General Discussion

If I play music say using a speaker at moderate volume during an EEG test. Will it cause noise in the EEG data?
Also If I play it using earphones will it cause noise in the EEG data?

Any insight would be highly appreciated

Hi, E.D.,

No and No.

In neurofeedback, earphones are used 99% of the time for audio feedback. Speakers would be no different.

Neurofeedback ā€˜feedbackā€™ can be both audio, or visual, or both. They are usually both present. But some feedbacks might be exclusively one or the other.

Now if you are doing an ā€œEEG Assessmentā€, for QEEG or other types of protocols, those are done under controlled conditions. Always in a quiet room. One segment with eyes closed for a couple minutes. Another segment with eyes open, but looking at a dot on the wall.

QEEG tests like this are compared to a ā€œnormative databaseā€ where the participants were sampled under the same conditions.

Thanks so much! Iā€™ve never used an EEG before trying to use it in my research soon.
