How do earphones help in hearing better?

Question

No silly aswers please.

HELLO ! I'm talking about EARphones, not HEADphones.

Answer 1

Nice Q. Earphone is really important for my dad. He has a big trouble in hearing ability. So I have to shout if he does not use the aid.

I think a earphone receives the sound waves from nearby and amplifies it.

As far I know, an earphone is a device used to help hard-of-hearing people hear sounds better. In the past, a funnel-like amplification cone, called an "ear trumpet" or "ear horn", was used. Also sometimes used was a desk with a built-in amplifier into which a microphone and earphones could be plugged; these worked better than passive ear trumpets but were not portable.

Now, however, the most common style is a small electronic device that fits into the wearer's ear. The first variety of this device had a rectangular battery pack connected by a thin wire, intended to be held in a pocket. Such "body aids," though much more portable than the desk type, still suffered significant disadvantages because the microphone was not near the user's head, such as clothing noise and being located below the mouth of a person with whom the user was conversing.

During the mid- to late 20th century, hearing aids that were carried in pockets were replaced by a more inconspicuous sort of model in which small zinc-air batteries were placed in the inserted unit itself.

The inside mechanisms of hearing aids vary among devices, even if they are the same style. Three types of circuitry, or electronics, are used:

* Analog/Adjustable: The hearing professional (Audiometrist,Hearing Instrument Specialist, Hearing Aid Dispenser orAudiologist) determines the volume and other specifications you need in your hearing aid, and then a laboratory builds the aid to meet those specifications. The hearing professional retains some flexibility to make adjustments. This type of circuitry is generally the least expensive.

* Analog/Programmable: The hearing professional uses a computer to program your hearing aid. The circuitry of analog/programmable hearing aids will accommodate more than one program or setting. If the aid is equipped with a remote control device, the wearer can change the program to accommodate a given listening environment. Analog/programmable circuitry can be used in all types of hearing aids.

* Digital/Programmable: The hearing professional programs the hearing aid with a computer and can adjust the sound quality and response time on an individual basis. Digital hearing aids use a microphone, receiver, battery, and computer chip. Digital circuitry provides the most flexibility for the hearing professional to make adjustments for the hearing aid. Digital circuitry can be used in all types of hearing aids and is typically the most expensive. However, digital hearing aids can be specially programmed with multiple programs for quiet situations, background noise reduction, music listening and directionality. Many also have more powerful feedback-reduction and/or cancellation technology.

Answer 2

They amplify sound...the problem is all sounds are amplified, not just a person's voice or some other sound the listener wants to hear.

A noisy room or busy intersection make it hard for the earphone-wearer to focus on any particular sound.

Answer 3

Well In many cases the nerves connected to the ear on the backside of the head have become less sensitive and needs to be made sensitive with outside help which the ear phones do.
Atleast I have seen many children who were thought to be dumb were not really dumb but because their hearing had been impaired they appeared to be dumb and after course correction they are back to normal children but after great efforts.
