A system and method for automatically detecting an adventitious sound from a sound signal (24) formed of a plurality of successive sound waves received from a patient (11) including establishing at least one of a predetermined time interval and a threshold signal value (14a) based on an average signal value (20) of at least a portion of the sound signal, sequentially comparing (35) the sound waves to at least one of the threshold signal value (14a) and the predetermined time interval (23, 32) to identify a first wave having at least one of an amplitude at least as large as the threshold signal value and a duration falling within the predetermined time interval, and identifying an adventitious sound (37) when at least one consecutive wave following the first wave has at least one of an amplitude at least as large as the threshold signal value and a duration falling within the predetermined time interval.
