Wait a minute.  You are the one who described this "sirens that approach from the distance, get close, then receded away".  You haven't actually heard the recording?

Yes. I have heard the recording. John McAdams provides it, along with the transcript.

The sirens start softly and build up in volume. And then become went down in volume and could not be heard. The sirens were audible to me for only 36 seconds. And they are clearly loudest near the middle section. And then for the last 45 seconds, the sirens are no longer audible.

This fits with a recording being by a stationary motorcycle, with the motorcade passing by with the sirens blaring. Not with a motorcycle travelling with the motorcade.

Where?

[never mind - just saw your comment in the "HSCA 1978 Acoustic Study by BBN – Figure 367" thread]

Reading through the reelradio comments again, there seems to be some dispute about exactly where Ron Jenkins was and whether he was broadcasting prior to when Pate came on.

The sirens are a problem?! The motorcycle was at the Trade Mart?! Seriously? Yes, I know that's what the pro-WC websites you rely on tell you, but the sirens and the Trade Mart claims were debunked years ago. If the gunfire impulse patterns were not recorded in Dealey Plaza, then, Laurel and Hardy, you two finally, finally, finally need to get around to explaining how echo patterns unique to Dealey Plaza are contained in the dictabelt's gunshot impulse patterns, and how the N-waves, muzzle blasts, and muzzle-blast echoes of those gunshot impulse patterns were recorded in the correct order and interval on the dictabelt.

Again, using BBN’s Exhibit F-367, yes, the blast echo matches for shot 139.27 matches perfectly for a shot:

•   from the TSBD, recorded at microphone 2 ( 6 )
•   from the TSBD, recorded at microphone 2 ( 10 )
•   from the Grassy Knoll, recorded at microphone 3 ( 5 )

Yes, the blast echoes on the Dictabelt match perfectly with a shot fired in Dealey Plaza, regardless whether it was fired from the TSBD or the Grassy Knoll. Come on, the BBN’s own correlations contradict themselves.


No, what you need to explain is why the sirens on the Dictabelt recording only last 36 seconds. Did Officer McLain and the other escorting officers make the 3.4-mile trip to Parkland Hospital in 36 seconds? Or did it take 36 seconds for the for the limousine with the escorting motorcycles 36 seconds pass close by to the Trade Mart Center.

Question 1:

Why are the sirens on the Dictabelt recording only clearly audible for 36 seconds (my estimate)?



The person who continuously dodge simple questions is not the one with the truth on their side.


If you dispute this, others should check out the audio of the Dictabelt and decide for themselves:

I think people notice that you were not too keen to present the audio when asked to do so.
