1. An auscultation device, comprising:
- (a) a chest-piece ergonomically shaped for single hand operation having a nonmetallic contact surface to be placed in contact with a subject, a microphone built into said chest-piece for detecting sound from said subject and converting said sound into an electrical signal, a plurality of frequency selective band-pass analog filters built into said chest-piece to eliminate ambient noise and emphasize bell sounds, diaphragm sounds, and a combination of bell and diaphragm sounds of said electrical signal depending on an operation mode resulting in an enhanced electrical signal, a controller build into said chest-piece for electrically controlling said chest-piece, operation mode selection means for selecting said operation mode, a wireless transmitter built into said chest-piece for wirelessly transmitting said enhanced electrical signal to a wireless receiver, a battery-based power source, and a status display built into said chest-piece for displaying information including one or more indications of said operation mode, said wireless transmitter, and said battery-based power source; and
(b) a wireless receiver piece for examination of said enhanced electrical signal, said wireless receiver piece comprising a built-in wireless receiver and a power source.

Abstract
An embodiment of an auscultation device can be constructed using electronic components to provide improved acquisition, processing, and communication of sound signals. An input device can be used for detecting sounds, and electrical signals representing the sounds can be processed and transmitted via Bluetooth and/or another form of wireless communication. Such embodiments can employ, at least in part, one or more of several commercially available wireless receiver devices, such as, without limitation, headsets and headphones, mobile phones, PDAs and/or other handheld devices, desktop, laptop, palmtop, and/or tablet computers and/or other computer devices and/or electronic devices.
