What is Real Ear Testing? #
Real ear testing (REM) is a type of hearing test that measures the performance of hearing aids in the ear canal. It is a more accurate way to measure hearing aid performance than traditional methods, such as audiometric testing.
What are Real Ear Measures Used For? #
Real ear measures are used for a variety of purposes, including:
- Fitting hearing aids: REM can be used to ensure that hearing aids are providing the correct amount of amplification in the ear canal.
- Monitoring hearing aid performance: REM can be used to track how hearing aids are performing over time and to make adjustments as needed.
- Research: REM is used in research studies to evaluate the performance of new hearing aid technologies.
What is Real Ear Gain? #
Real ear gain (REAR) is a measure of the amount of amplification that a hearing aid provides in the ear canal. It is calculated by subtracting the sound pressure level (SPL) of a sound in the ear canal without the hearing aid from the SPL of the same sound in the ear canal with the hearing aid.
What is a Real Ear Aided Response? #
Real ear aided response (REAR) is a measure of the sound pressure level (SPL) of a sound in the ear canal with the hearing aid turned on. It is calculated by subtracting the SPL of a sound in the ear canal without the hearing aid from the SPL of the same sound in the ear canal with the hearing aid.
How is Real Ear Testing Performed? #
Real ear testing is performed using a real ear analyzer, a specialized piece of equipment that measures the sound pressure level (SPL) of sounds in the ear canal. The real ear analyzer has a probe microphone that is inserted into the ear canal. The probe microphone measures the SPL of sounds in the ear canal, and the real ear analyzer displays the results on a computer screen.
Conclusion #
Real ear testing is a valuable tool for fitting and monitoring hearing aids. It provides a more accurate measure of hearing aid performance than traditional methods, and it can help to ensure that hearing aids are providing the correct amount of amplification in the ear canal.
