Why 16 Hz

Paper tested 8 / 16 / 32 Hz at low/medium/high depth. Best result: 16 Hz at medium depth (F(1,80) = 4.03, p = 0.048). Effect strongest in high-ASRS listeners.

Find Your Best AM Rate

This is a 3-minute attention test, identical in structure to the one used in the paper (SART). You'll see digits 1–9 appearing one at a time.

Tap (or press Space) for every digit — except 3. When you see 3, do nothing.

The audio behind the test will run at 8 Hz, 16 Hz, and 32 Hz in a randomized order. We'll tell you which rate gave you the best score.

Use headphones if you can. Find a quiet moment — this only works if you're actually trying.
