Not even- A loud series of electronic beeps interrupted her thoughts.

An electronic beep announced that the tricorder had found something.

An electronic beep from the sensors caused his pulse to race.

He heard the electronic beep of the machine being turned off.

It stopped abruptly, then she heard the electronic beep of an answering machine.

An electronic beep came from elsewhere in the chamber, followed by a female voice.

She dialed the number and there was an electronic beep at the other end.

It gave an electronic beep, and snapped shut behind him, on a spring.

After a few electronic beeps and clicks, a ringing came across the line.

The room was filled with an electronic beep, then with the sound of a dead man's voice.
