The interlayer noise dampener residual deformation tester is test equipment that tests the load of the noise cushioning material used in building construction.

The load control test is carried out in 4 stages.

1) 22.5 N (250 Pa) Hold for 120 seconds

2) 180 N (2,000 Pa) hold for 120 seconds

3) 4,500 N (50,000 Pa) hold for 120 seconds

4) 180N (2,000 Pa) Hold for 300 seconds

Measure the average compressive strain at the end of the load retention test time for each step.

4 compression displacement sensors installed.?

It is possible to calculate the average strain value by means of the 4 compression 

displacement sensor and the software programing.
