one of the basic methods of examining internal organs by listening to the sound phenomena produced in them. Listening to the heart was first introduced in the second century A.D. by the Greek physician Aretes. The French doctor R. Laënnec (1819) developed the modern method of auscultation by employing for this purpose a “medical tube,” or stethoscope. More frequently a phonen-doscope is used for auscultation. This instrument is a hollow capsule with a sound-transmitting diaphragm that is placed against the body of a patient; rubber tubes connect it to the doctor’s ears.

During auscultation of the lungs one listens for the respiratory noises and the different rales that are characteristic of particular diseases. From the variation of the cardiac tones and the occurrence of noises, the condition of cardiac activity and presence of heart diseases can be ascertained. Arteries may be listened to in order to determine changes in the blood pressure. The presence of peristalsis of the stomach or intestines can be established by auscultation of the abdomen, and in pregnancy the heartbeat of the fetus can be detected.

In veterinary science, auscultation is employed in the diagnosis of diseases of the cardiovascular, respiratory, and gastrointestinal systems of animals. In direct auscultation the investigator places his ear against a sheet or a towel covering the portion of an animal’s body being examined; indirect auscultation is carried out by means of a stethoscope or phonendoscope. Instrumental auscultation was first employed in veterinary science by the Hungarian scientist J. Marek in 1901. In the USSR the auscultation method was perfected by the veterinary scientists K. M. Gol’tsman, N. P. Rukhliadev, A. V. Sinev, A. R. Evgrafov, G. V. Domrachev, V. I. Zaitsev, P. S. Ionov, and I. G. Sharabrin.

The fundamental cardiac sounds S1 (heard as a "lub" sound) and S2 (heard as a "dub" sound) are usually found in an auscultatory recording as characteristic components of relatively high energy.
These include tachycardia, bradycardia, hypotension, a water-wheel or mill-wheel murmur (a characteristic splashing auscultatory sound due to the presence of gas in the cardiac chamber), shock-like picture, cardiac arrest, crackles, wheezing, tachypnea, hypoxemic respiratory failure altered mental status, focal neurological deficits, syncope, coma, crepitus in superficial vessels if skin is involved, and bubbles within the retinal arteries.
COPD was diagnosed according to generally accepted criteria [9-11] on the basis of a typical disease pattern (long-standing moist cough with sputum discharge, intermittent fever, crescendo dyspnea accompanied by poor exercise capacity, which is preserved in the absence of disease exacerbation, typical auscultatory pattern in the lungs), medical history data (typical exacerbations of the disease), and X-ray findings (the presence of obstructive pulmonary emphysema, pulmonary fibrosis, change of the lung pattern, etc.), as well as on the basis of the examination results of the external respiration function (obstructive or mixed type of respiratory disturbance with a progressive decrease in forced expiratory volume^.
For the determination of overweight and obesity, we used the body mass index (BMI) and, in addition, the auscultatory method for measuring blood pressure.
Arterial blood pressure was ascertained using the standard cuff technique with a mercury sphygmomanometer placed on the left forearm and measured with the auscultatory technique.
The Finometer Pro meets the Association for the Advancement of Medical Instruments accuracy requirements for automated sphygmomanometers, with the precision of results comparable with those published for auscultatory techniques.
The ABPM recording was performed using the auscultatory mode of the validated Schiller BR-102 plus (Schiller AG, Switzerland).
CHD was clinically diagnosed with auscultatory murmur heard by using stethoscope over cardiac area of the chest and was confirmed by echocardiography.
(16,17) Auscultatory percussion (method of Guarino) might also have some value for detecting small effusion.
Blood pressure was measured on the left arm according to the auscultatory method with a mercury-column sphygmomanometer (auscultatory method, Vasquez-Lubry[R] sphygmomanometer-Germany, Littman stethoscope-USA).
