Technically yes but what I mean is: Are there organisms that shape that sound into a tightly focused beam, to be able to only address the receivers they aim at?

Bats, dolphins. Dolphins even used focused beams of high intensity sound to stun fish, I believe.
Are you talking about echo location? I don’t believe this is understood to be a form or communication?
I’m being lazy here, but isn’t this what happens when you cup your hands over someone’s ears to whisper? Or ever just turn to the person and talk quietly.
