NASA horn tower

Believed to have been the very first NASA structure installed at what is now Stennis Space Center, this 30 foot tall, 12 by 12 foot wide acoustical horn was brought to the facility from the Marshall Space Flight Center in 1962, where it had been in use for two years. It was installed at a former residence two miles northeast of Gainesville.

 

The horn was used to study sound propagation in the vicinity of the center, and marked the beginning of what was to become a sophisticated atmospheric sounding station. Acoustic readings were taken during the horn’s operational life using trucks with microphones, and between 1962 and 1965 there were 2,575 observations taken using the horn.

 

This work was undertaken in order to ensure that the sound levels which were expected to be generated by static firing of rocket engines would not be harmful or inconvenient to surrounding residents, and it was based on the findings that the buffer zone has been maintained at its original size
