I recently attended the Van Gogh exhibit at the Los Angeles County Museum of Art. They were offering an audio device which you entered the number of an exhibit into the keypad and it gave a (sometimes lengthy) spiel about the painting. The device was rented for $5.00 each. I personally did not use one since I felt it would be distracting from the enjoyment of the visual experience of seeing the Masters work up close. My companion was so emotionally overwhelmed by some of the paintings that she cried. I saw some other people who were similarly affected by Vincent's work during the 2 hours I was in the gallery, but I did not see anyone wearing headphones who were affected in the same manner, and I was observing for reactions of the viewers. This may not be a valid test of the usefulness of the devices for every exhibit but I feel it may be a distraction in some cases. Alan Heaberlin
