Phonography

Phonography (from the Greek words phono - “sound” and grapho - “write”) is a method of recording sound vibrations used in medicine.

The essence of the method is the recording and subsequent analysis of sounds produced by the internal organs of a person. For example, when auscultating (listening with a stethoscope) the heart or lungs, the sounds that occur when the heart contracts or air passes through the bronchi and trachea are recorded.

Phonocardiography allows you to record the sounds of cardiac activity and analyze the characteristics of the heart rhythm and heart sounds. Similarly, phonopneumography makes it possible to assess the nature of respiratory sounds in the lungs.

Phonographic research is carried out using special devices - phonographs or phonendoscopes. The resulting phonograms are interpreted by a doctor to make a diagnosis and monitor the dynamics of the pathological process. Thus, phonography is an important diagnostic method in medicine.
