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



Hi Guillaume,

 

It would probably be best to still use insert phones to ensure that your stimuli are not affected by the signal processing in the noise cancelling headphones.     Good quality insert phones are available from

 

Etymotic https://www.etymotic.com/consumer/earphones/er4-new.html that might be of use.

 

Cheers

 

Neil

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 !

Guillaume

Lots of luck,

Hi Guillaume,

 

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

 

Cheers

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 !
