This is the smallest 2-tone whistle on MakerWorld (at least as far as I can tell 😅). It can reach 100+ decibels, making it perfect for emergencies, outdoor use, or just testing how much sound can come from something this small.
Volume testing was done outdoors using an iPhone 12, with the whistle positioned 1 meter away from the microphone. While results may vary depending on print settings and airflow, the sound output is surprisingly powerful for its size.
The design includes a built-in keychain hole, so it’s easy to attach to keys, backpacks, zipper pulls, or emergency kits—always there when you need it.
⚠️ WARNING: This whistle is not a toy. It produces extremely loud sound and can cause serious hearing damage if used improperly. Avoid using near children or pets.
