Real Ear Measurement (also known as REMs or Probe Tube Measurement) is the measurement of sound pressure 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 the performance of a hearing aid.

First, the clinician will examine the ear canal with the use of an otoscope to ensure no wax or other debris will interfere with the positioning of the probe tube. The probe tube is placed with the tip 6-8mm from the tympanic membrane. Next the hearing aid is put in place. The REM system will typically produce a test stimulus from a loudspeaker situated 12-15 inches from the patient's head and simultaneously measure the output in the ear canal to determine how much amplification the hearing aid is providing.
