Binaural Beats – The History of Binaural Audio

by

Eric Shelton

A current area of interest for neurophysiologists who specialize in the investigation of hearing, is the phenomenon of binaural beats. Discovered by Heinrich Wilhelm Dove in 1839, these low-frequency pulses are said to originate in the brain stem and have been connected with one s ability to locate the directions from which exterior sounds are generated. However, more recent advances in technology have given rise to other claims about their use.

Dove discovered that when two slightly different tones are introduced at once to the brain (via headphones), the brain would begin to produce an illusionary auditory pulse that exists exclusively within the auditory system. This discovery led to a number of positive implications with regard to hearing research, but it also led to a bit of controversy regarding which areas of the brain were actually affected and how those effects manifest themselves.

Recent research by Yale University, has led to an expansion of the idea that binaural beat effects in the human brain include the activation of a multitude of other cognitive functions located at other brain sites. In fact, it is now theorized that the pulses include visual or a mixture of both aural and visual stimuli. The implications of this discovery are far-reaching.

A practical application of binaural beats can be exemplified in inventor Ian Sommerville s conception, and the dream machine. This rotating metal cylinder from which a light is suspended has slits cut into its sides. The precise rotation of the cylinder causes light to pulse from between forty-five and seventy-eight revolutions per sixty seconds to correspond with the natural creation of electric oscillations already emitted by the human brain when it is at rest. As a result, this device has been used for various forms of relaxation therapy.

Robert A. Monroe, founder of the Monroe Institute, a research organization that explores human consciousness, developed another

that has expanded into consumerism. Monroe produced an entire series of CD s under the moniker, Hemi Synch. This specifically aural version of the dream machine s similar relaxing effect is currently being marketed as a meditation tool and is reported to place participants into a dreamlike state that encourages lucid dreaming.

Considered by some skeptics to be the equivalent of consumer snake-oil schemes, the discovery of binaural beats has had a wide scientific acceptance as an actual phenomenon. Those in doubt suggest that rather than produce specific effects such as lucid dreaming; the pulses instead merely mechanically produce a state of hypnosis or suggestibility that emulates deep, restorative sleep.

An open source software called, Gnaural is available for

download on the internet

to enable enthusiasts and skeptics alike to try the technology to arrive at their own conclusions about the effects of binaural beats. The software allows users to use headphones to experience the tonal pulses within the confines of their own homes. The caution is added that it is not recommended that users listen to binaural beats while driving or operating heavy machinery.

Pallet Jack Scales, Why Industries Need Them

by

Some machines assists one in doing heavy work, other assist in getting things done at a more fast rate, while the outstanding ones accomplish both. Whenever such a product is brought into the market, there is always a euphoric rush to get hold of it. Whether this is a misdoing or the right action is subject to discussion. However, a pallet jack scale is one such product which does both. So, what is a pallet jack scale?

A pallet jack scale is described as a weighing gadget that is used for standard measurement of wooden and plastic pallets. They are the standard storage shelves which, manufacturing entities design in specific shapes and sizes to accommodate forklifts. There are various types of pallet truck scales including the manual trucks and the battery operated trucks. Nevertheless, both facilitate weighing of heavy objects when they are being lifted from one point to another with the help of a pallet jack. They not only save time and effort but are also known to return their investment within much shorter duration.

It is important to point out that many manufacturers have emerged in the recent past and as such there are multiple pallet jack scales in the market. Users can select from this available options. Reputation and quality should therefore precede the selection decision that an individual makes. Such can be obtained from the numerous client reviews in related blogs. Previous product users are often in a better position to give reviews of the functional ability of products. However,one may ask, why all the praises about pallet jack scale?

Well, in the modern times, machines that can multi-task are no doubt much more preferable as compared to their single use counterparts. Such machines can do multiple tasks at the same time and hence help one save on time. Weighing while moving makes pallet jack scale fit into this unique category of equipment. It saves the time that would have been used on weighing and then lifting by combining them into a single process package. Both processes are demanding both in terms of resources and time taken to accomplish them. Consequently, bringing them together will increase production and also lower cost of production.

It is important to mention that the accuracy as well as reliability of scales has been largely increased by the emergence of digital scales. The ease of measurement that digital scales offer has largely improved functional ability of the machines. By bringing together the pallet truck and the digital scale, a reliable and increasingly useful machine is now in existence. Nonetheless, selection of the right pallet jack scale requires some level of caution, more especially considering the various movable parts that make up the machine.

Multiple factors should be considered including quality of the machine, readings accuracy, as well as the overall reliability of the machine. You must ask, what would happen if one of the components has a problem. Performance and durability should always be atop the selection process. Investing a little extra time in searching for the appropriate machine will do more good than having to buy a machine that will need up wasting a lot of the organization s man hours, let alone the expenses incurred in maintenance and repair of the machine. A highly reliable pallet jack scale is therefore the most appropriate option.

In general, it is important to mention that while a pallet jack scale is a very useful machine in saving on production overheads, poor choices can compromise the overall goal of the investment. So, take caution and be careful when making selection decisions. A second invested in assessing available options, is a second saved.

Pallet Scale

Scales are used for taking various measurements, whether it is weight, volume or mass. Now-a-days digital scales are used largely. Scales give the measurement which is required while disposing anything or to accommodate anything. Click here for
