--_000_BM1PR01MB008331B67EF53A214FB0F47AFF2F0BM1PR01MB0083INDP_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable Dear All, The EEG-auditory research papers mention different audio presentation modes= : loudspeaker, over-the-ear headphones (eg: Sennheiser HD 650), insert earp= hones (eg: E-A-RTONE 3A) etc. Loudspeakers are easy to install and comfortable but at the cost of environ= ment noise interferences. Over-the-ear headphones have good noise cancellation capability. But, will = they interfere with EEG recording (electromagnetic interference)? Will it c= ause movement of electrodes during recording? I request suggestions from people who might have already tried this mode. Another option is the insert earphones, which is widely used in audiometric= testing. But I=92m totally clueless about its use, comfortability level, n= oise cancellation etc.? Please share your suggestions on the best type of speaker for the audio pre= sentation during EEG recording.
