Well, the sound of an ambulance siren is about 120 decibels.

Outside on the street, an ambulance siren wailed to the night.

In the distance, they could hear the ambulance siren whooping.

In the distance, we heard the sound of an ambulance siren.

Two minutes later the ambulance siren had roared to life and she was on her way.

And he could hear an ambulance siren in the distance as well.

He heard an ambulance siren starting up far in the distance.

Here and there a cry of a woman, a man, an ambulance siren carried on.

Then, somewhere in the stillness, she heard the ambulance siren.

The Other smiled as she walked away from the flashing lights and ambulance sirens.
