In the field of audiology, new technologies are being developed all of the time to improve hearing aids. Newer technologies sometimes mean more convenience and advanced features, but their cost can be prohibitive and they can be difficult to figure out at the beginning. The older technologies are often cheaper and less complicated to use, but they lack the sophistication of the newer devices.

Even with newer technologies, analog hearing devices are still the primary choice for some users. One of the main reasons for this is that these aids are the least expensive type. They are seen as generic and are generally appropriate for most types of hearing loss. Some of the drawbacks of analog hearing aids is that they pick up all of the surrounding noise and they don't do a good job of differentiating between sounds.

Analog hearing aids come in programmable varieties in order to acclimate to the wearer's level of hearing loss. These tend to be more expensive than the standard analog aids. These types of devices will need to be programmed by your audiologist to the frequency that is suited for your hearing loss level.

Digital hearing aids use numerical processing to convert sound waveforms. The advantages of a digital hearing aid over an analog version are said to be increased compression within the hearing aid and consequently better audibility, with less low-level background noise. As a result, the aid wearer can more easily distinguish between background noise and speech. Digital aids can be programmed as well.

Some hearing aids come with directional microphones. These microphones pick up the direction from which sound is coming. The sounds that are coming from places in front of the hearing aid wearer are the ones emphasized over the sounds coming from behind the wearer or from the side of the wearer. These are helpful when the aid wearer finds themselves in noisy areas, such as city sidewalks or sports stadiums.

Hearing aids with Bluetooth technology allow for their wearers to hear while using Bluetooth cell phones. These hearing aids use wireless technology to pick up the Bluetooth signal. The good thing about these devices is that holding the phone to your ear is not required in order for them to work properly.

In order to find the best hearing aid, you should see an audiologist, who will help you find one that fits your ear canal and complements your lifestyle and needs. If you are interested in finding out how a particular hearing aid suits you, request that your audiologist permit you to wear one on a trial basis. You will also need to check with your health insurance company to find out which devices they will cover, and if there are any restrictions.
