Acoustical Measurements

Multi-channel acoustical measurements can be acquired to provide clients with real-time 1/3rd octave band, A-weighted, and FFT measurements. Measurements on impulsive sound sources are also available.

Data output formats allow easy comparison of test article acoustic emissions against published requirements. The ATL has developed data reporting templates for most flight hardware installed configurations.

PDF Sample data output for Microgravity Science Glovebox (MSG) experiment (.pdf file)
PDF Sample data output for Express Rack experiment (.pdf file)
PDF Sample data output ISS Rack-level test article (.pdf file)
Adobe Reader You will need to install the free Adobe Acrobat Reader viewer software to see the documents that are in Portable Document Format (PDF file).
