A Grade 3 murmur should be readily heard with a regular stethoscope. Although the room should be quiet for all auscultation tasks, an "extremely" quiet room and an amplification stethoscope should not be necessary. The bell of the stethoscope is usually used to listen to heart murmurs, but the stethoscope needs to be on the patient's chest.
