Abstract
A noise attenuating stethoscope is coupled to a noise attenuating headset having first and second sound attenuating ear cups which are coupled to the ends of a headband. A pair of ear tubes extends laterally through an aperture in the side of each ear cup and includes an ear piece coupled to each end thereof. A resilient sealing device is positioned within the aperture of each ear cup and surrounds the outer surface of each ear tube to form a seal between the ear tubes and the ear cups to attenuate the transmission of sound through the apertures and for permitting the ear tubes to be both angularly deflected and laterally displaced with respect to the ear cups. A sound delivery tube couples a sound pick up to each of the ear tubes to transmit sound from the sound pick up to the ear tubes. The noise attenuating stethoscope may further include a quick-connect coupling between the sound pick up and the sound delivery tube.
