part of a man\’s life is getting old. Once you have felt that the years are passing through, you also notice some changes in your body. There is one change though, that is quite normal with every person entering this phase in life. It is definitely by being hearing impaired or let us say, hearing only faint sounds. Knowing that you have this problem called hearing loss may be very devastating. How do you go through this period of time and still be on track? More likely you would need to use Hearing Aids. However, a lot of us might ask how do hearing aids work? Let us find out the answer to that.

The most overwhelming factor for senior citizens of how a hearing aid works is the technology behind it. Most adults have a time embracing the fact that technology runs almost every gadget that helps us live by especially things that we ought to attach to our body for it to function accurately. Hearing aids are gadgets that have been here for years. The first ones are cone-like devices that you hold up to your ear so a person can speak into it. It works just like a funnel. Now that we are in modern times, hearing aids improved in degree of technology. All of them have the same parts and mechanisms. So how do hearing aids work?

First of all, hearing aids have microphones. Just like how normal microphones are, they make the sounds louder but in this case, a small microphone is being used. Sound that comes in gets transferred into digital signal and once it is transformed into data, it will then revert back to sound again but now in a much louder volume. There are hearing aid microphones that are set for a specific type of hearing loss and user environment so that one may customize or choose for their own comfort. There are hearing aids with a directional microphone, meaning, you may choose to only amplify sound coming from in front of you to help reduce background noise.

Most people needing hearing aids consult the help of Audiologists. These are specialists who concentrate on the needs of a patient. They would normally ask you questions to know more about what type of hearing aid you are looking for. Some questions may consist of the type of noises you hear, if you need to hear them, or the factors that prevent or help you from listening accurately. All these questions will prove to be very helpful in finding the exact adjustment for your hearing aid.

After you have answered all the questions, the audiologist in return will adjust the hearing aid based on the specifications like volume, and direction of the origin of sound. Still about technology, there are three types that receive and convert the signals in hearing aids. They are the analog which is adjustable, another is also analog but programmable, and the third one is the digital programmable hearing aid.

The Adjustable Analog is the cheapest of the three. This type of hearing aid, as how it is called, is adjustable by the audiologist as per the patient\’s specifications. It will then be produced for you and you can either control the volume or have it automatically done. The Programmable Analog is another type of circuitry. These are somewhat better than the adjustable because it is programmed by the computer. Programs are used by audiologists to capture sound and transmit them into various listening scenarios. They are operated usually by a remote control and the user may select which program to use at any given time. Digital Programmable hearing aids, compared to the previous two, are more advanced in nature. It is also the most costly of the three. It contains a feature called DSP (Digital Sound Processing). It uses a computer chip to analyze the data before it is transmitted to the ear. It is also capable of detecting and eliminating feedback by identifying its frequencies. It is also user friendly.

Of course, every electronic gadget is operated with a battery. Most battery types for hearing aids last for 5-6 days depending on the type you get. Digital hearing aids provide more features and therefore, require more battery power resulting it to last for only a few days. Definitely, the selection for hearing aids is vast. And to feed our curiosity on how do hearing aids work, ponder on the ongoing innovations and search for improvement to make lives easier for us and you will find the answer.
