The rules on attacking creatures from hiding are:
When a creature can't see you, you have advantage on attack rolls against it. If you are hidden–both unseen and unheard–when you make an attack, you give away your location when the attack hits or misses.
Is your location "given away" to a blind & deaf creature that otherwise has no way to percieve you normally? What about if it is not the one being attacked?
(For clarity, the creature does not have truesight or blindsight or any other special senses. If it were next to you it could perceive you by touch, but in this situation it is not)
To that creature, you will be "unseen and unheard" before you make the attack, during it, and after it.
I think that this hinges on exactly what "give away your location" means. It could mean "all creatures in the combat know where you are", or it could mean "all creatures capable of perceiving you know where you are", or something else.

Yes, to an extent
The creature would certainly feel a successful attack despite being blind and deaf! A missed attack? Well, he may feel the 'whoosh' of a blade or arrow passing by but this could require some DM adjudication (perhaps a perception check at disadvantage but only if the creature is aware of a potential danger).
If this was a melee attack that would certainly be enough to give away a rough location. For a ranged attack this becomes much harder and as a DM I would rule that the creature would only know the rough direction that the attack came from but probably not the distance (and not enough for a ranged counter-attack).
Either way, the creature would certainly know that someone is out there trying to hurt them.
If the creature was not the one being attacked:
In this case I can't really see how the creature - if they have no other sense at all - could possibly know the attacker is there (unless the attack happens close enough, and the creature is aware of potential danger, to maybe feel the 'whooshes' of swinging blades as described in the other case).
