It appears the group in my corporate home responsible for exterior maintenance (familiarly know as the “leaks & squeaks department”) has approved the method shown below for identifying bad slab areas to be cut out & patched…
“Hey Bob, does it sound a little different here to you?….(I think there’s still lots of money left in the budget….and I’ve got a boat payment coming up)”
It’s hysterical…..(extra points if you can identify the bridge in the background…the name is historical…..)
From building boxes and fitting face frames to installing doors and drawers, these techniques could be used for lots of cabinet projects.

What happen to the Louisville Slugger?
Roman Polaski Bridge? (Wild guess ....)
More like a WAG......but if movies are your thing, think Linda Blair.....
I have seen many companies check bridge decks by the chain method. Why go high-tech when low tech works fine?
but what are they checking for?. 2+3=7
Heck if I know what they are checking for. Just seen it happen a lot of times on briges.
So I guess hearing protection isn't recommended
just asking because, I cannot do any testing thats not astm or aashto approved. My boss would fired me over something like that.. 2+3=7
oh, maybe because the method's completely subjective, depends on who is listening, has no documentation, is rife for abuse, and, all the holes they've cut here (the building looks like a concrete termite has been working on it) have had 1) no visible evidence of spalling before they cut them, and 2) no visible evidence of rusted re-bar as they cut them....I like to KISS as much as anyone else, but IMHO the work they are doing here will come back to haunt them in the form of innumerable patches failing well before the original deck would have.
I don't suppose that the guy standing on the ledge in rubber boots would attenuate the sound at all ...

The chain is definitely low tech.
What caught my eye was the tool in the background. Looks like a heavy grinder without any guard ? If I'm seeing it correctly, anyone using same is a fool. (Those disks shatter, can easily maim or kill.)

Well, they have to leave the guard off so they can use it instead of a wire brush to clean off the rebar, after they expose it & let it rust in the rain & snow for a week or so.....
Looks like the Key Bridge between Washington, DC and Rosslyn, VA.
Ladies and gentlemaen, we have a winner....Hard by the banks of the great grey green greasy Powtowmak river.....the area's gotton much busier, the politicians worse, but the river just keeps rollin'.....
Hello there Uncle Dunc -
Your name has come up a bunch of times. You've been missed. Nice to hear from you again, stick around.

Looks like the Key Bridge Marriott.
It does look silly, but acoustic testing is actually quite effective and refined. Remember when you were a kid how you checked for a cracked baseball bat by the sound? When I was in college a professor was working on using ultrasound to detect broken bones in a similar way.
Acousting testing is also used for leak detection (automakers check weatherstripping, and pipefillter find vacuum leaks), and for measuring the thickness of pipes and tanks without access to both sides of the material.
Shhhh....don't tell anyone, OK
Accoustic testing, in and of itself, is good....but usually involves standards of some kind....
I'll post a picture of the swiss cheese balconies tomorrow.....
Yes, it is the Key Bridge, one of several bridges that connect northern VA with Washington DC. It is acutally the Francice Scott Key Bridge named for the author of the US national anthem The Star Spangled Banner.
