The invention relates to a terminal (10) for a defibrillator, including a casing (20) and a removable defibrillator (100) placed in a recess (30) in the casing (20), such that the defibrillator (100) can be removed from the recess (30). The defibrillator includes means (105) for emitting a test sound vibration and the casing (20) includes means (25) for detecting the test sound vibration emitted by the defibrillator (100). The terminal (10) is characterised in that the detection means (25) include a means for filtering sound interference.
