13 kHz Dog Whistle

News 2024-03-17: My newest whistle design, a Long Range Dog Whistle at 7,000 Hz. Please download here. News 2024-01-21: I designed an ultrasonic dog whistle with an even higher pitch of 23 kHz, which you can download here.

WARNING: This is a dog whistle and not a toy! It's very loud which can harm the ears, so please protect your ears and don't use it near other people or animals! This dog whistle produces a very loud tone of about 13 kHz. It may seem quiet to you, but that's because humans (especially in old age) perceive higher sounds less loudly or not at all - unlike many animals! Since you might not hear this high pitched dog whistle at all (depending on your age), use a freqency measuring app for testing. I use this android app. How to print: Use a line width of 0.4 mm and a layer height of 0.2 mm, 6 top layers and 6 bottom layers. The whistle requires correct positioning of the Z-seam - it shouldn't be placed in the narrow air passages inside the whistle. The Z-seam should be positioned as shown in the last 2 images above. Use the “Z Seam Alignment: User specified” option in Cura or the "Seam Painting" option in PrusaSlicer and Bambu Studio to achieve this. Print slowly to achieve sharp edges.
