Noise communication affects

In accordance with the Invention, therefore, the chamber has at Its front end a section of reduced cross-sectional area. Weight, size and cost are reduced without seriously affecting the efficiency of noise reduction. The silencer may be built as an attachment or, preferably, the rear porfion of the chamber may be built around the barrel of the firearm, with communicating holes through the barrel. The heat absorbing material may be metal screen, which may take the form of apertured discs, stacked one upon another and preferably held In compression. Plating the screen with some metal such as tin before punching the discs will increase the stability of performance. ... 

In conclusion, the EDA technology effectively removes lead with a high level of treatment efficiency and it does not destroy or degrade the physical properties of the affected media. It also presents minimal short-term risks to workers and nearby community, including noise and exposure to airborne contaminants. 

Communication barriers often also called noise or static can complicate the communication process. While unavoidable, both the sender and receiver must work to minimize them. Interpersonal communication barriers can arise within the realm of either the sender or receiver. If an individual holds a bias against the topic under discussion, anything said in the conversation can affect perception. 

The set of noise belong to the background noise do not show an important affectation to the throughput on the communication network when the load is connected at the Tx side. The phenomenon is explained by the low power density of this kind of noises in the range of frequencies used by PLC, see Figure 15. 

Noises on pwwerline communication channels such as coloured noise, narrow band noise, periodic impulsive noise and asynchronous impulsive noise affect PLC network throughpnit. However, these noises can be successfully controlled by band-p>ass and band-stop filters installed on strategic PLC network connection points. 

Real-world communication channels adversely affect the received signal due to noise and attenuation. A communication receiver designed to operate in the presence of noise is similar to the designs shown but with an additional bandpass filter inserted immediately before the receiver input (see Fig. 12.28). The filter removes noise and interference energy outside the passband. 

Noise is commonly defined as any unwanted sound. Noise literally surrounds us every day and is with us just about everywhere we go however, the noise we are concerned with here is that produced by industrial processes. Excessive amounts of noise in the work environment (and outside of it) cause many problems for workers, including increased stress levels, interference with communication, disrupted concentration, and, most importantly, varying degrees of hearing loss. Exposure to high noise levels also adversely affects job performance and increases accident rates. 

Although not listed by the NEC, another important purpose of grounding is to reduce electrical noise that can interfere with electronic equipment. Poor grounding practices could affect communication and automation equipment. 

Environmental noise is not usually a concern. Most platforms are far enough from the shore that the noise that is generated will not affect the community, and general community noise will not affect the offshore workers. 

All of the reports, papers, and oral presentations constitute communication. But, in an information sense, such forms of exchange are filtered and subject to noise. The reports only contain a fraction of what is in the original log, and papers contain a personal interpretive flavor. Oral presentations may be less connected to fact, are ephemeral, and may be affected by the fluency of the speaker and the attention of the listener. A return to the original notebooks usually finds that they are difficult to follow because of arcane notations, or incompleteness. Even the flow of the research is difficult to track since many activities are usually intertwined. 

An inexpensive LI GPS module is connected to the wireless sensor module through a serial communication. The electric current is about 50 mA (3 V) which is highest among the electric components of the prototype. In the prototype, a small patch antenna is employed, which is generally never used for the precise displacement determination because such a small patch antenna has weak directivity and then the data is largely affected by the multipath noises. This noise contamination makes it difficult to resolve the integer ambiguities.
