There has been much advancement in the hearing aid industry in the last few years. Hearing aids come in even smaller, discreet sizes, and yet still providing a high level of sound quality. Nowadays, most hearing aids are digital, replacing the analog version. While analog hearing aids were the least expensive, digital hearing aids are now available at affordable prices.

Digital hearing aids come in a variety of styles and sizes. The 4 basic styles are completely-in-the-canel (CIC), in-the-canal (ITC), in-the-ear (ITE) and behind-the-ear (BTE). The first three styles are custom made as an impression of the ear opening needs to be taken for making the hearing aid shell. The type of hearing aid you choose should be based on the type of hearing loss you have. A hearing care professional can help you decide which is best for you. Generally, the smallest units are not strong enough to provide for severe or profound hearing loss.

Digital hearing aids provide for flexibility because they have programmable features that can be customized to your specific needs. You do not need to adjust the volume on them as it is done automatically. There are different types of volume adjustments that resolve distortion and amplification problems. Digital processors use filters to clean up the sound and thus provide the best quality sound available.
