Feel yourself becoming transparent, as it were, without the solidity of a material body. Now allow the noise, or whatever causes a negative reaction, to pass right through you. It is no longer hitting a solid “wall” inside you. As I said, practice with little things first. The car alarm, the dog barking, the children screaming, the traffic jam. Instead of having a wall of resistance inside you that gets constantly and painfully hit by things that “should not be happening,” let everything pass through you.
