The stethoscope is an acoustic medical device that allows hearing the internal sounds. The name of modification has been thought up by the scientist George Philip Cammann in 1852. The phonendoscope differs from a traditional stethoscope in existence of the strengthening hardly tense membrane sensitive to vibrations of a sound.
You, perhaps, are surprised, having learned that there is such medical measuring device as a stethoscope. In particular, this device is strongly used by modern health workers and doctors. Two of his bells have no membranes, and the third end is equipped with a membrane. In addition, if you are looking for a quality stethoscope suggests you visit Stethoscope Lab.

The membrane, or diaphragm, has to be flexible, strong and densely adjoin to a body.
Tips (or olives) happen to be rigid plastic and soft rubber or helium. The second, of course, it is better as are attached to a form of an acoustical pass of the user.
Metal tubes can be connected by the pulling together metal spring that, certainly, increases the convenience of use. Head of stethoscopes can be unary, double (bell/membrane), double membrane (big diameter / small), double with a corrugated head. Besides, there are stethoscopes for babies and children of younger age, and also fatally stethoscopes for pregnant women for listening of a fruit.
Phonendoscope is an older type of the device that is created for the wiretap of the internals of a human body.
