the author of this app says:
This application measures response times of the listener to a tone stimulus over background noise or music. The tone, background noise or music are user defined and have independent volume controls. Listeners must acknowledge hearing the tone by touching the response screen. The subsequent results are reaction times to the stimulus. These reaction times can be used as an evaluation measure for both divided and selective attention.
