There was a considerable amount of surface noise. The signal processors filtered most of it out, and every few minutes Jones switched them off his channel, getting the sound unimpeded to make sure that they weren’t filtering too much out.

That was a problem with computers, really a problem with programming: you’d tell the machine to do something, and it would go do it to the wrong thing.
