Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.

Earplugs with probes for MIRE measurements. Also referred to as F-MIRE (field microphone in real ear). This method measures attenuation by placing a small microphone inside the ear canal while hearing protection is worn. Sound pressure levels (SPL) are measured inside and outside of the ear simultaneously and used to calculate a PAR. [24]
The most reliable method for assessing the correct adjustment of a hearing aid is through real ear measurement. [10] Real ear measurements (or probe microphone measurements) are an assessment of the characteristics of hearing aid amplification near the ear drum using a silicone probe tube microphone. [11]
Real-Ear Measurement is a verification method that ensures the output of your hearing aids is fit properly. It's one tool audiologists use and is considered the best practice in the industry.
Visit a hearing care professional who utilized Real Ear Measurements (REM) after the OTC purchase to confirm if the hearing aids apply the appropriate volume amount based on your hearing test.
Hearing protectors sold in the US are required by the EPA to have a noise reduction rating (NRR), [40] which is an estimate of noise reduction at the ear when protectors are worn properly. Real-ear attenuation at threshold (REAT) measurements are performed multiple times with 10 to 20 subjects to determine the NRR.
The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with effusion"). Compliance measurement indicates how well the eardrum and ossicles (the three ear bones) are moving.
