Real Ear Measurements Or Probe Microphone Measurements

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 and hearing aid programming process more effective.

One of the more advanced technologies available is Real Ear Measurements (REM) also referred to as Probe Microphone Measurements (PMM). This test verifies that the hearing aids are meeting your needs; it is an objective measures of how the hearing aid is performing in your ear. Everyone's ear canals are unique. Some ear canals are straight and cavernous; others are tortuous (twisty) and narrow. These differences of the ear canal can affect the amplified sound of the hearing aid; it can sometimes make certain sounds too loud or too soft. 

REM will measure the affects of your ear canal shape and help the audiologist fine tune the hearing aid. This is the most accurate way to make adjustments and should be conducted as part of your hearing aid fitting process. REM can reduce the number of office visits required for successful hearing aid programming.

What is live speech mapping?

Live speech mapping is the typical REM testing method. With this method, small microphones placed in the ear canal are used to measure the response of the hearing aid in your ear taking into account the natural and individual characteristics of both your ear and your hearing loss. 

Your audiologist will have high-tech equipment that will allow them to “see” what you are hearing through your hearing aids on a screen in real-time. You and your family members will be able to visualize and understand the differences that hearing aids can make with your hearing ability.

Benefits of live speech mapping

Live speech mapping helps the audiologist accurately program the hearing aids. Live speech mapping increases the chances that your hearing aid programming will be done correctly on the first try.

Live speech mapping also creates a much more positive fitting experience by allowing both you and your family to see the immediate results of your hearing aids and their positive impact on your ability to hear. Both you and your family will be engaged in the fitting process, making it a joint affair.

If you have a hearing loss, you may not be able to fully understand what you can and cannot hear, and therefore, you may not understand everything you are missing. With speech mapping, you will have the ability to hear the improvements immediately, and you will be shown exactly what you can and cannot hear in real-time.

Benefits live speech mapping:

  • Focuses on the important and basic function of being able to effectively hear human speech
  • Engages both you and your family in the fitting process
  • Provides immediate and tangible results
  • Shown to increase successful outcomes of fittings
  • Increases your confidence and comfort in using your new hearing aids
  • Provides more accurate programming of hearing aids
  • Reduces number of return visits

Ask your audiologist to verify your hearing aid fitting with REM.
