I worked four flights on aircraft X on Date as the A flight attendant. Shortly after take off; both C and I noticed there was a very loud noise coming from the left side front entry door next to my right ear sitting at the jump seat. Once we reached 10;000 feet; I asked C to request assistance from one of our deadheading captains to access if the door seal is intact. That deadheading Captain heard the noise and access the door seal to be safe. I called flight deck and inform our Captain of the situation and he said the door look safe from their indicators too and would call for maintenance to meet us in ZZZ.Once we landed in ZZZ; the Captain showed me a piece of metal that maintenance confirmed belongs on the outside of the door hinge area. Maintenance told us he couldn't do the repair and it must wait until end of day at ZZZ1. That noise got louder with each flight and by the third flight; I was unable to hear the accent 10;000 foot chime and was able to make the PA only because I visually saw the light. I warned B of this so when both C and I couldn't hear the 10;000 foot chime on the fourth flight; B made the PA from the back for us. B and C used their apple watches and were able to record the noise level at up to 107 decibels during cruise. I have pictures of this. Half way through the work day I developed a severe headache and by the end of the day my hearing; especially my right; feels compromised like it has a cotton ball in it. I have learned from crew working on that same aircraft today that the noise problem is still there today.
Flight attendant reported excessive noise from a main cabin door in flight. The measure decibel level was or 107Db and was causing pain to the Flight Attendant.
