Full and Hemi-Anechoic Chambers
Eckel’s Full and Hemi-Anechoic Chambers are custom-engineered structures designed to create the ideal acoustic environment in which to conduct testing and research within an array of industries and disciplines. These state-of-the-art echo-free enclosures have a sound energy absorption level of 99+% and are precision-designed and custom-fabricated to the meet the frequency specifications required to achieve exacting scientific and product testing goals.
Eckel helped lay the groundwork for anechoic testing by assisting in the development of the first chamber ever constructed and in the more than 65 years since then 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, high-tech and academic communitiesChamber Construction
Eckel’s Full and Hemi-Anechoic Chambers are custom-engineered structures designed to create the ideal acoustic environment in which to conduct testing and research within an array of industries and disciplines.
The type of product being analyzed and the nature of the data to be collected determine chamber size, outer structure and most importantly the geometry and design of the proprietary acoustic treatment used to achieve the set performance goals. Using that information each chamber is precision-engineered and custom-fabricated to the meet the frequency specifications required to achieve the testing criteria set forth by the customer. Attenuating Structures
In order to obtain a suitable acoustic environment, the anechoic wedges should be installed in a proper noise and vibration isolating structure. This enclosure may be one of several types of construction built on an isolated floor, or floated on springs or other vibration isolation material.
A masonry enclosure is typically used in new construction, or when the anechoic chamber is planned as an integral part of a new building. An envelope of 8″ or 12″ masonry block usually provides adequate ambient noise and vibration reduction. The addition of an inner panel room provides increased noise reduction if required. Walls should be constructed on an isolated reinforced floor separated from the building floor or in a pit to allow the working floor in a chamber to be flush with the host room floor.Full Anechoic Chambers
