Creating a fully sound-isolated product testing lab inside your factory is essential if you need to run accurate noise level tests, vibration performance tests, or audio quality testing on your finished products. The EPS Cement Sandwich Panel is one of the most affordable materials that can deliver the high level of sound isolation you need for these kinds of precision testing environments. The high STC 42+ sound insulation rating of the panels blocks almost all external industrial noise from your production floor from entering the testing lab, so the background noise level inside the lab can stay low enough to run even very sensitive audio and noise measurement tests. The rigid dense panel structure also prevents external structural vibration from your heavy machinery from traveling through the wall into the testing zone, which would otherwise ruin the accuracy of your precision vibration test results. You can build a fully enclosed double layer panel wall system, with an air gap between two layers of EPS Cement Sandwich Panel, to achieve an even higher level of sound isolation, creating a lab environment that is quiet enough for even the most demanding acoustic testing work. Unlike professional acoustic lab construction that costs a fortune, you can build this high performance testing lab for a fraction of the price, using standard industrial grade panels. This lets even small and mid-sized manufacturing businesses set up their own in-house product testing facilities, instead of paying expensive third-party testing labs to run their product performance tests for them, saving huge amounts of time and money on every new product development project.
