Not every project starts with building an enclosure from the ground up. At Silox India’s facility in Karajgam, Silvassa, the requirement was more targeted: upgrade the acoustic wall lining and door systems within existing noise test booths, without disrupting the layout or the testing equipment already in place. That’s a different engineering exercise than a new-build enclosure. It means working within fixed dimensions, matching the acoustic performance of the surrounding structure, and making sure the new lining and doors integrate cleanly with test benches and access routes that were never designed to be reworked.
Why Wall Lining and Doors Carry So Much Weight in a Test Booth
A noise test booth is only as accurate as its weakest surface. The internal noise floor inside a well-built booth needs to sit at least 10 dB(A) below the product’s specified noise level for a measurement to be considered reliable — and that margin is easy to lose if the wall lining doesn’t manage reverberation properly or if a door isn’t sealing the way it did when the booth was first commissioned. Over time, lining material can degrade, panel joints can loosen, and door gaskets wear down, all of which quietly erode a booth’s test accuracy long before anyone notices from the outside.
For Silox India, getting this right meant the difference between test data that manufacturing and R&D teams could trust, and readings skewed by reflections or sound leakage that had crept in over time.
What Ecotone Systems Delivered in Noise Test Booths
Ecotone Systems approached this as a targeted acoustic treatment rather than a generic panel swap:
- Acoustic wall lining designed to minimise reverberation and sound reflections inside the booth, keeping the internal environment neutral enough for accurate, repeatable readings.
- Door systems engineered for consistent sealing, addressing the point where most booths lose performance first, so noise leakage at the access point wouldn’t compromise the improved wall treatment.
- Integration with the existing booth structure, matching the upgrade to Silox India’s current layout and test setup rather than requiring a rebuild.
- In-house acoustic and structural expertise, applied to make sure the lining and door work functioned as one coherent acoustic system, not two separate fixes.
The Result
The upgraded wall lining and doors were completed without interrupting Silox India’s ongoing testing schedule, restoring the booth’s acoustic performance to the level needed for dependable measurement work. It’s a reminder that acoustic performance isn’t a one-time install — booths in continuous use need their lining and door seals checked and refreshed over time, the same way any precision equipment needs recalibration.
Why This Matters Beyond This Project
Many facilities assume an underperforming test booth needs to be replaced entirely. This project shows that isn’t always true. When the core structure is sound, a focused upgrade to wall lining and door sealing can restore accurate acoustic performance at a fraction of the cost and disruption of a full rebuild — provided the work is done by a team that understands how lining, sealing, and structure interact as a system, not as separate line items.
