   Extractions: Interior noise in a vehicle, either arising from the heating and cooling systems or from the contact between the tire and the road, can be distracting to drivers. This project focuses on reducing the interior noise in a vehicle by alleviating noise generation at the source, and by cancelling any residual generated noise. For airborne noise from heating and cooling systems, investigators are studying multiple-fan systems and speed/phase control of each fan as a potential way to achieve noise control. For structure-borne noise, investigators are reviewing the effectiveness of various approaches to develop road noise control systems. Investigators

   Demonstration Project. Category Environmental Monitoring. Demonstration Project Evaluation of Chamber Acoustic noise environment. Project Lead Theodore Foley.

   Extractions: Noise is a very important part of the environment which can effect communications, general well being, and in the extreme case can result in loss of hearing. Measuring and controlling noise levels becomes more important when you cannot get out of your environment to go somewhere different or quiet. The results of this study will be used to recommend procedures for protecting crewmembers from excessive noise and for modifying equipment to be more quiet. This project consists of 5 interdependent components: Measuring the total noise each crewmember is exposed to on a typical day. Determining sources and measuring the levels of noise emitting equipment. Mapping noise levels within the chamber. Evaluating and redirecting the noise measurements as necessary. Hardware: Sound level and frequency spectrum meters Web Accessibility and Policy Notices Curator: Victor M. Escobedo Jr.

    Extractions: Subject: Noise Environment Sub-Committee - Initial Proposal Author: Motorola Date August 11, 1999 In response to FCC requests, the TAC formed three sub-committees covering various topics impacting radio spectrum policy. These topics were Software Radio, Ultra Wideband Radio and the Noise Environment. The charter of the Noise Environment sub-committee was defined as follows. Noise Environment Sub-Committee Charter Assess and report to the Commission the current state of knowledge on electromagnetic noise levels and the effects of such noise on the reliability of existing and future communications systems. Identify, if possible, man made causes of electromagnetic noise that have or are likely to have harmful effects on wireless communications. Identify issues or causes of man made electromagnetic noise that justify FCC attention or action. Determine what types (if any) of electromagnetic noise create significant concerns and suggest technical approaches for obtaining sufficient information on the subject Our approach to addressing this charter was to first define the scope of this effort. We felt that potential noise from RF communication devices (Cell phones, two-way radios, microwave equipment, etc), other types of devices (e.g. computers, cars, power lines, industrial equipment) and natural phenomena (atmospheric noise, sun spots) should be included as possible sources.

On my shunt-fed tower, in daytime, the S-meter on my Mark V (which is extremely generous below S9) reads a steady S9 +10 with the radio in USB mode and the standard filters in use. Switching to a K9AY loop 350 feet away from the tower (with a 20 dB preamp) drops the level of the noise to S7-8. I have listened to the noise in both USB and AM positions, and do not hear the 60 Hz AC arc sound that I have gotten used to in my efforts to track down power-line noise.

I've done some more observations, including one just now using the waterfall and spectrogram displays in my DX4WIN PSK31 module, but without the sound card (i.e., live, not recorded) to eliminate any extraneous hum or other variables that the card might introduce. The 120 Hz line is VERY visible, and I can see harmonics all the way out to at least the 10th harmonic of 60 Hz (the display only goes down to 100 Hz). When I disconnect the antenna, all of this (along with the white noise across the passband) goes away, so I don't believe any of it is internal to the radio. Another aspect that I find interesting is that this noise level does not extend very far up the spectrum. Given that the antennas differ for each band, on 80 meters the level is only S5-7, with much higher variability (spikes to S8), and the highest level to the south. On 20, the level is S1. On all three bands, however, the 120 Hz line remains clearly visible, and on 80 there is also a pronounced 240 hz line, particularly when the array is looking south. It may be only coincidence that I have a 500 kv line in that direction.

    Extractions: NPC Home FOREWORD The Congress included among the requirements of the Noise Control Act of 1972 a directive that the Administrator of the Environmental Protection Agency "...develop and publish criteria with respect to noise..." and then "publish information on the levels of environmental noise the attainment and maintenance of which in defined areas under various conditions are requisite to protect the public health and welfare with an adequate margin of safety." Not all of the scientific work that is required for basing such levels of environmental noise on precise objective factors has been completed. Some investigations are currently underway, and the need for others has been identified. These involve both special studies on various aspects of effects of noise on humans and the accumulation of additional epidemiological data. In some cases, a considerable period of time must elapse before the results will be meaningful, due to the long-term nature of the investigations involved. Nonetheless, there is information available from which extrapolations are possible and about which reasoned judgments can be made.

    Extractions: We have already defined sound as any pressure variation that can be detected by the human ear. The number of pressure variations per second is called the frequency of sound, and is measured in hertz (Hz). The normal hearing for a healthy young person ranges from approximately 20 Hz to 20000 Hz (20 kHz). In terms of sound pressure levels, audible sound ranges from the threshold of hearing at dB to the threshold of pain at 130 dB and over. Although an increase of 6 dB represents a doubling of the sound pressure, an increase of about 8 10 dB is required before the sound subjectively appears to be significantly louder. Similarly, the smallest perceptible change is about 1 dB. About this Booklet Introduction What is Sound? Types of Noise ...

Some stories are dramatic, most less so, but huge effort and great sums of money are often invested in conflicts involving environmental noise.
