Question GS 450 h, year 2009 - short horn type noise heard only inside the car.

When stopped at a traffic light (brakes pressed) I heard a muted short horn type sound (Just like a short split second horn sound). At first I thought the car behind was doing it however soon I realised that it was my car. I cant her anything from outside - the intermittent noise comes at a random interval and can be heard from inside the cabin. This kept happening whenever I stopped the car (drive mode and with brake pressed).

There are no alarms or indicators on at present.

What could be be? Please help if anyone has any idea.

Thank you.

Could be the brake booster problem:
