If your cat is hissing at strangers you can't stop your cat from hissing at them. The only thing I can think of that would stop a cat from hissing at someone is letting a cat get to know a person long enough that the cat isn't afraid of the person, and will therefore get along with him/her.
When I got my cat a few months ago my dog hated him, and my cat hissed a lot. Your cat might be territorial, or just isn't used to your new cat.
Normally you would hear a hissing sound accompanied by your cat being angry
A cat will make a hissing sound when it feels that it is in any form of danger. This sound is made to warn other animals or people off.
It probably means you have a black cat with amber eyes. Also, that black cat with amber eyes is also mad, frightened, or otherwise upset at you or something else. Look around. If the cat is clearly hissing at you, then you might want to take some action, like move away. Then you can find out what is wrong without being attacked. Hopefully.
Snakes. Geese, if you make them mad enough.
Some people think that spraying cats with water is good discipline but it doesn't honestly help. A hiss is a hiss as long as the cat is not attacking and/or being aggressive towards another cat. A hiss is normal and it is basically a warning towards the other cat. So to sum this all up, you don't really control a cat hissing, its natural.
when your cat hiss does it hurt them

Hissing means that the cat is scared and it is trying to defend its self so stay away if a cat starts to hiss and arch his/her back.
Obviously, it didn't agree with your cat!
very carefully
theirs no way for any one to stop a kitten from hiss... or an older cat.
See if the cat has ear mites.
