What are hearing aids?
Hearing aids are small electronic medical devices worn on or in the ears. They amplify sound in a person's environment to help them hear better.Hearing aids are typically programmed and monitored by a hearing care provider who has training and expertise in hearing loss and hearing aids. A hearing are provider can help you determine if hearing aids are a good fit for you.
Hearing aids are usually recommended for people who have a type of hearing loss known as "sensorineural," meaning that some of the tiny hair cells of the inner ear are damaged. The surviving healthy hair cells pick up the sound delivered by the hearing aid and send them as neural signalsto the brain via the auditory nerve.
The parts of a hearing aid
All hearing aids contain microphones to detect sound in a person's environment. A tiny computer processor inside the device then analyzes the sounds and amplifies them according to a person's unique pattern of hearing loss. These sounds are delivered to the ear via a speaker that sits in the ear canal.

Hearing aid fitting
Onceyour hearing healthcare professional recommends hearing aids for you, a number of factors will be considered whenselecting and fitting a device.
The best fit for you will depend not only on the severity and type of hearing loss you have but also your budget, cosmetic preferences, career demands and other concerns.
Because hearing aids are personalized, not every brand, style or technology level of hearing aid is suited for everyone. Even two people with the same hearing loss may end up with different hearing aids based on other selection criteria.It’s best to talk to your hearing healthcare provider about what options and features are ideal for you.
Will I hear better right away?
Yes, but your new hearing aids may take some time to get used to. Hearing healthcare professionals will perform an initial fitting where they fine-tune features and adjust levels to ensure you are getting the most benefit from the devices.
It is important to note there is an adjustment period when wearing new devices, and it takes time to get used to new hearing aids, even if you’ve worn some type of hearing aid for many years. Be patient with yourself and communicate with your provider about any issues you are having.
