  the article won't say how much though. Did you read TFA? "However, the average improvement was three times larger after pink-noise stimulation."

    Three times larger than "a few percent". So, somewhere between three and six percent, I guess. Meaning that if the test set consisted of 20 items, they remembered on average one more.

      The study was done on 13 people for one night in the lab. It's an interesting result, no doubt, but to make any practical conclusions I'd wait for someone to replicate it for thousands of people after months or even years of at home use.

      And the study had 13 participants. They did two runs one with the snake-oil noise and one without. Can you even call it a study? With such a small numbers the study can show any random thing you want, from reducing feet odour to increasing yawn count. Even if it worked it's poorly designed because it assumes that the benefits fade away, ie. are not present on the 2nd day. Would be probably better to split them half and give stimulation then sham and for other half other way around (tip. don't split one senior in half!).
