Acoustic Memory Test
IntellectualHear a spoken sequence once, hold it through a filled delay, and type it back — exactly in order.
Overview
The Acoustic Memory Test measures short-term retention of spoken material with delayed recall — the documented acoustic-memory block of the DLR selection for the Lufthansa Group, and the skill behind holding a multi-part clearance until it is read back. Sequence lengths, pacing and the typed response format are our own design; the module itself, and its delayed-recall character, are publicly documented. TestAir360 mode is the acoustic memory test of Wizz Air's TestAir360: ten series of seven digits, then five of eight, then five of nine, each typed back the moment it ends.
Assessments
Tested in assessments at Lufthansa Group.
Could show up in DLR and TestAir360-based selections.
Airline mappings are based on public information and may change.
Example: one delayed sequence, start to finish
In the real test the items are spoken — the screen never shows them. The trial below is written out so you can watch the whole cycle: playback, the filler that guards the delay, then ordered recall.
1 · Playback — once, by ear
2 · Filler — odd or even, while you hold on
3 · Recall — every position must match
"7" is spoken — the screen only pulses, it never shows the item. It plays once.
Example: one TestAir360 series
TestAir360 mode has no delay and no filler: a series of digits, then the answer strip. The digits are written out below; in the test you only hear them.
1 · Playback, once, by ear
2 · Recall, straight away
5/7 digits in place · the series scores 0
"4" is spoken. The screen never shows it, and it plays once.
Game Phases
Listen Once
Put on headphones and confirm the sound check. A sequence of spoken items plays exactly once — the screen only pulses to show that something played, never what.
Hold It
Immediate mode goes straight to recall. In Delayed and Challenge modes a parity filler task — click odd or even on digits that appear — fills the retention gap and blocks silent rehearsal. Take it seriously: in Challenge, every delay needs at least 70% of digits answered and at least 60% of your answers right, or the run will not rank.
Recall In Order
Type the sequence into the entry strip, one slot per item. Each element in its correct serial position earns a point; the recall timer gives 5 seconds per item in every mode, and in Challenge a submitted recall containing a mistake ends the run.
Climb the Span
Two fully-correct sequences in a row lengthen the next one; two rough ones shorten it. The span you reach is a first-class result alongside your score. TestAir360 mode has no climb: its lengths are fixed at seven, eight and nine digits.
More Practice
Memory
10 exercisesENAC M2-back numérique
Digits come up one at a time, a new one every 3 seconds. From the third one on, you say for each digit whether it's the same as the one 2 before it. The exam format is 62 digits, 60 of them with a question.
ENAC M2-back couleurs
Coloured squares come up one at a time. From the third on, say whether each one is the same colour as the one two before it. The exam format is 42 colours, 40 answers, in 2:06.
ENAC Memory N-Back
Letters come up one at a time, and for each one you say whether it’s the same letter as the one three, four or five before it. Capitals and small letters count as the same. The exam format is two tests back to back: a 3-back then a 4-back for ENAC EPL, a 4-back then a 5-back for Air France Cadets. It hasn’t been set since 2020.
Visual N-Back
Shapes in colours go past one at a time. On every one, say whether it is the same shape AND the same colour as the one a few places back — and the lag you are matching against changes from block to block.
Associative Memory
Memorise a set of symbol–number pairs, then after a short delay recall which number went with each symbol.
Parameter Memory Test
Aviation parameters flash up on a dark display, then vanish. Reproduce the data row by row, from memory, before the clock runs out.
Grid Challenge
A dot memory test in the format of gridChallenge, Aon's official name for its working memory module: dots flash one by one on a scattered field, quick yes or no puzzles interrupt between flashes, then you click the dots back in order.
ENAC Memory Calculation
You get a calculation, then a letter, then another calculation and another letter, and so on. At the end of the board, you type the letters back in the order they came. The exam format is 20 boards, from 3 letters up to 9, with 5 seconds a calculation and 1 second a letter.
ENAC Running Comparison
A stream of simple calculations, one at a time. For each one, tick whether its result is identical to or different from the one it's compared with: the result just before, the one two back, or a fixed value X, depending on the block. The exam format is 100 answers in four blocks of 25, about 12 minutes.
ENAC Reversed Series
Digits come up one at a time in the same spot, a second each. When they’ve gone, you type them back in reverse, the last one first. The sequences grow from 4 to 9 digits. The exam format is 12 sequences, about 3:30.
