The House Select Committee on Assassinations (HSCA) would study acoustical evidence that the Warren Commission (WC) used in 1964. It was a recording of the assassination made on the Dallas Police Department (DPD) Dictabelt by a motorcycle police officer leaving his microphone open.
These recordings would be studied by a firm called Bolt Beranek and Newman, Inc. (BBN), and Dr. James Barger, who was the firm's chief scientist, would analyze them in 1978. After Dr. Barger's presentation the HSCA called a further witnesses to discuss this issue.

Professor Mark Weiss would study the work of Dr. Barger's in regard to the possible shot from the Grassy Knoll (GK).

Mr. CORNWELL - And you began that work in early October?
Mr. WEISS - That is correct.
Mr. CORNWELL - And you just very recently concluded the work; is that correct?
Mr. WEISS - Yes, sir.
Mr. CORNWELL - Based upon the work, were you able to reach a conclusion with any greater degree of certainty as to whether or not that shot did or did not occur?
Mr. WEISS - Yes, sir, we did.
Mr. CORNWELL - And what was your conclusion?
Mr. WEISS - It is our conclusion that as a result of very careful analysis, it appears that with a probability of 95 percent or better, there was indeed a shot fired from the grassy knoll. (HSCA V, p. 556)

This proves that a conspiracy took place as even if Lee Harvey Oswald (LHO) was the assassin, and the evidence shows that he wasn't, and he acted alone, he couldn't have fired from two places at once.
Was the technology so bad in 1964 that the WC couldn't have figured this out too? With the full resources of the FBI behind them I doubt this was true. The only other option is they ignored this evidence and based on their history of ignoring evidence that didn't point to LHO this is the most obvious option to me.
They determined this by making a noise like a rifle shot from a particular place and then measure the echo pattern so they can differentiate locations by different echo patterns. In other words, the echo pattern for the Grassy Knoll (GK) position would be different from the echo pattern of a sound from the sixth floor window of the Texas School Book Depository (TSBD).
Weiss told the HSCA that this is a basic principle in acoustics and has been known for “several hundred years”. (Ibid., 558) He affirmed that these were “fundamental things in acoustics”, and that they needed only to apply these “basic well-tested, well-established principles and nothing more" according to Weiss. (Ibid.) Weiss explains this further.

Mr. CORNWELL - Then from that process, as I understand, you were able to sort of confirm what the real echo structure of Dealey Plaza was?
Mr. WEISS - Yes, sir.
Mr. CORNWELL - Which surfaces in it generated echoes from roughly the area of the grassy knoll and being received roughly in the area of the second pin?
Mr. WEISS - That is correct. These surfaces would be correct for that set of conditions for something out here and for something in around here. For something elsewhere it would have been perhaps a different set of echo-generating surfaces. (HSCA V, p. 566)

They were able to determine where a noise originated based on the echo-generating surfaces in that area. Weiss will state that the noise was not a motorcycle backfire, but a gunshot.

Mr. FAUNTROY - …Mr. Weiss, you have cleared up for us the question as to whether you employed the marvels and refinements of computerized electronics to reach your conclusion about the 95 percent chance shot from the grassy knoll. You have also dealt with noises are indistinguishable to the unaided ear. And is it your testimony which that the shots that you have distinguished were not back fires?
Mr. WEISS - Not exactly so, sir. In the case of shot No. 3, since there is evidence of a shockwave preceding the muzzle blast, then it would have to be concluded that this was not a backfire, since backfires are not known to produce shockwave sounds.
Mr. FAUNTROY - Then your answer is yes, that the shot which you examined, the noise that you examined, was not in fact a backfire?
Mr. WEISS – That is correct, sir. (HSCA V, p. 588)
historymatters.com/archive/jfk/hsca/reportvols/vol5/html/HSCA_Vol5_0296b.htm
This makes it clear that the noise was NOT a motorcycle backfire. Weiss said earlier if it was then it had to be behind the stockade fence on the GK and this isn't very likely.
This was the basis for the HSCA’s conclusion that there probably was a conspiracy in the assassination of President John F. Kennedy (JFK). Of course the WC endorsers deny this and claim that this acoustical research has been “debunked", but of course this is false. There is much more evidence showing that there was a conspiracy in the assassination of JFK than just this acoustical evidence, and it is covered both in this series and the “Statements That Sink The WC's Conclusions” series. It overwhelmingly shows that at least one shot came from the GK area, and that a conspiracy was involved in the murder of JFK.
