3 and connect through connecting fixed cover 4, 2 interior bottom surface middle parts in sound production room are equipped with vocal ware fixed bolster 7, vocal ware 5 is equipped with on vocal ware fixed bolster 7, 3 top surface centers in test chamber are equipped with a sound detection decibel appearance socket, insert sound detection decibel appearance 6 in the sound detection decibel appearance socket, and 3 top surface sockets in sound production room 2 vocal ware fixed bolster 7 and test chamber are on same center line, make vocal ware 5 and detection decibel appearance 6 be in on same center line. The signal receiving end of the sound detection decibel instrument 6 is inserted into the test chamber 3, the display screen is left outside the test chamber 3, and the distance between the sound generator 5 and the signal collecting end of the sound detection decibel instrument 6 is 80 cm. The material used for the sound-emitting chamber 2 and the test chamber 3 was 4cm thick foam.
During testing, the sounding chamber 2 is placed on the ground with the opening facing upwards according to the figure 1; fixing the sounder 5 on the bracket 7; turning on a sound source and emitting a fixed decibel sound; placing a plate-shaped mortar material product 1 prepared in a laboratory on a sound producing room 2; inserting the sound detection decibel meter 6 into the test chamber 3 from the socket, placing the signal receiving end in the test chamber 3, and keeping the display screen and the keys outside the test chamber 3 without being shielded; placing the testing chamber 3 with an opening facing downwards on the testing material product 1, and fixing the two parts together by using a connecting fixing sleeve 4; and opening the sound detection decibel meter 6 to read after stabilization.
TABLE 1
Table 1 shows test data, and mortar samples 1 to 4 are series of samples obtained by doping the same mortar material with different amounts of a certain component.
