Sufferers of hearing loss can benefit from hearing aids that amplify the sounds around them to allow them to comprehend what they are hearing. Their tiny microphones and speakers increase the volume of sounds the wearer hears allowing them to lead a better life.
They often allow the wearer to lead a much better life with a greater level of interaction with what goes on around them. It's a pity that only a small percentage of the people who would benefit from a hearing aid actually get to wear them. With improvements in medical treatments around ten percent of hearing loss sufferers can benefit from medical treatments without the need for a hearing aid.
There are now a lot more different devices which vary according to the different types of hearing loss. The majority of hearing aids can be separated in to two different types by how they are worn.
A Canal Aid is a device that is worn in right inside the ear canal making them invisible from view. They can be shaped to fit to improve efficiency and to make them more comfortable for the individual wearer. These devices are worn by patients with different levels of hearing loss ranging from mild to quite severe.
Another category of hearing aids is the 'In the Ear' devices that fit in the outer ear. Compared to devices that are worn outside of the ear these are still fairly unnoticeable. People with hearing loss ranging from mild to severe can benefit from these devices and they are also easier to remove and replace than the canal aid types. Telecoils can often be used with these kinds of devices and they tend to have the added benefit of a volume control.
Behind-the-ear hearing aids have an ear mold placed at the back of the ear and connect to a speaker in the outer ear. The earmold contains the microphone and amplifier for the device. The behind- the-ear type devices are more beneficial for people suffering from the severest hearing problems but are considerably more noticeable. These devices though can sometimes have problems associated with feedback such as a whistling sound.
Two different audio technologies can be used in hearing aids and the different types have both advantages and disadvantages. The different technologies, analog and digital, both have advantages and disadvantages when it comes to their use in hearing aids.
Analog hearing aids work by producing an electrical signal from sound waves. These types of devices can be set depending on the needs of the individual. These devices can also be adjusted to suit the environment by the wearer themselves, such as quiet, enclosed spaces and when traveling in a vehicle.
Digital devices, although more expensive are able to be programmed with more features and can achieve greater control over the sound quality. The audio quality can be improved significantly and background noises can be reduced or have more clarity. Digital hearing aids also tend to be more comfortable and convenient, because sound levels adjust automatically as the environment changes.
Nowadays the hearing aids that are available have improved dramatically with time and are more practical to wear and less obtrusive. People thinking about getting a hearing aid should discuss the different hearing aids that are available with a professional audiologist. People can go on to lead more fulfilling lives with the right hearing aid, with more clarity in their hearing they can interact more and able to participate more, generally making life a lot of more rewarding.
