Eckel Noise Control Technologies has been an industry leader in building acoustic research and testing facilities since 1952. Utilizing patented technology Eckel’s full and hemi-anechoic chambers, portable anechoic chambers (PACs) and SuperSoft test chambers incorporate the most advanced acoustic design elements to create optimal sound environments suitable for virtually any type of acoustic testing or research.  

Testing facilities designed for acoustic analysis are echo-free enclosures that provide a free-field environment, allowing sound waves to propagate in all directions without obstruction or reflection. Eckel’s unique, patented wedge design provides an optimum level of sound absorption, allowing precise, repeatable acoustic measurements.

Oliver Eckel, the company’s founder, helped lay the groundwork for anechoic testing by assisting in the development of Harvard University’s Cruft Laboratory chamber in 1945. Commissioned by the National Research Defense Committee as part of a top secret research project it was the first anechoic chamber ever to be built. Since then Eckel Noise Control Technologies has continued to be a pioneer in the field of acoustic research having built facilities worldwide for a wide array of customers within the automotive, telecommunications, consumer product, aircraft/aerospace, audio, and academic communities.
