If pressure is higher in the inside of the eardrum, the eardrum will pop. If pressure is higher outside the eardrum cave in.
to maintain equivalent air-pressure on both sides of the ear drum.
Eustachian tubes are part of our auditory system their function is to equalize pressure on both sides of our ear drum so that it can vibrate freely.
In a drum, the air sealed inside the drum vibrates and makes both the membranes of the drum plus and any small holes drilled in the sides of the drum. The vibrations get transferred to the air outside of the drum and then into your eardrums.
what are many have air pressure if the one drum is going up and other one is going down
both are used for hydraulic pistons to create pressure against brake rotor/drum or clutch disc
An ear drum bursts by water putting pressure on the back of it.
boiler drum diffferential pressure level calculation explained
The sound pressure wave is travelling down the ear canal, hits the area of the eardrum, which vibrates ... just like a drum! Sound pressure p = force F divided by area A.
as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.
I think a vessel is containing a fluid under high pressure whereas a drum contain a fluid with no or low pressure.
