The term describing muffled heart sounds, jugular venous distension (JVD), and narrowing pulse pressure is "cardiac tamponade." This condition occurs when fluid accumulates in the pericardial space, exerting pressure on the heart and impairing its ability to pump blood effectively. The classic signs of cardiac tamponade are often summarized as Beck's triad, which includes these three clinical findings.
There is a pericardial space present in the heart. This space consists of fluid called pericardial fluid. This fluid is responsible to decrease the friction during the contraction and expansion of ventricles. When the amount of this fluid increases, the intrapericardial pressure increases. This results to the condition when the atria and ventricles fail to relax normally. This condition is the condition of cardiac tamponade and the ecg you study to get a brief knowledge on the above condition is cardiac tamponade ecg.
Sounds can be muffled when something intercepts the sound wave (lets say a blanket) and the sound waves can only get through a little bit. You can't hear the sound clearly but can still hear it, so it is muffled!
If you are manually taking a blood pressure measurement using a sphygmomanometer and stethoscope, the sounds you hear between the systolic and diastolic blood pressure are called Korotkoff sounds, and they are muffled "whooshing" sounds heard with each heart beat and are thought to be caused by turbulent blood flow through the blood vessel caused by partial occlusion by the cuffed sphygmomanometer.
The change in sound heard through the stethoscope during blood pressure measurements is primarily due to the Korotkoff sounds, which occur as blood begins to flow through the brachial artery when the occluding pressure of the cuff is released. As the cuff pressure decreases, these sounds transition from muffled to distinct tapping noises, indicating the systolic blood pressure when the first sound is heard and the diastolic pressure when the sounds disappear. This method allows healthcare providers to accurately gauge blood pressure by listening for these auditory cues.
When you yawn, the muscles in your ears and throat relax, which can temporarily affect your hearing by changing the pressure in your middle ear. This can make sounds seem muffled or distant until the muscles tighten back up.
Guitar sounds can become muffled due to a buildup of dirt, dust, or sweat on the strings or fretboard, or if the strings are old and worn out. This issue can be resolved by regularly cleaning the strings and fretboard, changing old strings, and adjusting the guitar's setup if needed.

Puffins make loud growling calls usually from underground which sounds like a muffled chainsaw. The chicks "peep" for food from parents.
I told the repair service that the dishwasher made so much noise that I have to close the kitchen door to muffle it.
"Sounds Muffled???" I suspect you have a collapsed catalytic converter that has partially blocked the exhaust. Tap on the converter and muffler with a rubber mallet and listen if anything sounds loose. This might have had something to do with the burned valve too.
