Web17 feb. 2024 · In a child with ANSD, loud sounds don't trigger the reflex or much louder sounds are needed to trigger it. For the MEMR (also called an acoustic reflex test), a soft rubber tip is placed in the ear canal. A series of loud sounds are sent through the tips into the ears and a machine records whether the sound has triggered a reflex. sadly beautiful song
