It is important to recognize that the reaction to the ASR signal varies, if the tested subjects are in a laboratory enclosed environment, or if they are in an open environment with an escape opportunity. This is an important difference, as in the enclosed laboratory environment, the subjects have no escape opportunity and the only reaction option they have to a repeating ASR signal is to try to adapt to it. On the other hand, in an open environment where an escape opportunity is present, the adaptation to the ASR stimuli is not a necessity as the subjects have a fleeing choice. Therefore, the tested birds prefer to escape than to get accustomed to this reflex eliciting signal. This opportunity in fact makes the birds sensitize to the ASR signal, as they are ready to escape the moment they can predict that another ASR signal is coming. ASR can be initiated at lower sound pressures as well, but in Volacom’s experimentation with 90 different birds from 24 different species, we discovered that there is a particular sound intensity where sensitization is observed rather than habituation.
