Reducing the noise level

Noise reduction in a garage used as work space

Sound protection measure in the garage of a company:

The garage (built from prefabricated armored concrete panels) was used for dry-ice cleaning processes. To attenuate the resulting high-frequency noise, the company had the garage completely lined with 50-mm thick soni WAVE and soni RESIST sound protection panels. For the reliable fixation of the soni WAVE panels, soniflex special adhesive was used (not suitable for PE foams, e.g. soni RESIST).

The result: The soni WAVE and soni RESIST acoustic panels absorb the high-frequency noise and reduce the noise level in the garage. The additional sound insulation effect of soni RESIST reduced the noise level outside the garage at the same time.

The result was more than satisfactory and the noise reduction effect even better than expected.

Noise reduction in a workshop/work space

After sound-proofing a work station in his workshop with our material, Mr. K. from Reutlingen, Germany, told us:

As we use compressed-air screwdrivers in our workshop, we had a serious problem with high-frequency noise. Since we did not want to wall off the work spaces completely, we decided to build a kind of cubicle lined with sound-absorbing noise protection material around each individual screwdriver.

This measure helped reduce the noise emitted by the compressed-air power screwdrivers to a tolerable level, especially in the high-frequency range. Measurements at about 1 m distance behind the cubicles showed a noise reduction of about 5 to 6 decibels.

The cubicles are made from plywood and 30-mm thick soni WAVE sound protection foam glued to the inner surfaces using soniflex special adhesive. The soni WAVE noise reduction panels are easy to cut with a sharp carpet knife, and applying the soniflex special adhesive is also no rocket science. The sealed surface of the noise reduction panels makes blowing off any dust accumulations easy.

Noise reduction in a basement work space

Mr. F. from Munich told us about a sound protection project in his basement work space:

The basement of our semi-detached house is fitted out as a carpenter’s workshop where I work in my leisure time. The different machines produce a lot of noise that makes working there unpleasant and is also audible in the rooms on the floor above.

When looking for a noise reduction solution I found the soni WAVE acoustic foam on the soniflex website. I lined the ceiling of the basement room with these acoustic panels to absorb the airborne noise produced by my carpenter's machines.

Prior to embarking on the project I asked the soniflex team for advice and they confirmed that thanks to its robustness and excellent absorption values, soni WAVE was perfectly suited for the intended application. Their additional advice: Fixing the acoustic panels on a simple framework of wooden slats instead of gluing them directly to the ceiling would further improve the noise absorption effect, especially in the low frequency range.

I decided to fix the noise reduction panels directly to the ceiling using soniflex special adhesive because this allows for some adjustment before the glue sets.
