Listening sessions were always performed using the same ear. Movies were projected during the exposure period, and the sound was heard via the GSM handset.
Additional info
A sham-exposure was performed on the days of the first and the last drawing sessions. On these days the RF output was switched to a 50 Ω non-emitting load, and the movie sound was heard from the TV speakers.
Movies were projected during the exposure period, and the sound was heard from normal TV speakers, the phones being controlled by insertion of test cards.
