TasDom Posted March 8, 2016 Share Posted March 8, 2016 That's very interesting...... "Seventy to 100 microphones placed on and around the Orion capsule provide feedback, so the engineers know whether the sound waves are diffusing properly". 2016: A Space Audyssey 1 Quote Link to comment Share on other sites More sharing options...

garyrc Posted March 8, 2016 Share Posted March 8, 2016 2016: A Space Audyssey Lol. I assume they are using a test signal that has the same spectral characteristics as the launch blast, namely with a lot of bass. I hope that immediately after each test they play Thus Spake Zarathustra. That 4 octave bass C chord could grow right out of the test sound.

Moderators dtel Posted March 9, 2016 Moderators Share Posted March 9, 2016 Very cool, wish they gave a little more detail about amps and power required. Quote Link to comment Share on other sites More sharing options...
Tweaker256 Posted April 26, 2016 Share Posted April 26, 2016 I believe the setup was from Maryland Sound International, it's called DFAT, Direct Field Acoutic Test and is used as an alternative to a full up acoustic test chamber. It can be setup anywhere, it takes amps that come in a tractor trailer rig! We're talking 140+db over the entire surface of a spacecraft. http://www.msi-dfat.com/ Quote Link to comment Share on other sites More sharing options...
