Subject: Re: [AUDITORY] Psychoacoustics with active-noise cancelling headphones From: Guillaume Lemaitre <guillaumejlemaitre@xxxxxxxx> Date: Wed, 19 Sep 2018 08:09:32 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--000000000000bce00105763340b7 Content-Type: text/plain; charset="UTF-8" Dear list, Sorry I wasn't clear: I don't want to use them in scanner but on a train, I was just mentioning MRI-compartible earphones because I had good results with them (to cancel out the scanner noise), and I would like to achieve similar results with less expensive devices, whithin train, to cancel out the train background noise. Thank you !
