Abstract
In-situ measurement comprises two consecutive measurements (open ear gain and in-situ gain), from which a result is formed by forming a difference. For the two measurements, it is important that the in-situ tube is positioned in the same place in the auditory canal. Otherwise there are different level and phase ratios, such that the result obtained from the formation of a difference is not meaningful. Thus, the in-situ tube is permanently connected to the ear plug, as a result of which the positioning of the in-situ tube remains the same for both measurements.
