I find it very convenient to have these microphones, as I suppose you would call them, catching your words without talking into them directly as you have to do in the telephone and then at the other end emitting the words without the use of an earpiece, from the box itself, as if from a megaphone horn. Miss Haversham, this is Dr. Klemm. There is a Dr.

The telephone receivers connected to the two microphones are mounted close together on an instrument board on the bridge of the ship. The two instruments are used when it is desired to determine the direction from which the signals come. If the sound is stronger in the 'phone on the right-hand side of the ship the commander knows that the signals are coming from that direction.

We saw a light and heard guttural shouting below and the cracking of a gun as a few bullets spattered against the roof of our chamber. We heaved down our gas bombs and covered over our shaft. Within a few hours the light below went out and our microphones failed to detect any sound from the rocks beneath us.

Then the computers clicked and hummed and performed incomprehensible integrations, and out of their slot-mouths poured billowing ribbons of printed tape. Men read those tapes and talked crisply into microphones, and their words went swiftly aloft again. Down by the open eastern door of the Shed at the desert's edge, Sally Holt and Joe's father waited together, watching the sky.

But there seemed no other sound. There was no other motion. There was absolute stillness all around. But when Calhoun switched on the outside microphones a faint, sweet melange of high-pitched chirpings came from tiny creatures hidden under the vegetation of the mountainsides. Calhoun put a blaster in his pocket and stood up.

Any arrangement imaginable may be given the transmitter and receiver; but, aside from the fact that the ones just indicated are the simplest, they give results that are at least equal, if not superior, to all others. We have stated that the nail microphones are the simplest.

Brent's thick lips hardly moved, a characteristic that Crane found infuriating because that was the way shady characters talked into Senatorial investigation microphones and it looked pretty bad. But Brent's words came quite clear: "Routine business, Senator an honest effort to get a day's work done." "You mean to tell me the meeting that's been set up here is routine?" Brent shrugged.

It had a pair of black sockets in its head, which Mike took to be TV cameras of some kind. It had grillwork on either side of its head, which probably covered microphones, and another grillwork where the mouth should be. There was no nose. "What the hell?" asked Mike the Angel of no one in particular. "I'm Snookums," said the robot.

"They tell me slaves are never permitted to enter it. Maybe, but they have the place bugged to the ceiling all around." "Bugged? What with?" Shatrak asked, and Erskyll was wanting to know what he meant. No doubt he thought Ravney was talking about things crawling out of the woodwork. "Screen pickups, radio pickups, wired microphones; you name it and it's there.
