I've barked at em , clapped my hands, thrown stuff even . Bumping em by noise isn't gonna hurt much . Most of the time they aren't really spooked but just get cautious and move off . Letting them smell you is what does the most damage . I wouldn't worry about it . Lots of deer on the woods and in your situation of trying to get your first antlered deer I wouldn't sweat it . Just continue to hunt the stands with the best winds and the best entry and exit and it'll all work out .
