[top] History

Completed in 1974, this laboratory was NASA's major research facility for studies to understand, predict and reduce aircraft noise. Separate areas within the facility house investigations in acoustic properties of materials used in aircraft, and study the effect of both isolation and reverberation of noise. Still other areas simulate aircraft noises outside and inside buildings for evaluation by human subjects. Developments made in this facility find their way into future aircraft and air terminals.

The first two pictures below, and the first two documents, pre-date the Noise Reduction Facility. These photos are a reminder to readers that Langley was in the Noise Reduction business many years before Building 1208 was constructed. Muffler development testing was part of a center-wide flight investigation including muffler development testing in the Full-Scale Tunnel. The effort Is discussed in detail at the Full Scale Tunnel Site as well as in the first two documents for 1208.
