Which term describes extra heart sounds that are produced as a result of turbulent blood flow that is sufficient to produce audible noise?

Explanation:
Murmur is the term for an audible sound caused by turbulent blood flow. When flow through a valve or within a chamber becomes disrupted—such as with valve stenosis, regurgitation, or high-flow states—the turbulence creates vibrations that we can hear with a stethoscope. These sounds can occur in systole or diastole depending on the underlying lesion. This differs from a gallop, which is an extra heart sound (S3 or S4) related to filling dynamics rather than turbulence, and from JVD or NSR, which are signs of venous pressure and a normal rhythm, respectively. So, the sound produced by turbulent flow audible as noise is a murmur.
