Real ear measurement, also referred to as hearing aid verification, is a method to objectively measure what a hearing aid is doing in the ear canal. Affinity Compact, Affinity 2.0, and Callisto™ can all perform real ear measurements.
A hearing aid test box is a sound-isolated chamber used to measure and verify hearing aid performance. They can either be standalone or embedded within a hearing aid fitting system. Interacoustics offers the TBS25 and TBS10 standalone hearing aid test boxes.
A hearing aid test box conducts valid measurements of hearing aid performance. This includes digital signal processing (DSP) functions such as directionality, noise reduction and feedback suppression. You can also use test boxes to test bone-anchored hearing instruments and for coupler-based hearing aid fitting.
