The modern hearing aids of today are usually programmed using a computer in one way or another before they are fitted. The technology of Hearing Aids GA was designed to give a fitting that is more precise. An audiologist uses this tool that is relatively new to give you the hearing experience that you desire.
The GA, for Hearing Aids GA, is for genetic algorithms. Firstly, is to look at what algorithms are so as to understand them. An algorithm is determining how something gets done. There are often different ways to do something to achieve a goal. The algorithm is the chosen way of doing something. All algorithms have their advantages and disadvantages, although they all accomplish the same goal basically. We all have varying pathology so we have our own unique algorithm which is used to program a digital hearing aid so that it fits with good results. Each result is different for each user for the fitting of their hearing device.
These algorithms are so called genetic algorithms because the elements found in biological genetic principles are mimicked. One example is natural selection where a set of parameters is discarded if it is found to be weaker or less useful than another set, that is, it does not get selected. Hearing Aids GA does have a few possibilities but is able to do the job of rating each selection and picking out the best one for you.
This will be done when you go for your fitting. The audiologist will normally give you two options as presented by the Hearing Aids GA, and you select the one which you find better. It carries on giving you two options until all the information is processed to arrive at a conclusion according to your preferences.
In one study, subjects with normal hearing were tested by being given speech sounds that were distorted to listen to. The Hearing Aids GA looked at their preferences and programmed to give the overall best solution for the problem, which it did in most cases. A second study was done with the subjects to see if the same preferences came up again in the feedback from a second time. Indeed they were. This technology is proven to give an accurate fitting for the majority of individuals which is excellent.
In order for it to be practical long term and continue to be effective, they should be capable to adjust to a user's change in preferences. Artificial intelligent design is important in these instances in being responsive to the wearer's actual use.
Some Hearing Aids GA now come with Bluetooth technology so that it be downloaded to a program which communicates with the hearing aid. There is where the audiologist comes in as they are the only one professionally trained to do the fitting. They are not developed enough that you can do it by yourself.
It is a great advantage having hearing aids that are digitally programmable. The programming is the most important part and that is what Hearing Aids GA does, so that you get a fitting which doesn't take long and is as accurate as it can be.
