Disclosed is an audiologic test apparatus, system and corresponding method for performing an audiologic test in an ear canal. The audiologic test apparatus is configured to: generate by a tone generator a first electrical signal representative of a first signal with a first primary frequency component at a first primary frequency； receive a first response signal； determine if a first insertion criterion is satisfied, wherein the first insertion criterion is based on the first signal and the first response signal； and initiate the audiologic test if at least the first insertion criterion is satisfied. The audiologic test comprises generating a second electrical signal representative of a second signal with a second primary frequency component at a second primary frequency, wherein the first primary frequency is lower than the second primary frequency.
