Predictable Field Chamber Provides Efficient Acoustic Testing of Automotive Components

CEDAR PARK, Texas, October 12, 2011 – Noise emissions from automotive components are increasingly scrutinized due to the trend for a quieter environment in vehicles. The challenge for manufacturers is how to quantify the noise and accurately measure noise emissions. ETS-Lindgren offers predictable field chambers for engineering or survey grade testing to assist engineers in verifying new designs are compliant with industry standards, such as ISO 3744 (engineering grade), 3746 (survey grade), 7779 (engineering grade) and ANSI S12.54. The chambers provide an acoustically controlled environment for testing while offering high test repeatability.

“We designed these chambers to assist component manufacturers in testing the acoustic performance of their products before they are delivered to the end user,” said Dr. Douglas Winker, ETS-Lindgren’s Acoustics Product Line Manager. “As an example, one of our customers manufactures a motor that raises and lowers windows in cars. As an automotive component manufacturer, they wanted assurance that their product would not adversely impact the full vehicle compliance testing to required industry standards. With the accuracy and repeatability of the measurements offered by our predictable field chamber, they are now confident their product will meet the standard when delivered to their customer,” he added.

In addition to window motors, the predictable field chamber may be used to measure noise levels of seat motors, wind shield wiper motors, rear and side view mirror motors, as well as other internal moving components within vehicles. Standard chambers range in size from 2.13 m (7 ft) x 1.52 m (5 ft) x 2.67 m (8.9 ft) to 5.18 m (17 ft) x 4.57 m (15 ft) x 3.33 m (10 ft 11 in). Custom sizes are available upon request.
