Ring around Orion: Lockheed Martin acoustic testing

Re: Ring around Orion: Lockheed Martin acoustic testing

All they could get was 143dB with that number of speakers that took up 3 trailers at that distance?

Seems like they made a bad choice of cabinets--------------

Perhaps 143dB was the target number that Lockheed Martin was looking for, and perhaps the large number of speakers used there was for rapid locational/positional switching around the circle of arrayed speakers, and not solely for generating massive dB levels; the next to last paragraph in the article alludes to the reason that Lockheed Martin used this particular configuration.

The speakers and expertise for this testing are sourced from a local sound provider here in Maryland. As you can no doubt tell, a lot of it is just off the shelf Vertec stuff. However, the low end cabinets are all proprietary and built specifically to meet the testing specifications.

The real trick in these tests in not just in making it loud. it's making it loud at precisely the right locations and at precisely the correct frequencies and then being able to measure that. That's a whole lot more tricky than just getting a box to get very loud, not that that isn't a trick in and of itself.

Does Danley possess the expertise to provide the tools to do this job? Given the time to develop it i'm sure they do. But having seen this stuff up close i can tell you the sophistication of what is going on here is no less admirable.

For those of you who like to know more about things...

What is D-FAT?

That is not really a question.

Who did the Military turn to when then wanted a "super sub"? Built to specific specs?

Who did they turn to when they wanted a lightweight extremely highout sub that did not need to go real low?

The BC412 was the result of that.

Although both projects ended up dying (due to politics), some amazing products came out of it.

When it comes to focusing high output sound, I don't think there is a question about what Danley can do.

Ivan, i don't understand your response. Unless you misunderstood what i was saying.

I wasn't questioning the technical expertise of you or anyone at the Danley company. I was acknowledging it. While simultaneously acknowledging the expertise of the folks who designed, built and implemented the DFAT system. My apologies if it didn't come across that way.
