Since they were invented, hearing aids have changed quite dramatically and now there is a wide range to choose from.

Another well known type of hearing aid is the 'in the ear' devices that fit inside the outer ear. These are more visible when worn than canal aids, but still often go unnoticed. Patients with mild or severe hearing difficulties can use these devices and they are also easier to adjust than the canal aid devices. Many of these types of hearing aids will have an adjustable volume levels and can come with a telecoil to help the wearer hear telephone conversations more clearly. The category of hearing aids known as 'behind the ear' aids have an earmold that tucks in the back of the ear. The amplification is carried out in the earmold behind the ear. The separate speakers allow these devices to help patients with more severe levels of hearing loss, but are also the most visible types. These devices though can sometimes have problems associated with feedback such as a whistling sound. Modern hearing aids available can be found using either analog or digital technologies. Analog and digital audio hearing aids both have their own pros and cons associated with them. Analog technology in hearing aids creates electrical singles and amplifies them. Analog devices can be tuned to the individual needs of the patient. Analog hearing aids can often be adjusted to suit the location and differing noise levels by the person who wears it. Digital hearing aids do tend to be the more expensive option but have the advantage that they are more customizable when it comes to the way in which the sound is amplified. Digital devices can result in less interfering background noise due to the higher quality of sound the produce. Digital hearing aids also tend to be more comfortable and convenient, because sound levels adjust automatically as the environment changes. Today, the hearing aids that are available provide the wearer with a much better hearing and are more comfortable to use and wear than those of the past.
