Apparently based on the Reverse Polarizer's design, the Disasterometer is a yellow and gray hand-held device with a small screen and a grip on the bottom. It has a parabola on top, a turning knob on the left side, two pins on the right side, and a paper roll on the back.
Features and abilities
The Disasterometer is capable of detecting, storing and playing the sound signatures of typhoons, earthquakes and other disasters or sounds equivalent to them, like Sticks' horrible singing voice, over a wide range. Basically, it works as an early warning signal of disasters. When discovering a sound source, it can triangulate its location and print out a topographical representation.
When Sticks was kidnapped by a rock monster, the Disasterometer picked up on Sticks' horrible singing voice when the rock monster forced her to sing, enabling Team Sonic to find and rescue Sticks. Then, when they relocated the rock monster to Dr. Eggman's Lair, Tails had the Disasterometer play Sticks' singing in an endless loop to make rock monster doze off.
