Getting used to a hearing aid takes time, usually at least a month to six weeks, but it may take as long as several months until your ability to understand speech has peaked.If you don't notice a marked improvement by the end of the first month, there's a strong chance that the hearing aid isn't right for you.nother factor is how much time you spend wearing your hearing aid when you first take it home. Many audiologists have found that the patients who keep their hearing aids in for the longest time each day in the first few weeks adjust the fastest.
Though they are certainly powerhouses of digital technology, hearing aids â as with all of our personal electronic devices â do not last forever. On average, hearing aids have an estimated lifespan of three to seven years. Depending on the style, some may last longer. In-the-ear hearing aids tend to last four to five years, while behind-the-ear hearing aids have a five to six year lifespan. This is due to the construction of the hearing aid, and the way they are worn. In-the-hear hearing aids are exposed to more moisture and higher temperatures due to the way they are worn.
