Real ear measurement (REM) is a technique used in audiology to assess how well hearing aids are working in a patient's ear by measuring sound levels directly in the ear canal. This process involves placing a thin microphone in the ear while the hearing aid is in use, ensuring the device is providing the correct amplification for the user's specific hearing loss. By obtaining accurate data through REM, audiologists can fine-tune hearing aids for optimal performance, leading to improved hearing experiences for individuals.

Send FeedbackReal Ear Measurement (REM) is a crucial technique used in audiology and hearing aid fitting. It involves measuring the sound levels in a person's ear canal while they are wearing hearing aids. This process ensures that the amplification provided by the hearing aids matches the specific hearing needs of the individual.
Real Ear Measurement helps audiologists fine-tune hearing aids for optimal performance. This is important because every individual's ear anatomy is different, and the way sound travels in the ear can vary significantly. REM typically involves the following steps:
For instance, if an individual requires certain frequencies to be amplified more than others due to their hearing loss, REM allows the audiologist to see how the hearing aid performs in real-time and make precise adjustments. This ensures that the amplification is tailored specifically for the individual’s hearing profile.
It's essential to conduct REM in a quiet environment to ensure accurate measurements and adjustments.
When performing Real Ear Measurement, understanding the concepts of target gain and real-ear insertion gain is fundamental. Target gain refers to the amount of amplification prescribed for each frequency based on a person's audiogram. It is the ideal amplification level needed to help the individual hear sounds in their environment. On the other hand, real-ear insertion gain is the difference between the sound level in the ear canal with the hearing aid and the sound level without it. This measurement helps audiologists fine-tune the device to ensure it provides the intended amplification. Factors that influence REM include:
Real Ear Measurement (REM) is a method used to assess the performance of hearing aids within the context of an individual's ear anatomy. It involves measuring sound levels in the ear canal while the hearing aid is in use, thereby ensuring that the device provides adequate amplification tailored to the user's specific hearing loss.
REM is crucial for effective hearing aid fitting as it accounts for the unique characteristics of each person's ear. The process typically unfolds in a few systematic steps that focus on gathering accurate data:
For example, if a patient has a high frequency hearing loss, Real Ear Measurement will reveal whether the hearing aid is sufficiently amplifying the necessary frequencies. The audiologist can then revise the settings to ensure that these sounds are not just audible but comfortable and clear for the listener.
It's recommended that Real Ear Measurements be performed in a controlled environment to minimize any external noise that could affect the accuracy of the readings.
Understanding Real Ear Measurement involves knowing key terms such as cutoff frequency, target gain, and real-ear gain. The cutoff frequency is the point at which sound amplification begins and is critical for hearing aids that cater to different frequencies. Target gain indicates the desired amplification level based on the user’s specific audiological needs. It is derived from detailed audiograms that reflect the user’s hearing capabilities. Real-ear gain, on the other hand, measures the actual sound level achieved in the ear canal compared to the level without the device. These measurements allow for precise tweaks to ensure that hearing aids perform optimally in various environments. Moreover, REM is essential to distinguish between desired and undesired sound levels, helping to adjust the device for better speech understanding without distortion of sound or discomfort.
Real Ear Measurement (REM) is a technique used in audiology to detect sound levels within the ear canal while a person wears their hearing aid. This method allows for precise adjustments to the device's amplification settings to meet the individual's hearing needs.
The process of Real Ear Measurement involves several crucial steps:
For instance, if a user struggles to hear high-frequency sounds, Real Ear Measurement can reveal whether the hearing aid is delivering sufficient amplification in that frequency range. Consequently, an audiologist can adjust the settings so that these frequencies are adequately addressed, enhancing the overall listening experience.
Performing REM in a quiet room helps ensure accuracy in measurements, leading to better hearing aid adjustments.
Delving deeper into Real Ear Measurement, it’s important to understand how various parameters influence the results. Critical terms related to REM include target gain and real-ear insertion gain. Target gain is the level of amplification prescribed based on a person's audiometric profile, indicating how much each frequency should be increased for optimal hearing. In contrast, real-ear insertion gain reflects the actual difference in sound level within the ear canal when the hearing aid is worn versus when it is not. REM can vary based on factors such as:
The Real Ear Measurement procedure is an essential process to optimize hearing aid fitting. It helps ensure that the settings of the hearing aids correspond to an individual's unique auditory requirements. The procedure consists of several critical steps:
For example, if a hearing aid is programmed for a specific gain level but the REM reveals that the sound level in the ear canal is too low, the audiologist can increase the gain in those frequency ranges. This targeted adjustment is key to providing effective hearing support.
Remember to conduct the Real Ear Measurement in a quiet environment to avoid interference from background sounds, ensuring the accuracy of the results.
During the Real Ear Measurement process, understanding certain technical aspects can greatly enhance the fitting accuracy. Some important concepts include:
