One size does NOT fit all when it comes to hearing aids. At Fairbanks Hearing and Balance, we use best practices to fit hearing aids by using Real ear measurements. Real ear measurements are the gold standard used to determine whether or not a hearing aid user is receiving the precise level of amplification needed at every frequency in order to achieve the best hearing improvement possible. Depending on the level of hearing loss, 100% audibility is not always achieved, but the goal is to maximize the benefit to get as close to 100% as possible.
