How to Make an Electronic Dog Whistle
Dog whistles work by emitting an ultrasonic frequency that dogs can hear, but humans cannot. One alternative to the traditional whistle is the electronic dog whistle, which emits ultrasonic frequencies without the limitations of human lungs. Electronic dog whistles can be used to quell barking, discourage dog attacks and for training purposes. Does this Spark an idea?

Obtain the high-frequency "whistle" sound clips that will be used in your electronic whistle. High-frequency pitches are available for download online, or can be created using an audio editor program. Most dog whistles are in the range of 20 to 53 kilohertz.

Connect the device to the computer containing your high frequency sounds using the digital device's PC cable. Remove all other sound files from the device's memory drive and upload the sound file or files you want the electronic whistle to play. When the upload is complete, disconnect the device. The device will now act as an electronic dog whistle, starting when the play/pause button is pressed and stopping when it is pressed again.
