Real ear verification is the measurement of sound pressure levels in your ear canal that is developed when wearing a hearing aid. Our hearing specialists use real ear verification to ensure your hearing aids are providing you with the proper amplification to hear in different environments.
In the past, hearing evaluations and fittings for hearing aids consisted mostly of a series of beeps and noises. Today, Audiologists are equipped with new technologies and methods to make the hearing evaluation process and hearing aid programming process more effective.
One of the most advanced technologies available is live speech mapping, a method of fitting hearing aids using speech as a stimulus to help the Audiologist adjust hearing aids to the right settings for each wearer. Live speech mapping makes fitting appointments more scientific and objective, which can reduce the number of office visits required for successful hearing aid programming.
Why Perform Real-Ear Verification?
The goals of real-Ear verification are to ensure the speech spectrum is audible within the patient’s residual dynamic range and to match the gain and output of the hearing aid against the patient’s hearing loss and evidence-based prescriptive targets. But how important are these goals, and do manufacturer prescriptive strategies provide adequate gain?
Research has proven that the use of real-Ear measurements with manufacturer first fit settings have consistently shown that first fit settings typically under-amplify the high frequencies. We know that researched and validated prescriptive targets, and the ability to “meet” them with real-ear measurements, ensure that we are providing the best access to acoustic information delivered to your hearing aids.
