Hearing evaluations for the purpose of fitting hearing aids
Complete audiometric hearing evaluations are provided for the purpose of fitting hearing aids to those who are effected by hearing loss . Tests include Air and Bone Conduction testing, Speech Reception Threshold Testing,(SRT) Most Comfortable Level (MCL), Uncomfortable Level (UCL) Discrimination or Word Recognition Testing, and Impedance Testing.


Hearing aid selection
Based on the hearing loss, the patient health history and life style the style and power range of the hearing aid is selected as well as which type of earmold, receiver in the ear (RIC) or thin tube will be most appropriate.


Ear impressions for making custom earmolds, communication molds, swim plugs and hearing protection
If earmolds are required for the hearing aid fitting, they are taken at this time and the specific style is selected based on the degree of the hearing loss.


Fitting hearing aids, programming hearing aids and verification testing of the hearing aids
The fitting session occurs one to two weeks following the initial test and consultation. The hearing aid is fit to the patient and a probe microphone in inserted into the ear canal with the earmold, Receiver in the ear or the thin tube. The probe mic is used to measure and verify the output of the hearing aid to insure that the amplified sound is matching the desired target gain. Adjustments are made to the frequency range, amplification gain and maximum power output of the hearing aid. Adjustments will also be made to the compression which controls the output of loud sounds. Programs may be selected for better hearing in difficult listening environments or for the use of the phone.


Counseling and instruction
Time is taken to insure that the patient is knowledgeable about the use and care of the hearing aids so they may be able to maximize the benefit of their instruments and any given listening environment.


Aural rehabilitation
AR involves specific exercises that are provided as well as general information about hearing, hearing loss and the hearing aids to enhance the transition time of adjusting to hearing sounds the patient may have been missing for many years and becoming comfortable with the use of their new hearing aids.


Follow up service during the trial period
At the end of the fitting session, the patient will be scheduled for the first of their follow up sessions. There may be several of these sessions as we want to insure that the hearing aids are adjusted correctly and that the patient is adjusting to the hearing aids after having had time to use the aids in their home and work environments. All hearing aids fit in the state of Oregon come with a 30 day trail period to insure consumer protection. Administrative Rule now requires at least one follow-up visit during the 30 day trial.


Follow up service beyond the trial period
Once the trial period is over, regular check up visits are recommended. We send out postcards every six months as a reminder of the needed cleaning and service of the hearing aids.


Hearing aid maintenance and repair
We maintain an onsite hearing aid repair technician who is in the office on most Tuesdays.
