The fact that you can get a usable recording indicates that most things are basically working. Does your headset incorporate an amplifier? When you listen to the recordings, are you using the same computer and headset?

Yep, everything has been done on the same dell laptop, including listening to recordings. I can't imagine the headphones would have a built in amp... they're just some cheap earbuds that I carry for music listening.

Question

Hey! How are you guys using your lap tops as a listening device to listen to Det in real time.
I have an old pc mike with a long Coax wire that should be great for this.

Thanks

Well, I just plug the mic into the mic port and turn up my volume (make sure the mic input is enabled in "Volume Control") . Using a headset is highly recommended.

Cool thanks. I'll try again.

This thread coming back got me to thinking about if anyone has used a non electronic version of det cans? Copper lug or a piece of copper tubing then to a hose like air compressor hose into the car. The gray foam water pipe insulation for additional sound deadening from outside sources. To a stethoscope (like a doctor uses). I just wondered if anybody has tried both. I made an electronic version and this version and felt that I could hear the beginnings of knock better with the manual version. It was more difficult to install but the sound transferred into the stethoscope really well.

I built one of these but seem to be picking up a lot of external noise with it -- intake, BOV, etc. If you have a recording of how it's SUPPOSED to sound, can you attach it?

Dude, it's a mic. It's designed to pick up sound.

The lug version will be better at picking up engine block sounds vs. external sounds than the clip version.

It's picking up so much I doubt I could hear detonation over the racket. I'm building the clip version today.

Bump because I'm going to build one too, but have a question.

The link you provide shows the tip and ring get connected together to one of the microphone wires, and the second microphone wire gets connected to the shield and ground. So which is it?

Maybe this will become more obvious when I find the microphone; the tiny RadioShack in the mall didn't have jackshit.

You'll have to look at the packaging for the microphone. On the ones I can find around here, the microphone had the 3 wires (red, white and bare) and the packaging described what each wire's function was.

RadioShack is a shell of what it used to be. They are just another wannabe cell phone retailer these days and may not last much longer. There's always Mouser.

Just a bump and some questions because I just bought a set of those noise canceling headphones (for range use) that also have an audio in jack.

Amazon.com: 3M Peltor Tactical 6-S Slim Line Electronic Headset with Audio Input Jack, Olive Green: Home Improvement Amazon.com: 3M Peltor Tactical 6-S Slim Line Electronic Headset with Audio Input Jack, Olive Green: Home Improvement

Basically I got the above in black, for $49 at Home Depot. Such a deal.

I am wanting to use these as my headset for listening when not plugged into a laptop. I saw "personal listener" described above but it seems like the versions I am finding on ebay tend to be the ones that are designed as a serious assistive device and are quite pricey.

Anyone have any search terms or sample listings I can check out? Is creating a DIY mic power box something that would be easy to do?

Those looks like those might have a built in amp already, maybe they dont need an external amp to work.

Searching for "headphone amplifier kit" on Amazon has turned up some results.
This one This one
is prebuilt, about $36 bucks, and looks reasonably durable.

Personal Sound Amplifier

I use this, extended the microphone to the engine and left the "amp" in the center console. I just use earbuds, but you could use those with a M/M 3.5mm cable. You can get these in store, or at least I did.

Driving around with headphones isn't exactly legal in some places, I prefer the earbuds for discretion.
