man-made-noise

It is noise that simulates the spectra of natural settings, without man-made noises.

At low frequencies, for example, atmospheric or man-made noise can mask antenna inefficiency.

To that end, meticulous care was taken not to include man-made 'noises off' from the likes of cars and aeroplanes.

They were also limited by the use of human ears to discriminate man-made noises from the oceanic background.

These names are noises, man-made noises for the Infinite.

An hour or so later I heard the first man-made noise of the day, the gentle chug of a small outboard.

Today all man-made noise was drowned by the chatter of the swollen river running beside the terraced garden.

Due to the potential for both natural and man-made noise, numerous techniques continue to be developed to deal with the interference.

The project focuses on radio frequencies that automated detection systems ignore due to the prevalence of man-made noise.

Through the wind and the distant man-made noises came the rush of water.
