I'm another one: UK based Emergency Medicine doctor! I had a go at an electronic stethoscope, mainly to help overcome the considerable background noise in my Emergency Department. I started with a

Any old cheapie works I suspect. In our hospital wards they buy packs of 10 for the nurses to use, with each stethoscope costing only a couple of bucks. But actually they work pretty well, especially

This seems like a great project for me to experiment with...can any of you for here recommend a low priced stethoscope suitable for non-medical grade play time experimenting? Sorry dont mean to

Nice to meet you too, Doctor paralogic! I've never knowingly met a medical practitioner on this forum before but perhaps others have been here. As this is a mic BUILDERS forum I thought I'd better

I would recommend the PUI5024 (the one you mentioned). I would also use PIP power, not Phantom. We don't need 48V getting near a patient's body. I am wondering if a mount for it similar to a current

No. This is a fantasy. The acoustic load of each capsule is different and there are phase issues. >

Thank you to everyone who shared their experiences. It was also great to meet Dr. Dent. Wouldn't you recommend a POM5024 HD for quality sound? Is eliminating noise with electrets really as simple as

As for handling noise, it might be worth trying to use a "dummy" capsule wired in parallel but facing the opposite direction with the sound blocked.

Dr. Paralogic, I think Dr. Dent has your answer. You don't even need an Unobtainium supa WM61A capsule as most of the 6mm capsules are good to at least 2kHz.

This is a very interesting thread for me, a micbuilder and a physician (geriatrician). I have tried building a couple of electronic stethoscopes over the years. In the first attempt, I built a kit

And Sennheiser had a mic back in the 1960s with a frequency response extending to 0.1 Hz. It was an omnidirectional condenser mic using low-voltage RF bias on the capsule. Using RF bias, there is much

Thank you for all the explanations. I have a littmann core stethoscope, it is actually quite successful, but it stores the recorded sounds on its own server, so I cannot create a dataset for signal

If the aim is to make a 'better' stethescope, could you tell us * what is?bad about present ones * annoying stuff * important stuff that could result in misdiagnosis If it's just a fun thing, I

I made several stethoscope mics. Just a Omni electret capsule glued into a stéthoscope. About 10Hz- >20000 kHz. You hear the same as with a stethoscope thus with body noises. No need to adjust the

That sounds like an interesting project.? I'm still amazed that doctors get so much information from such primitive passive technology, and wonder how much better they'd do with something better

Far be it for me to rain on your parade, but if you're interested in seeing what the state of the art is, I recommend a little excursion down patent lane. You'll easily find modern patents with noise

-- I am working on my own electronic sthethoscope design. Great project. If you were going to look at the waveform then you might need to go down to 1 Hz or lower. But if you are going to just listen,

Transducers used in body exploration require a certain amount of filtering and dynamic processing. Amplification in itself is generally not too difficult, but the frequency response must be tailoed to

Hi everyone, I am a cardiologist. For a fun activity, I am working on my own electronic sthethoscope design. Heart sounds are low frequency and low intense sounds. (About 20 to 1200 Hz). Are listened

Somewhat off topic… I'm not sure whether absolute polarity is audible. I’m willing to believe that a trained listener can hear it. I don’t think I can. I can tell when polarity is switched, but
