Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
In order to listen to the lungs from the back the patient is asked to move their arms forward to prevent the scapulae (shoulder blades) from obstructing the upper lung fields. These fields are intended to correlate with the lung lobes and are thus tested on the anterior (front) and posterior (back) chest walls.
Understanding Lung Sounds 3rd edition (2002) by Steven Lehrer is a book and audio CD that guides the student through the skills of lung auscultation. It provides a complete overview of lung examination, anatomy, physiology, and pathology.
Stridor (from Latin 'creaking/grating noise') is an extra-thoracic high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. It is different from a stertor, which is a noise originating in the pharynx. Stridor is a physical sign which is caused by a narrowed or obstructed airway.
External noise from the environment or internal noise from the patient (e.g. breathing) make heart sound segmentation challenging. Feature extraction: Having identified the phases of the heartbeat, information from the heart sound is extracted that enters a further classification stage. Features can range from simple energy-based approaches to ...
Lung ailments such as Chronic Obstructive Pulmonary Disease (COPD) cause the narrowing of airways in the lungs, limiting airflow and causing shortness of breath. Due to the limitation of airflow the VRI breathing pattern differs from that of a healthy individual. The patterns show asynchrony between lungs; with peaks in vibration energy difference.
In human speech, egressive sounds are sounds in which the air stream is created by pushing air out through the mouth or nose. The three types of egressive sounds are pulmonic egressive (from the lungs ), glottalic egressive (from the glottis ), and lingual ( velaric ) egressive (from the tongue ).
