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.
