in Medical Practices today?

Introduction

• A stethoscope is acoustic medical equipment that
  is used for listening to the internal sounds in
  the human body.
• Typically it is made of a small disc shaped
  resonator and two tubes connected to the ear
  pieces.
• Mainly it is used to listen to lung and heart
  sounds by placing the disc against the chest. It
  can also be used to listen to the sounds from the
  intestine and arteries and veins.
• When used in combination with a sphygmomanometer,
  it is used for measurement of blood pressure.

Stethoscopes Types

• Acoustic

• Acoustic stethoscopes are the most common kinds
  and are familiar to most people. They operate on
  the transmission of sound from the chest piece.
  Air filled hollow tubes to the ear pieces.

Electronic
An electronic stethoscope overcomes the short
comings of the acoustic one by electronically
amplifying the sound levels. These types
of equipment hence require the conversion of
sound waves to electronic signals which are later
amplified and processed to make them
optimal for listening.

• Recording

• Some stethoscopes use a direct audio output that
  can be used with external recording device
  such as a laptop. In this way you can
  also compare the current recording with a
  previously recorded signal and
  improve your diagnostics.

Fetal
Fetal stethoscope is an acoustic stethoscope that
is used to listen to the sounds of the fetus.
It is used to diagnose any abnormalities in
pregnant women.
Doppler
This device is used to measure the Doppler effect
of ultrasound waves reflected from the various
organs of the body. Motion is detected by the
change in frequency. It can be used in dealing
with moving objects such as heart beats.
