An audiologic test apparatus includes: a processing unit a tone generator connected to the processing unit and a probe interface for connecting the audiologic test apparatus to a test probe the tone generator configured to provide a first electrical signal representative of a first signal with a first primary frequency component at a first primary frequency wherein the processing unit is configured to: obtain a first response signal, determine if a first insertion criterion is satisfied, the first insertion criterion based on the first signal and the first response signal, and generate a signal to initiate an audiologic test if at least the first insertion criterion is satisfied the tone generator configured to provide a second electrical signal representative of a second signal with a second primary frequency component at a second primary frequency during the audiologic test, the first primary frequency being lower than the second primary frequency.
