A new stethoscope designed by the Acoustical engineer Adrianus Houtsma can help the doctors in the critical situations when life and death hang in balance.

This new stethoscope cuts external noises and helps the doctors to diagnose the symptoms and further treatment better.

Earlier the external noises especially in the range of 80-85 db used to make the hearing impossible but this new device can operate in a 120 db environment.

Houtsma said that further work would focus on making this device more strong and rugged for real life use.

He and his colleagues will report there research in the meeting of the Acoustical Society of America and the Acoustical Society of Japan in Honolulu on December 2.
