In my previous post, I elaborated upon the physical issues that can be hazardous for public speaking like the lectern, sound system, or electrical failure, etc. Other than these issues, some other issues may also arise; issues related with the audience that needs to be taken care of in order to make our presentation better and impressive. Even after ensuring that all the physical arrangements are in order, the audience is also as per our expectation, there is a probability that they may lose confidence in you. They may get turned off by something said by you or by some of your remarks or your attitude towards them.
