Narrative:
Shortly after 10;000 feet on departure the door at 1L began making a very loud 'screaming' siren like noise. I notified the cockpit. They determined that since we were maintaining internal pressure inside the aircraft it was a door seal failure. They contacted maintenance and then told me nothing could be done. They suggested I stuff garbage bags around the door to stifle the noise. No help. The pilots said they could hear the noise in the cockpit and in their bunkroom. They refused to come downstairs to listen to the noise despite my pleas that they could not fully appreciate the unbearable sound unless they heard it for themselves. They tried several altitudes to see if that would quiet the noise. No help. The noise continued for the entire flight. It was like sitting next to a police car siren for 9 hours! Three flight attendants experienced headaches and ringing in their ears. The noise did not stop until we were on final approach.
