Music & Sound Theory
The measurable unit of time that organizes rhythm in music and clinical listening.
What is a beat?
A: The classic heart rhythm sound often described as “lub-dub.”
Q: What are systolic and diastolic sounds?
A: These sounds are produced by the movement of the intestines and are considered normal at 5–30 clicks per minute.
Q: What are bowel sounds (peristalsis)?
A: Dr. Duffy emphasized that this is not the same as listening.
Q: What is hearing?
A: The musical term describing how loud or soft a sound is.
Q: What is dynamics?
A: This side of the stethoscope is used to detect high-frequency sounds like heartbeats.
Q: What is the diaphragm?
A: The two phases of breathing you can hear during lung auscultation.
Q: What are inhale and exhale?
A: Dr. Duffy used his musical background to help students hear these accurately.
Q: What are heart sounds?
A: These are beats that are naturally stronger and stand out from the rest.
Q: What are accents?
A: A murmur occurs when this happens to a heart valve.
Q: What is it doesn't close all the way?
A: A raspy or “wet crackle” lung sound indicates this fluid-related issue.
Q: What is fluid or mucus in the lungs?
A: This practice involves using a stethoscope to assess body sounds and requires trained listening.
Q: What is auscultation?
A: In a 4-beat measure, this is how long beat one lasts.
Q: What is from when it's heard until the next beat?
A: This gallop rhythm sounds like the word "TENNESSEE."
Q: What is an S3 gallop?
A: This lung sound results from inflamed pleural surfaces rubbing together.
Q: What is a friction rub?
A: This part of the heart emphasizes the “LUB” sound more prominently.
Q: What is the apex?
A: This musical concept helps clinicians better detect subtle changes in bodily sounds by subdividing beats.
Q: What is beat subdivision?
A: The phenomenon where the second heart sound appears to split into two distinct parts.
Q: What is split S2?
A: High-pitched respiratory sounds that may occur on inhale or exhale due to constricted airways.
Q: What are wheezes?
A: The cognitive process of identifying multiple layers or fluctuations in a sound environment.
Q: What is identifying soundscapes?
