Added for You - Environmental Noise -- How it Hurts Us, and How We Can Silence It
Are you interested in trying your hand at futures trading? Futures trading involves the trading of commodities for a future date. If you are interested in futures trading, you may be wondering whether you should use the assistance of a commodity trading broker or do your own commodities trading online. While a large number of futures traders choose online commodities trading, it doesn’t necessarily mean that it is right for you.Online commodities trading is when a trader, just like you, decides that they are able to handle their own trading and portfolio. Often times, a commodities broker is only contacted to help setup an online account, after that online commodities trading traders are often on their own. For that reason, only those who know w
Most people follow their uplines so-called advice and have absolutely nothing to show for it. Chances are great that you are one of them! Sure they may give you a temporary high by repeating some motivational quote he read in some success book, but how motivated are you REALLY when you have no money to show for it?You probably feel that there is something wrong with you and that you are not trying hard enough to talk to enough prospects. But have you looked at it in another perspective?I know you have listened to all those tapes that your upline shove down your throat, but have you considered that the so called advice they give you is outdated and ineffective? And maybe even actually making you fail?Sure they may make you feel that t
Those involved with the more obvious noise sources such as airports, shooting sports, manufacturing or even musical concerts have long known the detrimental effect of extreme noise levels on long-term hearing. Only recently, however, has environmental noise been thoroughly researched for its affect on our mental and physical health – and the findings may surprise you. But to gain a better understanding, one needs a basic education on what, exactly, noise is.
Noise intensity is measured in decibel units. The decibel scale is logarithmic; each 10-decibel increase represents a tenfold increase in noise intensity. Human perception of loudness also conforms to a logarithmic scale; a 10-decibel increase is perceived as roughly a doubling of loudness. Thus, 30 decibels is 10 times more intense than 20 decibels and sounds twice as loud; 40 decibels is 100 times more intense than 20 and sounds 4 times as loud; 80 decibels is 1 million times more intense than 20 and sounds 64 times as loud. Distance diminishes the effective decibel level reaching the ear. Thus, moderate auto traffic at a distance of 100 ft (30 m) rates about 50 decibels. To a driver with a car window open or a pedestrian on the sidewalk, the same traffic rates about 70 decibels; that is, it sounds 4 times louder. At a distance of 2,000 ft (600 m), the noise of a jet takeoff reaches about 110 decibels—approximately the same as an automobile horn only 3 ft (1 m) away. ?
Subjected to 45 decibels of noise, the average person cannot sleep. At 120 decibels the ear registers pain, but hearing damage begins at a much lower level, about 85 decibels. The duration of the exposure is also important. There is evidence that among young Americans hearing sensitivity is decreasing year by year because of exposure to noise, including excessively amplified music. Apart from hearing loss, such noise can cause lack of sleep, irritability, heartburn, indigestion, ulcers, high blood pressure, and possibly heart disease. One burst of noise, as from a passing truck, is known to alter endocrine, neurological, and cardiovascular functions in many individuals; prolonged or frequent exposure to such noise tends to make the physiological disturbances chronic. In addition, noise-induced s
Part I of this article covered what to avoid when giving a business gift. If you missed it, I suggest you go back and take the time to read it.Now onto Part II: Giving corporate or business gifts can help you stay in touch with prospects and clients. It can also help you show appreciation for someone's business, establish new relationships, mend relationships, obtain referrals and build customer loyalty. Follow the guidelines below to ensure that your business gifts are effective:Good Choices for Corporate Gifts: Gourmet and snack food items that can be shared easily within an office. Cheese, crackers, sausage, chocolate treats, cookies, flavored coffees

I've learned important lessons over my 15 year career as a cleaning and restoration business owner and one of the more important lessons is that trying to learn every little detail about every business function will DRIVE YOU CRAZY! Having said that it's still important to understand key concepts of your business and options, but trying to learn all the details of taxes, the legal system, business structure, etc. will most likely stunt your business growth or add many unnecessary years to becoming extremely successful.Your Advisory StaffAs stated above, there are functions in your business that you need to fully understand; but you can't possibly or even need to understand every little detail. That's what an Advisory Staff is for. Let's

In an ever-expanding corporate environment, the need to have an individual identity is a must to stand out from the crowd and get noticed. There are several ways of making this statement such as brand advertising, promotion campaigns and a personalized logo. However, a very subtle yet effective method used to highlight a person or organization’s individuality is the use of personalized rubber stamps.A personalized rubber stamp allows the users to craft their own design, logo, slogan or signature for the stamp. The engravings in the rubber base are made exactly according to the need of the user, adding to the tailor-made approach. These rubber stamps also make the perfect gift for any occasion.Personalized rubber stamps come in various shapes a

An original equipment manufacturer or OEM is a company that manufactures goods or gadgets, which are utilized in products sold by another company. These companies are usually termed as a Value Added Resellers or VARs. An OEM usually builds to order, on the basis of the designs provided by the VAR. There are various categories of equipment manufacturing suppliers, such as electrical and electronic test equipment, equipment rental and leasing services, separation equipment and filtration equipment, sprayers and spray coating equipment. The equipment also includes automated test equipment, powder compacting equipment, network test equipment, battery testers and fuel cell test equipment, powder coating equipment and de burring equipment.There are laborat
Does this mean we are doomed to a noise-filled life of stress? Fortunately, no. Noise is now recognized as a controllable problem that can be minimized via varied abatement technologies. In the United States the Noise Control Act of 1972 empowered the Environmental Protection Agency to determine the limits of noise required to protect public health and welfare; to set noise emission standards for major sources of noise in the environment, including transportation equipment and facilities, construction equipment, and electrical machinery; and to recommend regulations for controlling aircraft noise and sonic booms. Also in the 1970s, the Occupational Safety and Health Administration began to try to reduce workplace noise. And over the past 30 years, the general public has become increasingly aware of the hazards of environmental noise, and its ability to combat it on an individual and collective level.
One of the most effective environmental noise abatement technologies to be developed is the noise barrier wall, or sound wall. Sound walls are classified as reflective or absorptive. Hard surfaces such as masonry or concrete are considered to be reflective. This means most of the noise is reflected back towards the noise source and beyond. A barrier wall such as the Sound Fighter® LSE 2000 with a porous surface material and sound-dampening content material is said to be absorptive. This means little or no noise is reflected back towards the source or elsewhere.
Sound walls are performance rated in two categories: Sound Transmission Class (STC) and Noise Reduction Coefficient (NRC). The STC determines the amount of noise energy transmitted through the wall material. The NRC determines the amount of energy absorbed by the wall material and the amount of energy reflected back towards the source.
Walls having STC ratings of 30 or more means that less than 0.1 percent of the noise energy is transmitted through the barrier material. Many State Department of Transportation specifications require minimum STC ratings of 24.
NRC measures the amount of sound energy absorbed and measures the amount of sound energy reflected back towards the source. NRC ratings will range
