Bruit, also called vascular murmur, [3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema. It is thought to result from the heart beating against air-filled tissues.
Heart sounds of a healthy human female with a functional or "innocent" heart murmur after exercise. A functional murmur ( innocent murmur , physiologic murmur ) is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself.

Still's murmur is detected via auscultation with a stethoscope.It has a peculiar "musical", "resonant" or "vibratory" quality that is quite unique. [1] [2] It is generally most easily heard at the left middle or lower sternal border and the right upper sternal border, often with radiation to the carotid arteries, although other locations are common.
[18] [19] Abnormal sounds include: Wheezes, describing a continuous musical sound on expiration or inspiration. A wheeze is the result of narrowed airways. Common causes include asthma and emphysema. [20] Rhonchi (an increasingly obsolete term) characterised by low pitched, musical bubbly sounds heard on inspiration and expiration. Rhonchi are ...
Hamman's syndrome, also known as Macklin's syndrome, is a syndrome of spontaneous subcutaneous emphysema [1] (air in the subcutaneous tissues of the skin) and pneumomediastinum (air in the mediastinum, the center of the chest cavity), sometimes associated with pain and, less commonly, dyspnea (difficulty breathing), dysphonia, and a low-grade fever.
Rhonchi are coarse rattling respiratory sounds, usually caused by secretions in bronchial airways. The sounds resemble snoring. "Rhonchi" is the plural form of the singular word "rhonchus". [8] Stridor: Wheeze-like sound heard when a person breathes. Usually it is due to a blockage of airflow in the windpipe (trachea) or in the back of the ...
Auscultogram from normal and abnormal heart sounds. Heart murmurs are most frequently organized by timing, into systolic heart murmurs and diastolic heart murmurs. However, continuous murmurs can not be directly placed into either category. [1] These murmurs are due to blood flow from a high pressure chamber or vessel to a lower pressure system.
