If your low-frequency hearing is OK, you’ll be able to hear fine with a standard stethoscope. The problem comes if you have hearing aids: it’s not always convenient to take them right out every time you need the stethoscope. But if you have behind-the-ear aids with conventional earmoulds, you can flip the moulds out quickly, leaving the aids hooked over your ears.
Admitedly, they do sometimes make a bid for freedom, especially if you have spectacles competing for over-ear space. So at the start of your working day, try toupee tape or little stickies to stick the aids to your head or ear.
