	Nursing Unit Configuration and Its Relationship to Noise and Nurse Walking Behavior: An AIDS/HIV Unit Case Study
		Although the average number of beds on a typical unit is 25 to 30 beds (Velsey and Egbert 1994), unit size may range widely-from as few as six beds in intensive care to as many as 48 in a general medical unit.
		The average noise level at night was 60.25 dB on the radial unit and 59.63 dB on the rectangular unit, and the average day levels were 62.56 dB on the radial unit and 62.02 dB on the rectangular unit.
		If radial/cluster units are to be recommended for hospitals, however, efforts must be undertaken to enhance their wayfinding characteristics, and acoustical finishes and staffing costs need to be balanced against the need for improved care environments.

	Noise Blanking for High Q Loop Antenna
		Noise blankers work on impulse type noise and the aim of the system described is to provide a means to blank out this type of noise whilst still taking advantage of the feature of high Q within the loop.
		The output of this unit is fed via a switch in the blanking unit and with the switch selected for noise cancelling, the output is fed to the loop converter for mixing with the loop signal.
		The noise cancelling and noise blanking units are in separate metal boxes to the loop converter and the three are interconnected via BNC connector ended cords.

	Integral active noise cancellation section patent invention
		In particular, the active noise cancellation unit of the present invention interposes a speaker or speakers between an input microphone located upstream of the speakers and an error microphone located downstream of the speakers.
		While the active noise cancellation unit 10 of the present invention is ideally constructed to cancel the noise generated from a motor 16 or fan 14, it is similarly capable of canceling the noise generated from any component capable of producing unwanted acoustic energy or sound.
		Controller 15 is adapted to process the residual uncanceled noise detected by error microphone 17 and to adjust the output signal to speaker 19 in such a manner so as to enable speaker 19 to generate an acoustic output signal 27 sufficient to cancel the unwanted noise 23.

	Metropolis Records: Noise Unit
		Noise Unit is one of the many side projects from the highly prolific Bill Leeb, most notably known for his work in Front Line Assembly.
		Noise Unit first appeared in 1989 when Bill Leeb got together with Klinik's Marc Verhaeghen to release the currently unavailable Grinding into Emptiness, which was released as part of Wax Trax's industrial domination of the late eighties.
		Up until now, the Noise Unit sound was very similar to the style embraced by the mother band, Front Line Assembly: harsh caustic electronic music empowered with a steady dance beat.

		Fan-filter units (FFU’s) are used increasingly by the microelectronics industry to provide clean, recirculating air for the fabrication of integrated circuits.
		To determine the noise and vibration performance of the FFU’s, 9 units were tested, all of which were 2 feet x 4 feet.

	FAN FILTER UNIT NOISE SPECIFICATION AND
		The unit was operating in the center of a large room with no additional pressure load applied.
		For a cleanroom with 100% ceiling coverage, the noise level is 3 dB higher than that with 50% ceiling coverage, and 6 dB higher than that with 25% ceiling coverage.
		The noise in the mock-up room is 6 dB lower than that in the large cleanroom, because of the extra amount of sound absorption pre filter unit.

	Acoustic device with a noise reduction unit patent invention
		The noise reduction unit serves to combat noise in the resonance chamber, and includes first and second electro-acoustic transducers, a controller, and a sound-absorbing member.
		The noise-reduction circuit is operatively associated with the speaker for reducing noise in the resonance chamber.
		The second electro-acoustic transducer is mounted in the resonance chamber, is coupled to the controller, and is operable so as to generate a sound wave that corresponds to the second electrical signal and that counteracts a portion of the noise in the resonance chamber.

		Noise Unit is one of the many side projects from Bill Leeb, most notably known for his work in Front Line Assembly.
		Noise Unit was the name given one of the numerous industrial projects of Bill Leeb and Rhys Fulber, who together also helmed Front Line Assembly, Intermix, and Synaesthesia.
		In the meantime, Fulber departed to concentrate on his producing career, and was replaced by Chris Peterson; Leeb's various other side projects with Fulber, including Intermix and Noise Unit, fell by the wayside as the new teaming with Peterson took shape: Pro-Tech and the drum'n'bass-flavored Equinox.

		The stylistically varied work, which ranged from aggressive FLA-derived techno to Delerium-style ambience, seemed to mark Noise Unit as the moniker of choice for material that didn't quite fit the mould for any other Leeb/Fulber project.

		Though they probably aren't as personally steeped in psychedelics as their music, the members of Bethany Curve seem to have spent a lot of time listening to the finer points of "space rock." This record won't make you dance, but parts of it might just float you across the room.
		Their goal is obviously to overload the listener with gloomy and shivering, yet strangely enlivening noise.

	What's the physical meaning of voltage noise unit V/(Hz)^1/2
		If all you have is a true RMS meter you can put a simple RC low pass filter after the series capacitor and get a crude measurement of the RMS voltage over the bandwidth which is actually 1.57 times wider than the -3 dB frequency of the filter.
		A loose definition of noise is the output power, or power spectral density (power in a given bandwidth) with no input signal.
		The advice on measurement is good, but don't forget to have a calibrated resistor or metal film resistor for the measurement so the noise is ideal thermal noise i.e.

	ANC-4 Antenna Noise Canceller (Site not responding. Last check: 2007-10-30)
		The ANC-4 unit connects right to the antenna connector of the receiver or transceiver to cancel locally generated noise before it gets into the receiver and affects the receiver AGC circuits.
		This scheme is particularly effective at reducing local power line noise or other locally generated noise types.Front panel controls allow adjustment of both the phase and magnitude of the local interference, providing extremely deep cancellation of the offending interference.The ANC-4 connects between the main station antenna and the receiver antenna connector.
		Any noise antenna that works, including combinations of horizontal and vertically polarized antennas, is satisfactory.The ANC-4 operates as an active antenna by using the noise antenna and the NOISE GAIN control to amplify the antenna output.

	Noise models (Site not responding. Last check: 2007-10-30)
		Noise in imaging systems is usually either additive or multiplicative.
		White noise is spatially uncorrelated: the noise for each pixel is independent and identically distributed (iid).
		This makes Gaussian noise a worst-case scenario for nonlinear image restoration filters, in the sense that the improvement over linear filters is least for Gaussian noise.

		The noise reduction offered by the optional acoustic attenuation system allows for the HPU to be positioned close to the testing machine, eliminating the need for a separate pump room.
		HPU cooling is achieved either with water, using an oil plate heat exchanger coupled with a thermostatically controlled water flow valve minimizes water consumption, or through use of an optional air-blast cooling unit, which transfers heat directly into the ambient air, eliminating the need for cooling water.

	NOISE UNIT - Voyeur
		Noise Unit has always been a leftfield experiment to what Leeb and his various collaborators have produced over the years, from the grinding industrial angst of his main project Front Line Assembly, to the ethereal/trancey gloss of the more commercially viable Delerium.
		Paranoid is probably the only track that actually sounds like a Noise Unit track, as stacked up samples breed over a killer Leeb bass line – although forgive me for saying that the bass line does sound stunningly similar to the Boards Of Canada track Roygbiv.
		Nothing wrong with that at all, but this is not the best Noise Unit album.
