Lung Sounds
Welcome to our lung sounds training introduction. We offer several ways to learn auscultation skills. Our courses are an ideal entry point for new learners. The reference guide is designed to provide quick access to abnormal sounds, with summary listening tips, audio examples and waveforms. The repetition training pages provide a methodology that helps some users memorize each type of lung sound. Finally, our newest offering are a series of interactive case studies in pulmonary problem-solving.
Course completion certificates are now available. Signed-in users must review all course lessons and then pass a graded quiz. Personalized achievement certificates can be printed and are automatically saved to the user's dashboard.
Definition
Lung sounds, also called breath sounds, can be auscultated across the anterior and posterior chest walls with a stethoscope. Adventitious lung sounds are referenced as crackles (rales), wheezes (rhonchi), stridor and pleural rubs as well as voiced sounds that include egophony, bronchophony and whispered pectoriloquy. Descriptions and audio recordings for all of these sounds are available on this website.
Reference Guide
Our auscultation guide provides quick access to normal, voiced and adventitious sounds. This guide includes audio recordings, listening tips and a waveform.
Lung Sounds Reference GuideLessons
Learn lung sounds with our lessons. These lessons cover basic and intermediate levels of adventitious lung sounds and voiced sounds. Use the table of contents below to review and access a course or lesson.
| Intro to Lung Sounds This free introduction to lung sounds module is designed to demonstrate our lung sounds lessons before a user decides to join our website. |
| 1 | Vesicular - Normal |
| 4 | Wheeze - Expiratory |
| 7 | Pleural Rubs |
| 2 | Bronchophony - Healthy |
| 13 | Stridor |
| 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. The anatomy pages use illustrations to reveal an example of each lung sound (anatomy not yet available on smartphones). |
| 1 | Vesicular - Normal |
| 2 | Crackles - Fine (Rales) |
| 3 | Crackles - Coarse (Rales) |
| 4 | Wheeze |
| 5 | Rhonchi - Low Pitched Wheezes |
| 6 | Bronchial |
| 7 | Pleural Rubs |
| 8 | Bronchovesicular |
| Intermediate Lung Sounds The goal of this intermediate course is to expand your observational skills when auscultating breath sounds. The course lessons include voiced sounds: bronchophony, egophony and whispered pectoriloquy. We also provide auscultation lessons on several types of wheezes, crackles and stridor. Each of these lung sound lessons includes audio, text and dynamic waveform. The anatomy pages use illustrations to reveal an example of each lung sound (anatomy not yet available on smartphones). |
| 1 | Vesicular - Diminished |
| 2 | Bronchophony - Healthy |
| 3 | Bronchophony - Abnormal |
| 4 | Egophony - e |
| 5 | Egophony - a |
| 6 | Whispered Pectoriloquy - Healthy |
| 7 | Whispered Pectoriloquy - Abnormal |
| 8 | Wheeze - Expiratory |
| 9 | Wheeze - Monophonic |
| 10 | Wheeze - Polyphonic |
| 11 | Crackles - Early Inspiratory (Rales) |
| 12 | Crackles - Late Inspiratory (Rales) |
| 13 | Stridor |
