I would really disagree as a physician that's used a lot of random crap stethoscopes when I don't have one or in an iso room. Those disposable ones are different in what they pick up, some findings are louder others not detectable. Sure I can pick up some stuff like rubs and systolic murmurs but you aren't going to get more subtle findings like diastolic murmurs and fine crackles. Probably a combination of certain frequencies responding and also me being used to mine.
