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 !

...or the MRI scanner, if it is a 3T or 4T, would fry the headphone.

Lots of luck,

Hi Guillaume,

 

I think the metal components in active-noise cancelling headphones would probably destroy an MRI scanner.

 

Cheers

Subject: [AUDITORY] Psychoacoustics with active-noise cancelling headphones

 

Dear list,

I would like to know if someone has ever tried to conduct a psychoacoustics experiment with active-noise cancelling headphones.

I am wondering whether existing devices would be good enough to cancel out a wideband background noise (such as a train interior noise) and playback stimuli with sufficient accuracy.

I have been happy with insert earphones for experiments within an MRI scanner, but I wonder if less expensive consumer audio devices could do the job for environmental background noises.

Many thanks !

Guillaume Lemaitre
