NASA GRC Guide to Specifying Equipment Noise Emission Levels

• realistic and achievable baseline noise criteria
• guidelines for optimization of noise emission criteria based on applicable operation and siting conditions
• template specification language
• vendor submittal forms
• an optional post-installation test procedure

Please note that this program is focused solely on hearing loss prevention and does not address other important noise exposure issues such as speech intelligibility and work environment comfort that are often associated with moderate- or lower-level noise sources. A comprehensive approach to noise exposure management will consider these lower and moderate level noise issues as well as hearing loss prevention when developing requirements for any siting, procurement, and design projects.
