Importance of regular check ups for hearing aids 

Patient’s mother walked in complaining that her daughter cannot hear anything from her hearing aids even with new batteries. Last visit was more than a year ago. 

Ran a test on the hearing aids in the AXIOM test box with speech input. 

Notice the compressed green lines with very little gain. This is with her current hearing aids before changing the weather protectors. 

Then compare it with the purple lines above it with more gain and greater dynamic range. This is after changing the weather protectors.

They may seem like just filters but notice the big difference with the new weather protectors. A good reminder to have your hearing aids checked regularly, especially  for children.
