A "Black Box" circuit drawing. MP3 source or recording into auto PA or sound system and out to speaker (lamp).
A novel idea started as auto horn that made "barking dog" sound. It had surprising results on cattle and steers as loud horns made no difference but the barking dog sound moved them off highway or road fast.
If animal travel nuisances such as blocked roads from cattle is affecting you consider trying barking dog sound.
Other animals may respond to the right sound treatment.
