Acoustical Considerations for Engine Test Cells
Description / Abstract:
Purpose
This document discusses, in broad and general terms, the subject of acoustical considerations in engine test cells. One of the primary purposes of an engine test cell is to control the noise emanating from the operating engine in order to reduce noise in the surrounding facility and community to acceptable levels. This is done by the design and installation of specialized acoustic elements and features, which need to be fully integrated into the overall test cell design. It should be further noted, that the requirements of acoustic control are critical to the proper operation of the engine, safety of plant equipment and personnel, and meeting local and legal noise requirements.
Beneficiaries
This document is a compilation of input from several test cell designers, operators and users that summarizes the best practices and recommendations from these experts. This document is intended to benefit operators and owners of engine test cells who are contemplating new facilities, refurbishment of existing facilities, and addition of new engine models to existing facilities. It is intended to aid these owners in understanding the basic terms, regulations, and concerns with engine test cell acoustics. It is not intended that this document be an exhaustive design guide that any owner or contractor could independently accomplish the task of test cell acoustic design and installation. Rather, it is intended to provide a basic knowledge and understanding to operators and owners in the selection and evaluation of acoustic designs and contractors.
Considerations and Consequences of Improper Acoustic Design/Installation
When choosing a contractor for the design and installation of an acoustic solution for an engine test cell, potential risks and loss of productivity should be carefully considered. The consequences of an improperly selected, designed, or installed acoustic system can greatly vary in scope and impact to the customer. Schedule loss can impact and delay the facility ready for operation scheduling. Operational loss can directly create financial and reputation loss due to lost operation and test time for the backlog of engines ready for test. Physical loss can cause loss of life of personnel, engine equipment and surrounding facilities. Financial loss ties in with all of the above where those causes create a financial loss effect.
