What you can hear is probably the anti-theft horn.

Guessing about your battery is not really a productive way of assessing it.
Get in on charge for a 24 hour minimum.--Leave it for a couple of hours then check the battery voltage.--You should see at least 12.4 volts which will be enough to start the engine. ( with luck that horn noise you are hearing will have vanished. )

Let us know how you get on.---

Joining the battery.---Positive first then negative.
