Depends upon the context, of course.
Next to each other in a clean room, of course not, depending upon frequency and listener position, but then that's not what we're talking about, is it.
No, unless the WTC complex was a clean room.
Yes or no. It's very simple.
Could something that produced a sound that measured 140 db. in Central Park, be covered up by something creating 110 db. in Central Park?
Yes
No.
Don't be obtuse.
You're also not specifying whether you're talking about psycho-accoustic interpretation, measured SPL, ...
Measured SPL. Go for it.
All manner of situations could come up where the sources interfere. Shall I go on... ?
Please do. Please explain to me how something that produces 140 db. could be covered up by something producing 110 db, and both sources are within 1500 feet of each other in a direct line of sight, with no buildings or mountains, or anything else in it's way.
Since I have to be VERY specific, I will make sure to list everything for you, since you seem to think that you're being funny and cute.
Way to avoid making a claim. Par for the course I guess.
No you haven't, you've waved away context.
Here's something similarly as pointless...
Can you hear a 140dB *boom* originating at the center of the Earth ?
About as relevant as your question.
Is the WTC in the center of the earth?
Don't be obtuse.
Absolutely. In the same way the broadcast microphones are specifically designed to filter out quite wide frequency ranges, with emphasis on normal human vocal frequency domain, and are generally very directional indeed.
How about ones you would find on camcorders that general civilians not in the news broadcasting field, would have purchased from any electronics retailer like Best Buy or Circuit City, circa 2001?
Context kid, follow along. I'm sorry if the words I am using are too big for you. Let me dumb it down for you.
Do camcorders that general civilians not in the news broadcasting field, would have purchased from any electronics retailer like Best Buy or Circuit City, circa 2001, have the same design as the microphones used to pick up the sounds of a drum set?
On video ? About 8 miles depending upon altitude and atmospherics. You probably mean the sound of hundreds of exposed controlled demolition cutter charges and wotnot. Sure, can be heard pretty easily.
Your point ? You're still arguing without actually running the sim. Yawn.
Sorry, I don't need to run a sim to know that explosives capable of cutting a core column of the WTC would have been extremely loud, and caught on cameras all over Manhattan.
How about one simple cutter charge?
Please pull your head out of your ass and follow along.
How loud was the building descent in dB ?
Obviously loud enough to be caught on film. But wait, didn't you claim that cameras that production people use (Newscrews) filter out those kinds of sounds? But yet, Ashley's microphone caught it.
Imagine that.
(BTW, my limited education in the sound field would guess somewhere around 110-115 db. )
Funny.
