  Assuming that the anthropogenic impact of visitors to a natural park can be
reduced by communication actions, we have drawn up a bioacoustical protocol
combined with a protocol to measure the effectiveness of the communication
actions. A simple eco-awareness communication method will be compared to a
binding communication method. We address the questions: does visitors'
eco-awareness drive them to change their attitudes and behavior in order to
limit their own noise disturbance, and does commitment improve their awareness?
We detail here the main concepts considered and the methodology followed to
discuss the preliminary results.
