Atarax – Stethoscopic Heart Sounds

This record is a study of Heart Sounds
Suggestions for Reproduction: The unique feature of this record is that it was produced so that it might be listened to with a stethoscope. It is suggested that one sit comfortably in his chair, hold the chest piece of the stethoscope in his hand and with the ear pieces in place, start the record, close his eyes, and listen. The loudness is then adjusted so that the spoken voice is just heard distinctly; this results in a normal level of intensity for the sounds and murmurs of the illustrations. The advantages of using a stethoscope are obvious: the doctor is in a normal frame of mind for listening to a heart, extraneous room noises are eliminated, many high frequencies are ruled out and the sounds seem to be concentrated on the chest piece.
It is advisable to not lift the needle until the band is finished, if an illustration is to be repeated, play from the beginning.
