A stethoscope head for a one-way stethoscope with a membrane. The stethoscope has a funnel or bell-shaped resonance body. A membrane and the resonance body enclose a resonance chamber that is interconnected to the air column in the lumen of a tube. A capsule of a soundproof material completely surrounds a distal region of the resonance body without contact, leaving just an opening through which the tube passes. A suspension element of elastomer material forms a mobile connection between the capsule and the holding ring attached to the peripheral rim of the resonance body. |
