Analog: "a mechanism in which data is represented by continuously variable physical quantities," Webster. Analog is how the natural world works. We hear and see things in an analog manner. That is to say, in constantly changing, but always connected, waves. Sound appears continuous to our ears. The fact is during average speech there are many stops, starts, gaps and pauses. We only "hear" speech as a continuous sound; regardless of the tiny stops and starts. Additionally, the connected wave of sound that we hear is always changing in strength (volume). Analog hearing aids process sound in a continuous wave. This means quite simply that sound passes through an analog amplifier unbroken. It may get a little bent as it changes from sound waves to electrical waves and back again, but it retains the flow of the original sound wave. Hearing aids remained almost unchanged from 1940 until 1993. Sound quality got better and the parts got smaller, however, the way they worked was unchanged. Analog hearing aids are good at boosting volume but they do very little to help reshape and control sound in a way that provides needed flexibility by the hearing impaired. Analog hearing aids are simple devices. The have simple electronic parts. You could buy the parts to build an analog hearing aid at a Radio Shack. They've been available for decades. Most hearing aid manufactures are no longer making analog hearing aids. For good reason, it costs just as much to make an analog as it does to make an entry level digital. Digital hearing aids work just like computer music. Computerized music, CDs, mp3s, etc all take sound and break it up into little bites (bytes) of information stored as a mathematical equation. The digital computer in the hearing aid can then add or subtract values from those little equations. When the computer puts the numbers back together sound has been altered. Ideally, in a manner that improves your ability to understand speech. There is nothing magic about the term digital. It simply means the sound is handled like any computerized device. It can be very good; It can be very bad. Although digital hearing aids can provide a vastly better hearing experience, they have to be correctly programmed. Analog hearing aids were built at the factory and came "fixed" to the fitter. The fitter could not make many alterations to the output of the instrument. Digitals come as a blank sheet of paper. It's up to the hearing aid fitter to shape the output of the hearing aid. If the digital hearing instrument is well programmed you will have an awesome experience. If it is not, it can be as useless as sticking a rock in your ear.

Analog Hearing Aids work similarly to a microphone hooked up to a speaker. Analog Hearing Aid picks up the sound from outside and amplifies it accordingly and produces an output into a louder volume. Analog hearing aids are programmable and offer multiple listening modes for different environments.

What is hearing aid machine?
Hearing Aid Machine is an electronic instrument or device which is used to determine a person's hearing sensitivity at different frequencies. It produces the better quality of sound. The hearing aid device is used by aiding persons with or compensating for impaired hearing. The hearing aid machine works based on technology. It contains many parts:- · Microphone:- The microphone of hearing aid helps to hear clear and better quality of sound. It converts the sound signal into the electrical signal and sends the signal to the amplifier or processor. The microphone of Hearing aid machine is able to differentiate between speech and background noise. The microphones are two types: directional and omnidirectional. The directional microphones collect mostly sounds in front of the wearer. The wearer can understand clear sound in a noisy environment due to the directional microphone. The omnidirectional microphones collect sounds from all directions. The user can easily understand that where sounds are coming from. So, Microphone is a very useful part for hearing aid. · Processor/Amplifier:- It is the motherboard of the hearing aid. The amplifier receives the electrical signal from the microphone and converts them into digital signals. It is amplified the signal at a suitable level according to users. It is reduced or minimized any noise and feedback. · Receiver:- The receiver is the final component of hearing aid. It receives the digital signal from the processor and converts them into again sound signal because the user can understand only sound waves i.e. audible sound. The receiver is placed in the wearer's inner ear. These all process is done in a fraction of a second. The hearing aid machine is very helpful for hearing loss people. They can hear the sound very clearly and can enjoy the most natural listening experiences.

What dB hearing needs a hearing aid?
Various dB losses require a hearing aid. The question isn't so much what decibel loss requires a hearing aid, but at what point does your hearing interfere with your life enough that a hearing aid would prove beneficial. Because people are different, hearing aid manufacturers intentionally design an array of hearing aids suited to mild (least-affected grade of hearing loss) loss to severe. Additionally, different models of hearing aids may effect when you might wish to purchase a hearing aid. For example, original hearing aids were analog, so they were made with a specific hearing loss in mind. If your hearing changed past a reasonable range covered by your hearing aid, it might have been necessary to purchase a new one. Now, analog programmable hearing aids are adjustable, and can be programmed by an audiologist to suit your fluctuating hearing loss. Finally, and most expensively (also: what I wear) are digital programmable hearing aids. My audiologist is able to test my aided and un-aided hearing, compare it to my hearing aid programs (plugged into the computer) and change my hearing aid levels very quickly. As someone with a permanent progressive loss, this type of hearing aid is helpful because my hearing aid adjusts as my hearing does. In general, it is advisable to get a hearing aid if you have trouble hearing, if your hearing loss is affecting your relationships with others, if your safety is affected while driving, working, or at home, or if you are unable to adjust to a more physical form of communication (cued speech, American/British Sign Language, SEE, Simultaneous Communication, lip-reading, etc.). As far as hearing levels go, a minimum loss is 26-45 decibels, and your purchase of a hearing aid truly depends on the above questions as to whether or not it will be beneficial. If you believe you have a hearing loss, please consult an Ear/Nose/Throat specialist to rule out any other possibilities besides a permanent hearing loss. After that, take their advice regarding seeking out an audiology specialist to assist you in choosing which particular device would be most beneficial to you!

When Is It Time to Get a Digital Hearing Aid?
So you finally decided that it was time to give in and purchase a hearing aid, but now you have no idea where to go or who to turn to when purchasing one. Don’t worry, the process of getting a hearing aid is simple if not always cost-friendly. There have been some definite breakthroughs in hearing aids over the past decade, and that is only going to benefit you. While hearing aids can certainly be expensive, how can you put a price on the ability to hear your friends and loved ones? One of the very first things that you are going to want to figure out is how much money you want to spend on your hearing aid. Unfortunately, most insurance companies do not cover the cost of hearing aids. Therefore, you are likely on your own. If you are part of a HSA or Health Sharing Plan, you may be able to put some of your money towards the hearing aid. Even if you think your insurance isn’t going to cover it, it is best to contact them just to make sure because some will. Now that you know how much you want to spend you want to decide what type of hearing aid you get. You will want to decide between a ‘in-the-canal’, ‘in-the-ear’, or ‘behind-the-ear’ hearing aids. I would explain further, however the names are actually pretty self explanatory in and of themselves. Finally, you are going to have to decide if you want to get an analog or a digital hearing aid. As you can imagine, the digital hearing aids are more expensive, however they have a much better quality of sound. Digital hearing aids are basically the same as analog hearing aids, except for a few key differences. A digital hearing aid actually can filter out noise and only allow the noises you want to come through come through. It gives you better volume control, a clearer sound, and also noise reduction. These key features are what make a digital hearing aid worthwhile. The bottom line is that you are going to want to find a hearing aid that fits your exact needs and your exact price. There is no use looking at high-tech hearing aid if you don’t have the coin to back it, but there are plenty of options out there to help you find hearing aid that fits you best.
