What Are the Best Noise Cancelling Headphones?

!9#: What Are the Best Noise Cancelling Headphones?

By now you've probably heard about them. Either through a friend or reviewer, you've probably heard something about the greatness of noise cancellation in headphones. But what does this really mean? And which of these headphones is really the best? In this article we will explore what are considered to the best noise cancelling headphones on the market right now. We will also look at what the technology really is and how it works.

What Are Noise Cancelling Headphones?

These headphones are derived from a special technology that allows you to tune out the unnecessary noise in your headset speakers. But, of course, you don't actually do the work - the headphones do it for you. To break the process down for you, noise cancellation is created by a few steps that all take place in or around the headset speakers.

First, there is a microphone that is placed near the ear that produces a sound called an antinoise wave. The wave has an opposite polarity of the sound wave that is arriving at the microphone from the actual music source. When they meet up (or collide) they cancel each other out. This effect is called phase cancellation. Once phase cancellation occurs, a new sound wave is created called destructive interference. Destructive interference works to eliminate all of the "messy" sounds that come from the music source so that when the original sound wave comes to the speakers, only the clean aspects of the sound will be heard - very complex and very cool!

Are There Benefits to Noise Cancellation?

There are many benefits to finding the best noise cancelling headphones out there. For one, you are able to benefit from a very detailed process meant specifically to increase the quality of your listening experience. Many reviewers say this is great because the result is so clean and crisp that you don't have to turn up the volume on your musical device to hear all of the intricacies of a composition, which is not only good news for those who love to hear the subtleties of music, but also for those who feared going deaf in the near future from turning the volume up so high.

Another reason to seek and find the best noise cancelling headphones available is because they are able to block out not only what you don't want to hear in the song, but also what you don't want to hear around you. Because the technology involved in the headphones helps to diffuse noises near the speaker, it also helps to diffuse noises around you, like the low rumbling of a jet engine as it revs up. This gives you two benefits for the price of one, which is always a major selling point.

What Are the Best Noise Cancelling Headphones?

Bose Quiet Comfort 2 - There are actually two different models from Bose that are very popular, thus there is a debate as to which are the best noise cancelling headphones between the two. However, since more people tend to like the price tag of the Quiet Comfort 2 (as opposed to Quiet Comfort 3), I thought I would look out for the more spend-thrifty consumer in this situation. These headphones are a great choice and are very popular with airlines because they can diffuse the sounds of airplanes and people during a flight; they are said to be so good that they can even block out sounds when no music is turned on. Also, they give you a very crisp, clean musical experience, which is great for travel or just sitting in your home. It is for these reasons that reviewers and customers alike highly recommend them for your listening pleasure.

JVC HA-NC250 - These make the list as one of the best noise cancelling headphones, but not for their price (though they are not as costly as some out there). The main reason people love these headsets is because they have extremely comfortable leatherette ear cups that are oblong instead of circular so that they can actually fit the shape of the ear; this means there won't be as much pressure and ear sweating - nice perk! To brag a little bit more about the fit, most customers tend to like the idea that the arms are adjustable and the cups swivel forward and backward.

Now, let's get to the sound quality. They are said to block out high-frequency sounds very well and produce a clean, open sound as advertised. The bass is tight, but not overwhelming, which is good. And the overall, the audio response is even. The headphones come with a nice carrying case, an airplane adapter, and a removable cable. All things considered, it seems that they are a good bargain for the price.

Sennheiser PXC-300 - These made the best noise cancelling headphones list because of their state-of-the-art NoiseGard Advance active noise cancellation technology that guarantees a disturbance-free musical experience even in the most distracting environments. They are said to reduce unwanted noise in (and around) the speakers up to 80 percent. They even say that these headphones don't succumb to the annoyances of that weird cell phone interference (you know that weird noise that cell phones create making your computers and alarm clocks go crazy). They are easy to carry, coming with a soft, protective case, and they have a folding mechanism that lets them easily glide them into the case. Possibly the best aspect of the headset, however, is the 2-year warranty that accompanies it.

There are a few other brands and models that could have been considered the best noise cancelling headphones; however, these are most popular among a larger number of reviewers. Before you run out and purchase one of each pair though, I recommend you get out there and try them on for size. You might find that none of them work for you. Then you'll be mad at me for having you run out to buy what I think are the best noise cancelling headphones, when in actually, only you can determine which are the best ones for you.

The Body's Crystal Matrix - Part Two

!9# The Body's Crystal Matrix - Part Two

[if ]
[endif]

The human body is a sophisticated, multi-faceted antenna system comprised of a crystalline matrix that is constantly transmitting and receiving (transceiving) all manner of informed energies. The matrix is mainly comprised of two special types of crystals known as piezo and liquid crystals. In Part One, we covered the function of piezo crystals and how they convert electrical energy into mechanical energy and vice versa, creating piezoelectricity. In Part Two, we will investigate the roll of liquid crystals in the body's matrix.

Like piezo crystals, liquid crystals also detect mechanical stress and change shape. These are the same sort of crystals found in many flat-screen computer monitors and televisions. The goo that forms at the bottom of a soap dish contains liquid crystals as well.

According to Professor Peter J. Collings, who wrote the de facto standard book on this topic titled Liquid Crystals: Nature's Delicate Phase of Matter, liquid crystals have become a major source of investigation since the 1960s. They are of particular interest to biologists because liquid crystals can also detect minute changes in electromagnetic radiation levels.

Cell membranes are liquid crystal structures. The configuration they form helps segregate different parts of the cell from one another. Investigation of the cell membrane function may lead to a greater understanding of why some anesthetics work so well, even at low dosage. A better understanding of how liquid crystals function in the body may also help treat diseases such as Multiple Sclerosis, Sickle Cell Anemia and even Cancer. Because the arrangement of DNA in chromosomes also possesses a liquid crystal structure, geneticists are investigating these unique components as well.

Collings also suggests that "the ability of biological organisms to form fluid structures of some rigidity in an aqueous environment is central to the existence of life on this planet." James L. Oschman, who authored Energy Medicine: The Scientific Basis, echoes this sentiment by stating that "crystalline arrangements are the rule, not the exception, in living systems." He goes on to suggest that energy and body workers who use quartz, shells and stones, which are also crystalline materials, create resonant interactions with the liquid crystal structures found in tissue. He states that, "Crystalline components of the living matrix act as a coherent molecular antenna, radiating and receiving signals."

The way to tune this antenna is through the repetition of such practices as yoga, martial arts or even playing an instrument. These disciplines also involve entrainment, which is mindfulness of breathing and heartbeat rhythms that bring the body and brainwave activity into a synchronous, harmonious state. Entrainment of the crystalline matrix in this way brings the entire being into a state of coherence. In other words, the whole being becomes one big, resonant antenna.

Coherent states are an important subject of study in quantum physics as well. Much attention is currently being focused on the properties and characteristics of a Bose-Einstein condensate. Instead of the molecules in a substance acting as individual entities, when they are cooled to the point of reaching a condensate level, they suddenly act as one unit. Point-like particles take on a wave nature, overlapping and interacting in such a way that they loose their individual identities.

Oschman goes a step further to say that the process of entrainment is aided by phonons, which are a unit of measure of the sonic vibrational energy occurring in a crystal lattice structure. He defines them specifically as, "electromechanical waves in a piezoelectric medium." Phonons couple the natural sounds of the body such as those made by the heart and lungs, to the crystalline lattice structures of the body.

Phonons are to sound waves what photons are to light waves. Phonons are considered quantum harmonic oscillators, meaning that they are spaced in regular, discreet intervals. Mathematically, they obey the same statistical relationships as found in quantum coherent systems of light such as a laser.

Most beginning meditation practices focus on breathing and the slowing of the heart's rate. Through sound, this entrains the body and brain activity to come into a synchronous state and begins to properly align the body's antenna system to transceive higher frequencies by inducing a coherent state.

From our bones to our cells, the crystal matrix of the body turns it into one large antenna for the transmission and reception of many types of informed energies including those that are filtered through the subtle energy bodies. Traditional Ancient Chinese medicine asserts that this flow between the physical body and the subtle energy bodies occurs through the exit and entry points along the meridian system. Positioning the body in certain ritualistic postures, such as those found in Tai Chi and yoga, aid in transceiving these informed energies.

Audio Equipment for in Car Entertainment

!9# Audio Equipment for in Car Entertainment

[if ]

The best audio equipment for in car entertainment for the driver and passenger is where it makes a long journey much more enjoyable by creating the illusion of time passing much more quickly. This can either be listening to the radio or enjoying an album by some very talented artist. The problem with most radios however is that they tell you the time at regular intervals which can be problematic in terms of making time apparently passing much more quickly.

Sometimes the driver would only like to concentrate on the road whilst the passenger do the opposite and listen to music as loud as possible. the best solution for such situations is to have noise cancelling headphones that are also very well insulated sound-wise. This way the driver will not hear any leaked noise and the passenger will not hear any background noise.

To get premium car audio systems you cannot go wrong with Alpine or Panasonic. These two brands produces high quality electronic equipment across the board. The days of radio channels as the only source of in car entertainment is long gone. Now you have touchscreen video displays and Bluetooth wifi connections to you iPhone, which allows you to play any stored music on your phone very quickly and efficiently.

Audio equipment for in car entertainment is adaptable

When setting up car audio systems you can use your imagination as opposed to limiting yourself to packages that the shops have. For example you can set up your own custom made speakers in the positions that you want to get a surround sound experience. The subwoofer setup alone can let your imagination run wild with possibilities. The only difficulty most people might have is the technical knowledge required to set up car audio equipment. Buying car entertainment packages is a lot more simple for most, packages such as Bose media systems are a great buy.

Acoustic noise cancellation headphones

In recent years there have been many advances in headphone and hands free technologies which relate to you automobile. Acoustic noise cancellation headphones work by destructing all incoming sound waves by applying the opposite sound wave to them. the concept is actually very solid but in practice it does not block out 100% of background sound. Most manufactures display the actual amount of sound blocked out which is typically between 50% and 70%. However I have very little doubt that in the next decade the top manufactures will find a way to further increase the quality of noise cancelling headphones.

The interfaces of audio equipment for cars is getting better every year. The best current interface is touchscreen monitors because they made both for the driver and passenger with user friendliness in mind. The only drawback of this interface is that it requires a relatively large amount of space on the car dashboard to be effective, but if correctly positioned then it can be done with little compromise of other dashboard interfaces such as temperature control.

High end audio equipment for sale

To get the best sales and bargains on audio systems the electrical equipment in general visit online retail outlets such as Amazon and eBay. They consistently have the widest choice of products at the lowest prices. Panasonic headphones, Bose media systems and personalized amplification systems are just some of the range of car entertainment equipment there is to buy.
