| Summary: | 碩士 === 南臺科技大學 === 電機工程系 === 107 === This paper describes a development of a surround sound electronic stethoscope,
which split the monaural heart sound signal via transversal filters to produce a pseudo
stereo sound for both ears that enables the listener to differentiate the different sounds of
the heart easier.
Identify and determine the occurrence of various events by hearing is a natural
human instinct. For example, we make corresponding actions after hearing the thunder,
baby crying or a door opening.
In the clinical medicine application the stethoscope is used for a non-invasive
signal detection to listen to the sound of human body, especially generated from the
heart and lungs. Through a stethoscope, heart murmur, irregular heartbeat can be found.
The physicians can also determine whether the relevant organ is abnormal by hearing
the sound of air flow through the human respiratory tract and lungs.
