Ahlberg Audiology & Hearing Aid Services

On average, most people don’t know how to recognize the first signs of hearing loss because it most often occurs gradually and is an invisible issue that can be disregarded initially without realizing there is a problem. Many times it is friends and family that notice the loss first because the person with the hearing loss mistakenly thinks other people are mumbling or not speaking clearly and doesn’t realize the difficulty is with their ability to hear. If you suspect you or a loved one may have a hearing problem, it is recommended you have your hearing evaluated by an audiologist. An audiologist is a hearing care professional specializing in identifying, diagnosing, treating and monitoring disorders of the auditory and vestibular system. They are trained to diagnose and treat hearing loss, tinnitus and/or balance problems.   

Every day we hear a variety of sounds. Sounds that are too loud, or loud sounds over a long time, can damage your hearing.

The loudness of sounds is measured in decibels (dB). Learn the decibel levels for different sounds and know which noises can cause damage to your hearing.

Protect your ears when you are involved in a loud activity.
