This is because the pressure in the cuff is high enough such that it completely occludes the blood flow. This is similar to a flexible tube or pipe with fluid in it that is being pinched shut. If the pressure is dropped to a level equal to that of the patient's systolic blood pressure, the first Korotkoff sound will be heard. As the pressure in ...
The rush of blood from these veins to the brachiocephalic vein can cause the vein walls to vibrate, creating a humming noise which can often be heard by the subject. Typically, a peculiar humming sound is heard in the upper chest near the clavicle , emanating from the supraclavicular fossa just lateral to the sternocleidomastoid muscle ...

Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to clear the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen therapy, or air travel.
And while over-the-ear headphones can help close off more outside noise (than earbuds), it’s still important to keep the maximum volume at 70% or less to maintain hearing health. __wf_reserved ...
