This stethoscope is renowned for its acoustical excellence. The Rappaport-Sprague Stethoscope has been clinically shown to deliver more faint heart sounds and murmurs than other stethoscopes and attenuate sounds in the upper frequency area as well. Adjustable binaural tubes are comfortable and aid proper sound transport. Chrome-plated hose clip keeps the stethoscope hoses from rubbing. Soft eartips provide user comfort and also prevent sound interference.
