During a flight many time as the aeroplane gains height and the air pressure outside the plane reduces but is supposedto be maintained in the cabin, still evry time l felt these changes on my ear drums? Can any E N T specialists or flight expert answer this?

Above 8000 feet it maintains the pressure to 8000 feet. But as the plane descends, the pressure will rise back to sea level.
That is why you feel it most when you descend (not ascending). ==== Also the pressure is equalized through your nose. Some people equalize more easily than the others. Try chewing a gum as the chewing action make the passage move and let the air pass by.
Good Luck.

The cabin pressure still changes, just not as much as it would if the aircraft were not pressurized. Cabin altitude varies typically between sea level pressure and 8,000 feet.

Cabin pressure is generally maintained between 6000' & 8000' the discomfort u describe is usually felt during the transition to or from cabin altitude.
This can be exasperated by a rapid descent from criuse altitude to an actual altitude below cabin altitude.
Ear drums r extremely sensitive to non-standard pressures u may have noticed similiar discomfort if u have ever swam or dived under water.
Try yawning, swallowing or chewing, this can help equalise the pressure in ur inner ear. Also if possible avoid flying if u have any kind of head cold or other sinus infection.

The cabin of most commercial jetliners is pressurized to 8,000 feet. So, you will feel the change in air pressure between sea level and 8,000 feet, but it will not change beyond that. The aircraft maintains the pressure at 8,000 feet even when it is at 35,000 feet.

The pressure is maintained at the equivlent of 8,000 feet height during flights. During climbs and descents the differential pressure, prior to stabilising can be felt in the ear drums. A slight cold or a blocked ear canal due to infection etc., can induce discomfort. Remedy is either to swallow hard or pinch your nose and blow hard so that your ear canals open up. If this is a chronic problem with you, try using some ear drops prior to your flight.

the air pressure is not maintained at sea level pressure but is allowed to decrease to an altitude equivalent to approx. 8,000ft.

On most commercial jetliners cabin pressure is controlled by the computer & is generally raised or lowered at a rate proportional to aircraft is climb or descent rate. This is done to avoid sudden transitions from one cabin altitude to another. Airliners r not maintained at sea-level air pressure due to the undue strain this would put on the airframe from the pressure differential between the outside & inside air pressures. In the Boeing 737-800 the cabin air pressure will be somewhere between 6000 & 8000 at altitudes typically flown by airliners. The Boeing 787 & the Airbus A380 will maintain cabin pressures between 5000 & 6000 feet a their highest operating altitudes.
