Allardyce cupped his ear in disbelief after West Ham were booed off the pitch at Upton Park, despite ending a three-match losing streak at home to Hull.
"I've not experienced that before in the time I've been in the game," he said in the post-match press conference.
"Obviously, for us, today was all about coming off with three points, whether we played brilliantly, indifferently or not so good. It was about getting the three points.
"The lads have gone about it and, when they've come off the field, they've got the three points and that is what matters.
"I have to remind everybody about the situation of playing against 10 men and the two examples of how difficult to beat 10 men.
"We were brilliant playing with 10 men when we beat Cardiff 2-0 and we played here against Swansea City for 65 minutes with 10 men and they didn't score and we won the game.
"Hull City played with 10 men, kept the ball well and we beat them. That's what you've got to do. The examples prove just how good we are. We beat them, that's the most important thing."
Asked about cupping his ear after the final whistle, Allardyce said: "I did it because I was hearing booing, I couldn't quite believe it.
"I'd seen something I've never seen before. Nothing surprises me, I suppose.
"I can't understand it, to be honest. We've got a difficult situation and it must be frustration."
