Hi Muhammad, thanks for the answer. However I'm not looking for artifact removal pipelines, I'm quite well equipped and experienced with that already. I am looking for a device to present a white noise signal, aurally, to my participants. We've typically used ear plugs to mask the click but since the Conde paper in 2019 it's become more common practice to use white noise masking for reducing multi-sensory stimuli, the down side is we have limited space and want to avoid using a laptop to do this.

Paul Christopher John Taylor

Hi Nik,

We've played white noise to participants just using headphones and an ipod - and they couldn't hear the TMS pulse anymore (tried it myself too)... Incidentally did you see one fun-looking way to come up with noise is to play around with the TMS sound itself like in Herring et al. 2015 (J Neuro 35(43):14435–14447), although haven't tried that ourselves yet.
