Hi Victoria,In terms of soundcards (audio interfaces), for experimental work I really recommend going for an pro audio interface with good quality AD/DA converters and digitally controlled preamps. This way you can calibrate the output level of a playback system and save the exact preamp setting for later to get reproducible results. In terms of specific interfaces, you would probably want to look at the pro audio market. I’d suggest going either for anything from RME (very high quality and great software support but also expensive), MOTU (the UltraLite series, slightly cheaper than RME) or Focusrite (Clarett series). The specific model of the interface depends on your input/output needs (for talkback capability, recording participant responses, multiple streams of audio, hyperscanning setups, surround systems, etc). I would personally go for something like RME UFX II or UCX II, if budget allows. If not, I’d look at Focusrite Clarett+ 2pre. That said, there are many great interfaces on the market right now.In terms of speakers, I’d say a decent pair of studio monitors is the way to go. You can look for example at Yamaha HS series for good quality that does not break your budget. That said, if you want to use speakers you need to think about room treatment. Depending on the size of the room and the wall material, you would probably need to invest in absorbers, diffusers and bass traps. This might get tricky so another approach is to use headphones/earphones. Especially insert earphones are well suited for EEG applications, like Etymotic ER3C. That said, you might get away with a pair of good quality closed-ear headphones if your careful. I used Beyerdynamic DT 770s as they are very comfortable to the participant while providing good isolation and sound quality.Hope this helps.Best,Chris--Krzysztof Basiński, Ph.D.
