Although modern headphones have been particularly widely sold and used for listening to stereo recordings since the release of the Walkman, there is subjective debate regarding the nature of their reproduction of stereo sound. Stereo recordings represent the position of horizontal depth cues (stereo separation) via volume differences of the sound in question between the two channels.
When the sounds from two speakers mix, they create the phase difference the brain uses to locate direction. Through most headphones, because the right and left channels do not combine in this manner, the illusion of the phantom centre can be perceived as lost.
Hard panned sounds will also only be heard only in one ear rather than from one side. This latter point is of particular import for earlier stereo recordings which were less sophisticated, sometimes playing vocals through one channel and music through the other.
Binaural recordings use a different microphone technique to encode direction directly as phase, with very little amplitude difference (except above 2 kHz) often using a dummy head, and can produce a surprisingly life-like spatial impression through headphones. Commercial recordings almost always use stereo recording, because historically loudspeaker listening has been more popular than headphone listening.
It is possible to change the spatial effects of stereo sound on headphones to better approximate the presentation of speaker reproduction by using frequency-dependent cross-feed between the channels, or–better still–a Blumlein shuffler (a custom EQ employed to augment the low-frequency content of the difference information in a stereo signal). While cross-feed can reduce the unpleasantness that some listeners find with hard panned stereo in headphones, the use of a dummy head during recording, with artificial pinnae, can allow on playback through headphones, the experience of hearing the performance as though situated in the positron of the dummy head.
Optimal sound is achieved when the dummy head matches the listener’s head, since pinnae vary greatly in size and shape.
Headsets can have an ergonomic benefits over traditional telephone handsets[citation needed]. They allow call center agents to maintain better posture instead of tilting their head sideways to cradle a handset[citation needed].

Now, before you start thinking that I’m full of myself, let me explain what this is really all about.
In a blog post I made, I talked about the need for your site to actually be related to the links that point to it. One example I gave was the coolest guy on the planet search phrase, versus the miserable failure search phrase.
In the past, searching for “miserable failure” brought up a completely unrelated web page. Due to Google’s new algorithm that does away with the “Google bomb” or “link bomb” effect, that is no longer the case.
My post discussed why this doesn’t work anymore.
In one of the comments on that post, Alex Newell suggested that I setup a site and try to get it to rank for the phrase “coolest guy on the planet”, using the site to test various linking strategies and methods, etc.
Thus my the coolest guy on the planet site was born.
What I am attempting to prove is that by following the directions Google gives in its Webmaster Guidelines, you can rank a site for a keyword phrase using 100% “white hat” methods.
In the pages of the site you will see outlined the methods I am using, and the progress I am making in implementing each of the steps from Google’s guidelines.
As of right now, the site is ranked #1 in Google for “coolest guy on the planet”, but I also want to be ranked #1 for “the coolest guy on the planet”, so I’m still working on it.

Without studying calculus, the scholar will not get the opportunity to pursue engineering or other branch of knowledge. The calculus tutor with his fascination for the topic, will take wonderful effort to coach the student.
The calculus tutor can give ample time and attention to elevate the scholar’s knowledge of calculus. The vast amount of assignments given from school will be difficult. The child would not be fond to do it. The teacher will persuade and tutor the student in completing his housework regularly.
Whether it is concept of limits or continuity, or any concept the child finds difficult will become easy through continuous learning. With frequent learning, the student would improve the child’s understanding in calculus. The tutor is clever to make difficult things simple.
The tutor will by discussing with the scholar realize to what level the child is able to understand calculus. Now the desire of the teacher will be to pick up this level. The coach will coach to take the child to the higher level in calculus.
The tutor should be a very demanding person. The tutor should have listed tutorials for quite a few students by face to face interaction. Hence care takers can contact the tutor for their scholar and request coming to their house as required. The scholar is now very involved in grasping mathematics. By having apparent comprehension of trigonometry, the scholar is to will like maths more and more.
The calculus tutor is very essential to the student doing tremendously well in his exams. The teacher is a friend during tests. The child is very loving of the teacher. The child acknowledges the teacher’s guidance prior to examinations and when seemingly simple sums seem difficult to the scholar.
