Lung Sounds Reference Guide
Our lung auscultation guide provides quick access to twenty lung or breath sounds. Our guide includes audio, listening tips and a waveform.
Repetition Training
As a supplement to our courses and reference guides, we provide auscultation repetition training. This training is available using courses or quick lessons.
Lung Sounds Lessons
Learn lung auscultation by taking our free courses These courses cover basic and intermediate levels of lung sounds. Use the table of contents below to review and access a course or lesson.
Basics of Lung Sounds
The goal of this basic course in lung sounds is to improve auscultation observational skills. We focus on describing important breath sounds and in providing recordings of each. Many students find that waveform tracings aid in learning lung sounds; we have included dynamic (moving cursor) waveforms with each lesson.
Lesson List

Intermediate Lung Sounds
The goal of this intermediate auscultation course is to expand your observational skills for breath sounds. The course lessons include voiced sounds: bronchophony, egophony and whispered pectoriloquy. We also provide lessons on several types of wheezes, crackles and stridor. Each of these lung sound lessons includes audio, text and dynamic waveform.
