I think you are working to a false premise.
It is not actually the sensitivity of the microphone that is they key to this - you can take any half decent mic & keep turning it up. Sure, there will be some noise floor, but this is almost irrelevant.
What is different is perception.
The human ear is controlled by the human brain. Aside from the fact that ...
For things like this I've used heavily cooked macaronis for the gooey sound in combination with messing around with a spoon in a jar of jam, and biting a special kind of big green grapes for the bursting of the eyes. Squeezing oranges, lemons and pomelos gives awesome squishy sounds as well. Mind you, the eye-sockets are hollows just like the mouth, there is ...
I listened to the file several times and couldn't hear it. In a spectrum analyzer, I can see what you're referring to. It's at -90 dB, so you'd have to crank up the volume pretty far to be able to hear it.
Because the speech volume in the recording is at -20 dB, most people will set the volume to a level where that's comfortable to listen to, and the beep ...
Unless you are recording in a very controlled environment, I would recommend a contact mic (which is, ultimately, a better-sounding stethoscope). A standard capsule-based mic will likely generate too much noise (or pick up noise from the surrounding area) because you'll need to turn it up significantly to pick up a pulse.

Do you have Native Instruments Kontakt? If you do, you can get Atom Hubs Microbiology.
It's only 10€.
Human body consists mostly of water, so try to find suitable underwater sounds, drains, squishes...unless your aim is to go totally realistic?

Panasonic got out of the electret microphone capsule business several years ago. But certainly there are many vendors of similar commodity electret capsules out of the usual places. The Panasonic WM-6x series was legendary for a couple of reasons: They were dirt-cheap, and they had pretty flat frequency response.
But they were not noted for having very ...
Protools has a "Split Silence" function which can be used to seperate out all elements where the audio level does not reach a particular threshold. Assuming that most of the audio is actually speech, then this is where I would start. Once you have all the speech segments, you can then 'shuffle' them down to a single region which you can then export.
Unfortunately boosting the signal you have is unlikely to help - where you don't have the information in the signal you can't really create it.
As you have already seen, while DSP's can do a lot to increase the distinction between noise floor and signal, and between unwanted frequencies and speech you are ultimately limited by the quality of the recording.
These should be very good.
A cheap soldering iron off eBay, and 6 wm61a's for about 12 UKP (in case you have an accident)...
I'm just in the process of getting a few more of these mics for binaural recordings (proper binaural, not stereo) I've used them in the past, and are very good.
I'll be experimenting with these that I get this time round, in about a ...
Some weeks ago I put an inexpensive electret capsule inside the tube of a stethoscope and recorded my stomach and my heartbeat. I paid about 2euros for the capsule and the recordings turned out to be pretty usuable.
It's not clear what type of gear you already have.
But check out this video with Diego Stocco.
He uses a stethoscope and I think he inserted a lavalier microphone in the tube.
Not sure, but worth a try.
