What are Earbuds

With a lot information on the web about headset’s it’s hard to discover the best and generally truthful information. here�s an article from a good blog that i believe as accurate, don’t quote me on it but please read and enjoy
Earbuds are headphones, typically made out of a hard plastic material, that fit inside the ear, just outside of the ear canal. These aren�t the same thing as ear canal headphones, which have a rubber tip and seal within a listener�s ear canal.

Several portable music devices, like mp3s and Personal Digital Assistants (PDAs), come with earbuds when the device is purchased. Earbuds are a less expensive alternative to ear canal headphones or other listening devices. Consumers tend to purchase earbuds for their convenience, as they are easier to carry around than other headphones because of their small size.

This style of headphone also tends to be more inexpensive than other kinds, like ear canal headphones, circumaural headphones that fit outside the ears, or the supra-aural headphones that have pads that are placed on top of the ears, rather than around or inside them. Circumaural headphones are typically used in recording studios and supra-aural headphones can still be purchased at some stores, though these kinds of devices have given way to headphones that fit within the ear.

Because of the design of earbuds, there can be a few drawbacks to owning them as opposed to owning another style of headphone. First, the rigid design of earbuds can sometimes make it difficult for them to fit comfortably inside a listener�s ear. If they�re too large or too small, they can either slip out of the ear or won�t fit inside it at all. Another problem reported by consumers is that because earbuds don�t seal the ear canal, the sound quality is muddled through other ambient noises.

Essentially, most earbuds work the same as other headphones and the set-up is relatively simple. Wires move up from the electronic device that is putting out sound, such as an mp3 player. These wires connect to a voice coil. The coil is attached to a cone, which is flexible and plastic. A magnet is attached to the back of the earbuds. When sound passes up through the wires and to the magnet, the voice coil becomes electromagnetic and moves up and down with the sound. The cone then pushes the sound out through the earbud and into the listener�s ear.

When listening to earbuds or any other type of headphones, physicians recommend to keep the volume at a reasonable level, as research had proven that prolonged exposure to high noise levels can lead to permanent hearing loss. Prolonged listening to loud noises, including music, puts unnecessary stress on the hairs in the cochlea. This causes permanent damage to the hairs and can eventually lead to hearing loss.

How Do Noise Cancelling Headphones Work?

Some of the professional writers on the web are at such a high level that i wonder if any of them have ever written a book? so every now and then i like to focus on these brilliant items and here is one i found fascinating the other day.

Noise cancelling headphones are useful to block out noise in noisy environments like trains, buses, and public places.

The technical theory that is worked out is that this device copies the sound waves from outside and then they make these sound waves go out of phase. It can be also compared to that of swimming upstream. If a river’s downstream current is directly proportionate to your upstream swimming strength, then you stay still.

In this case, the device stays quiet!

There are two models of noise cancelling headphones. Over-the -head headphones are a little larger and less compact but the Earbud headphones are compact and can be carried around in your pocket.

There are two types of headphones designed to reduce the interference of the noise that is created in the background. They are the passive noise canceling headphones and the active noise cancelling headphones. Passive noise cancelling headphones work on the theory of muffling the external noise or sound to lessen the interference with music or recorded speech.

Active noise cancelling headphones on the other hand, electronically decrease the external sound and produce a quiet and calm listening environment.

Passive headphones essentially utilize the muffling characteristics that are provided by circum- aural headphones. It is designed like a cup with the rim surrounding the ear. The rim constitutes of high- density foam and sound dampening material. It is soft and doesn’t hurt the ears and it creates an acoustic seal that has the capacity to block 20 decibels of noise.

Active noise cancelling headphones are a more advanced version and have the potential to reduce 20 decibels more noise reduction than the passive model. It uses the phase cancelling technology in its working. This is the main key feature of this model. It works by using a microphone to pick out the external noise which the circum- aural cushions are unable to prevent or block out.

The frequency and the intensity of the external noise are analyzed by the phase canceling circuit and it generates a mirror image of the noise. The noise created is 180 degrees out of phase.

The speaker of the headphones plays the anti-noise along with the music or recorded speech. The artificially generated anti-noise is exactly the opposite of the external noise that has entered the device and so when the two noises meet they cancel out each other. The end result is that the volume of the external noise becomes extinct and the audio you are listening to becomes very clear and audible.
