Devices arrive from the manufacturer with no prescription programmed. They are set to their default mode and require custom programming to match them to your hearing prescription.
For all hearing instruments that we prescribe, we complete real ear measurements to adjust the devices based on the way they fit and function in your ears. Research in audiology has showed that this step is essential, but far too many hearing aids are fitted without real ear measurements.
We use specialized microphones that are designed for the human ear canal to measure the output of your hearing aids when they are in your ears. You can expect to hear all sorts of sounds during the fitting process. Many of them will be enjoyable, but do not get discouraged if some sounds are annoying or too loud. The hearing aid fitting process involves measuring how the hearing aids are processing all sorts of sounds.
Following real ear measurements, your hearing aids will be set to your prescription.
We may make further adjustments to give your brain time to adapt to the extra sounds (including making the hearing aids quieter at first). Over time, we will work towards reaching your hearing loss prescription. This process and length varies for every individual, but Acoustic Audiology will provide the support to help you reach your highest potential.
