Step-by-step explanation:
The loudness of a murmur is usually associated with the size or grade of the murmur. Murmurs are graded on a scale of 1 to 6, with 1 being the softest and least severe, and 6 being the loudest and most severe.
For example, a grade 1 or 2 murmur may be barely audible and not significant, while a grade 4 or 5 murmur may be loud and indicative of a more serious underlying condition.
Phonocardiograms or auscultograms can be used to record and analyze the loudness and characteristics of murmurs using specialized electronic stethoscopes.
