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.
What you're describing sounds suspiciously like a worn compressor.
Pressure Sounds was created in 1994.

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.
The sounds heard while measuring blood pressure in this way are called the Korotkoff sounds, and undergo 5 phases: # initial 'tapping' sound (cuff pressure = systolic pressure) # sounds increase in intensity # sounds at maximum intensity # sounds become muffled # sounds disappear
