Analog programmable hearing aids and digital programmable hearing aids are two types of programmable hearing aids. Digital programmable hearing aids are the most popular choice for people seeking a quality hearing aid.

Analog programmable hearing aids are the cheaper type of programmable hearing aids. While analog programmable hearing aids offer a level of customization that that traditional analog hearing aids do not offer, they do not use digital technology.

Programmable hearing aids allow the audiologist to customize the settings of the hearing aid to match the common hearing environments of the individual. The audiologist or hearing professional considers the person's type of hearing loss, tolerance of loud noises, and lifestyle when programming the settings of the hearing aids.

The hearing aid user needs to adjust the settings of analog programmable hearing aids. While the programmable analog hearing aids may have settings for different listening environments, the hearing aid does not automatically adjust to the current levels like a digital programmable hearing aid does.

In addition to automatically adjusting to the hearing levels of the current environment, digital hearing aids offer options that are not available on analog hearing aids. One such option is telecoil technology which allows the hearing aid user to use the telephone and electronic devices more comfortably.

With the use of digital technology, sounds can be evaluated by the hearing aid and noise can be filtered out before the sound is amplified. Traditional hearing aids can only amplify all sounds equally.

Digital hearing aids enhance speech as well as reduce background noise. This makes conversation in groups and noisy environments much easier for the hearing aid user. Hearing aid users often consider digital hearing aids to offer more comfortable listening in many situations.

Digital hearing aids can be smaller models than analog hearing aids. Even the small hearing aid models like the completely-in-canal (CIC) models can be digital.

The main disadvantage of digital programmable hearing aids is the cost. Though most hearing aid users purchase digital hearing aids and some hearing aid companies have stopped making analog hearing aids, some hearing aid users prefer analog hearing aids due to the prices of digital hearing aids.

Sudden hearing loss is significant hearing loss that occurs within three days of the onset. Many aspects of sudden hearing loss are still a mystery. The inability to pinpoint the exact cause of many cases of sudden hearing loss may have negatively affected the development of an effective treatment.

Causes of sudden hearing loss may be traumatic injury, immune disease, and the impairment of circulation which decreases blood flow to the inner ear. Sudden hearing loss after viral infection has been evident in some cases. There are several viruses that have been implicated as a threat to hearing.

Mumps and German measles, also called rubella, are often considered potential causes of sudden hearing loss. Some experts believe that the measles-mumps-rubella vaccine is responsible for some cases of sudden hearing loss, though this is considered very rare.

Herpes viruses have been implicated in cases of hearing loss after viral infection. Other viral infections that have been linked to some cases of sudden hearing loss include the human immunodeficiency virus (HIV), cytomegalovirus (CMV), Lassa fever, and wild-type measles.

Researchers have been unable to replicate sudden hearing loss after viral infection in the laboratory. Therefore, the link between viral infections and sudden hearing loss has not been scientifically proven. Scientists have been unable to confirm the relationship between viral infections and sudden hearing loss.

Very few people who acquire these viral infections will develop sudden hearing loss. Some bacterial infections such as syphilis, meningococcal meningitis, and mycoplasma bacteria can also cause sudden hearing loss.

Inflammation of the cochlea and abnormal changes in the membranous labyrinth of the inner ear due to the infection is believed by some experts to be the cause of sudden hearing loss from infection. These causes have not been scientifically proven.

There are many cases in which the cause of the sudden hearing loss is not identified. The hearing loss may be called idiopathic hearing loss or idiopathic sudden hearing loss if the cause of the sudden hearing loss cannot be determined. Often, sudden hearing loss improves without treatment. In about fifty percent of cases, the hearing loss is recovered mysteriously without treatment which is known as spontaneous recovery.

In the United States, there are about four thousand cases of sudden hearing loss every year. The people most commonly affected are between the ages of fifty and sixty. There is no universally accepted treatment for sudden hearing loss.

Allan has a hearing aid website that discuss about hearing loss reasons and he discuss the degrees of hearing loss on this website. During his quest, he setup this website - wanting to help others find out more about hearing aids.

Analog programmable hearing aids contain a microchip that allows the audiologist or hearing professional to program the settings for different listening environments. The hearing aid may have been programmed for special situations such as a noisy work environment or a quiet home environment.

Audiologists use a computer to personalize the settings for the user who can then adjust the hearing aid settings by remote control or pushing a button. Digital hearing aids automatically adjust unlike analog programmable hearing aids.

Why would someone want an analog programmable hearing aid instead of a digital hearing aid? Analog technology is generally cheaper than digital. Cost is a significant factor in many people's hearing aid decision.

Analog programmable hearing aids have many of the same features as digital hearing aids. The life of an analog programmable hearing aid may be shorter than a digital hearing aid. When programming the hearing aid, the audiologist will consider the type of hearing loss and the person's tolerance for loud noises.

An analog programmable hearing aid costs more than a regular analog hearing aid that cannot be programmed. Many hearing aid manufacturers no longer make analog or analog programmable hearing aids. This may be due to the popularity of digital hearing aids and their features.

In addition to the differences in features such as self-adjustment and cost, analog programmable hearing aids and digital hearing aids process sound differently. Analog programmable hearing aids convert sounds into electrical signals before the sounds are amplified.

With digital hearing aids, sounds are converted to binary code, the language of computers, before being amplified. Digital hearing aids are usually programmable.

Analog programmable hearing aids are available as behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), and completely-in-canal (CIC) hearing aids. A hearing aid user may receive recommendations from the audiologist about which type of hearing aid would best suit the hearing aid user's needs.

Price should not be the exclusive reason for choosing a particular hearing aid. People who would want digital hearing aids but cannot afford them may want to seek financial assistance from a government agency for people with disabilities or a non-profit organization like Audient Alliance.
