Acoustical engineering services assist customers with materials selection, noise budgeting, and design strategies. ATL customers benefit from specialized educational resources, including design and equipment selection guides, technical workshops, and multimedia instructional products.

A three-day short course, "Low-Noise Design of Space Flight Hardware," is presented annually at GRC by Nelson Acoustics for payload developers and other International Space Station stakeholders. In 2005, a new course, "Fan Noise," was offered, presented by Nelson Acoustics with co-instructor Cathy Biber of Biber Thermal Design. These courses involve lecture-style classroom sessions, lab tours, demonstrations, and case study discussions that feature guest lecturers and visiting experts as well as NASA participants.

The ATL has produced a Field Test Procedure that provides guidance for acquiring the most accurate acoustical measurements in situ when it is impractical to move hardware to the Acoustical Testing Laboratory chamber. This procedure, developed by Nelson Acoustics, may be used by payload developers who are unable to arrange for testing in an anechoic or hemianechoic chamber.

ATL's compact disc of Auditory Demonstrations, "Auditory Demonstrations II: Challenges to Speech Communication and Music Listening," was developed as a low-noise advocacy tool for stakeholders in the International Space Station Program.
