What
is a stethoscope?
A
stethoscope is a medical device to listen to sounds within the human body. At
one end has a diaphragm, a vibrating membrane designed to capture sounds. The
diaphragm is connected to a hollow tube filled with air. The tube is divided
into two and ends at the headset using the doctor. The stethoscope can be
placed on the patient's chest to listen to your breathing or heart rate, or the
underbelly to hear the intestines as personal
care.
The
doctor holds medical
stethoscope on the patient's body, usually to listen to the breathing
or heart rate. When the heart beats or lungs fill with air, small sound
vibrations occur throughout the body. Stethoscope picks up these vibrations and
amplifies the diaphragm. The sound passes through the tube, and then
transferred him to headphones doctor. There are also electric stethoscopes,
using a type of microphone to capture and amplify sound. However, because these
may lose or distort parts of the sound, most doctors use the acoustic version.
