Abstract:
This paper discusses the design, development, and testing of an integrated compact digital stethoscope capable of performing body sound measurement and processing without the need of a personnel computer and hardware interface. The cost of the proposed device is a fraction of that of the data acquisition system used with current digital stethoscopes to collect body sound, such as lung sound, in a digital format. Preliminary testing of the device shows faithful reproduction of the body sound signals used. Not only the new design strategy saves hardware, space, and power consumption but also it allows for the signal processing and data interpretation in the same device. This is due to the proposed integrated design of the subsystems involved in the data acquisition process. It also has the capability of sending collected data to remote location through the Internet.
