Soundproof Labs

The SPL Series provides soundproofing for labs or rooms with noise generating equipment (i.e. chillers, pumps, fans, etc.).



Our core strategy is to provide carefully articulated vibration, acoustic, and EMI isolation solutions to the global research community. We are committed to delivering exact solutions for customer research needs, improving the overall performance of our environmental isolation systems, and providing the best customer experience possible for all users. In the end, what is important for us is to have the researcher focus on what matters most: their research (and not their isolation solution). We have been privileged to work with some of the most innovative individuals in the scientific research community and are proud to help advance the research performed by our customers.

SPL Series

Incorporating a uniquely engineered layering methodology to absorb and shield broad frequency noise, Herzan’s SPL Series delivers the quietest operating environment possible for TEMs, SEMs, and other large-scale microscopes.


SPL Series materials are rated to absorb noise based on the material thickness configured, with greater thicknesses offering improved noise absorption over a broad frequency range.

Low-frequency performance upgrades are available (SPL+), utilising Herzan’s proprietary dense material layers, engineered specifically for researchers needing greater noise absorption in the low frequency range (100 – 1,000 Hz).
