To the receiver, the signals of other users will appear to the demodulator only as a low-level noise.

In mobile audio, use of a line driver allows an amplifier's gain to be set lower, reducing low-level noise.

A new study by researchers from Cornell has found that even low-level noise in an open-style office setting can lead to measurably higher levels of stress.

The various low-level noises produced by the hands and the objects generate a quiet, John Cage-style, surround-sound concert.

Digital sampling introduces quantization error that manifests as low-level noise added to the reconstructed signal.

The company has also done research on how noise-canceling headphones can help decrease symptoms of jet lag by reducing low-level noise that interferes with sleep.

"A lot of what is going on, to the public at large it is low-level noise," said Russ Schrieffer, a top Giuliani campaign official.

Not only that, but employees in offices with low-level noise made fewer efforts to adjust their workstations, making them more susceptible to problems like repetitive strain injury.

Each signal then travels through a compander, where the signal is compressed to further eliminate low-level noise and is then expanded again.

LOW-LEVEL noise problems in rooms can often be controlled by using sound-absorbing materials on the walls, floors and ceiling.

Care must also always be taken when amplifying low-level noise to keep out spurious signals, such as power line hum and unwanted broadcast transmissions, and to avoid adding bias during acquisition and amplification.

There was continuous, low-level noise in the room, consisting of the rumble of the presses, the chatter of telegraph sounders from the back, and the intermittent buzz of conversation punctuated by yelling or a question called from the central desk.

Converting an analog signal to digital form introduces a constant low-level noise called quantization noise into the signal which determines the noise floor, but once in digital form the signal can in general be processed or transmitted without introducing additional noise or distortion.

The constant low-level noise has been perceived by James Wierzbicki in his book Music, Sound and Filmmakers: Sonic Style in Cinema as perhaps a product of Henry Spencer's imagination, and the soundtrack has been described as "ruthlessly negligent of the difference between dream and reality".
