Mediate Auscultation and the Stethoscope

I found in a street marcket this record:

It was released in the 50's and it contain the samples of cardiopatology.

Also if it is very damage you can listen it here

SIDE A

SIDE B

auscultation (o-skuhl-TAY-shuhn) noun

   1. The act of listening.

   2. The act of listening for sounds made by internal organs,
      as the heart and lungs, to aid in the diagnosis of
      certain disorders.

[Latin auscultatio, auscultation-, from auscultatus, past
participle of auscultare, to listen to.]

   "Chest auscultation with a stethoscope will help detect
   any heart murmurs or harshness of the lungs."

Listening it immediately I thought how was important in medicine the the inner sound of our body and how little change in timber and rhythm can reveal so different kind of pathologies with out any visible symptom. 

In the centuries our ear help us in scheduling notes about the sounds of our body, and many things change of course with the invention of the stethoscope, symbol of our mental model of a doctor.

I was curious to know more about this argument and I found a very interesting Jonathan Stern article. Here are the abstract:

"The practice of mediate auscultation—listening to the body through a stethoscope—was at the center of new articulations of medical thought and practice in the 19th century. During that period, the stethoscope became the hallmark of medical modernity. This article offers a detailed examination of the work of RTH Laennec and other important writings on the stethoscope in order to argue for the centrality of a distinctive orientation toward listening in modern medicine. The development of mediate auscultation applied medical and scientific reason to listening, just as a particular practice of hearing the body became integral to everyday functioning of medicine. Mediate auscultation was thus an artifact of a new approach to reason and the senses, one based in a scientific mindset and a logic of mediation.
