Hearing Aid Fitting



So you have made the decision to try hearing instruments.  This is what to expect when you come into the clinic for your fitting appointment:

Step 1

The Audiologist will start by explaining the process to you and begin by inspecting your ear canals to ensure they are clear.  Your hearing instruments will be connected to the computer which is how the Audiogist is able to make acoustic adjustments during the fitting.  She will turn you toward the Real Ear Measurement machine and in our offices, we use the Verifit by Audioscan.  This equipment is the gold standard in hearing aid verification.  People often ask me, “Why not do a retest of my hearing in the sound booth and measure the improvement made by the hearing instruments?  This is the way we used to verify hearing instrument fittings in the old days. The problem with this method is that that the advancements in feedback and noise management have made this method less reliable. Often, the hearing instrument will confuse the pure tone sounds with feedback or noise and therefore will try to cancel these signals.

Step 2

The Audiologist will put a small microphone down your ear canal which will measure the output of the sound as it reaches your eardrum. Your new hearing instrument will then be placed on top of this microphone and the hearing instruments will be turned on.  At this point, there will be a variety of speech signals presented from the Verifit that will allow the audiologist to adjust the hearing aids in such a way that we can ensure the right amount of volume is presented at each frequency.  An important part of this measurement is ensuring sound does not exceed your loudness tolerance levels.

Step 3

Once the Real Ear Measurements are completed, the Audiologist will talk with you about your first impressions of the sound.  It is then likely that the Audiologist will turn the overall volume down a bit so as not to overwhelm you with sound at the first fitting.  Most people lose hearing gradually, so it is easier to adjust to amplified sound if we can give it back to you in stages as well.

Once the sound levels are set to a comfortable level for you, the instruments will be removed from your ears and the Audiologist will go over the following:

  • Battery insertion and use
  • Care and cleaning of the instruments
  • Insertion into the ear.
  • Operation of the volume control and program buttons.
  • Operation of the remote control (if applicable).
  • How to use them during and throughout your day.
  • How to use them on the phone.
  • What to do with them when they are not in use.
  • Counseling about the directional microphones and their function.
  • Ideas for adjusting to sound and how to manage noisy environments. Discussions on Auditory Training with programs such as LACE
  • What to expect in the first few days and weeks.
  • Connecting the instruments to any Bluetooth® accessories such as TV’s or cellphones.
  • Then we review the instruction booklet that comes with the hearing instruments.

Step 4

Once you are comfortable with the use of the instruments we will go over information on the warrantee of the instruments as well as the 90 day trial period.

Your follow-up appointments will then be discussed. Generally, two weeks following your fitting you will be booked for your first follow up. At this appointment, we will talk about if you are ready to increase volume or clarity, or perhaps decrease sound should you find that things are too loud.  It is very helpful at this appointment if you come to the appointment with some notes about your experiences over the first two weeks.

Step 5

Follow-up appointments will continue to be booked for you until there comes a point where you come into see the Audiologist and feel that there is nothing left to adjust because things sound great for you.  During these appointments it’s important to know that we often change the hearing instruments and start again with a new hearing instrument if it doesn’t seem we are getting close to meeting your expectations for hearing.  Sometimes the product we choose initially isn’t the one we end up with in the end.  Its important to realize that being fit with a hearing instrument is a process not an event, so we will work together until the end result is satisfaction on your part.

*It is this stage of the fitting that requires the most skill on the part of the Audiologist. Interpreting your impressions and coming up with the right solution is where the challenge lies in the fitting.  For some people, their hearing loss and needs are straightforward, while others require a bit more assistance it getting it sounding just right.  But whichever person you might be, we are committed to making the process smooth and simple for you and the end result will be a positive improvement in your quality of life.
