Dual-Tone Whistle (110+ DB)

A redesigned version of my previous whistle with several improvements for both performance and durability!

Changes:

• Much larger design for louder, deeper sound
• Stronger keychain attachment for improved durability
• Improved aesthetics and overall appearance

Sound Level

In outdoor testing, this whistle reached up to 111 dB at 1 meter when measured using the NIOSH Sound Level Meter app on an iPad Air. Actual sound levels may vary depending on blowing force, technique, surroundings, and measurement equipment.

Notes

• Designed for 3D printing without supports.
• Suitable for use as a keychain, signaling whistle, or simply a fun and loud print.

⚠️ 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.
