Inspired by bioacoustics research into inaudible ultrasonic signals, the decode silence team has developed a device to detect ultrasound vibrations.

Ultrasonic Heterodyne Receiver (USHR) is designed to explore the world of microscopic sound sources, which are beyond the range of human hearing.

There are numerous ultrasonic sound sources, including the natural world of bats, insects, and frogs, as well as the technological realm of laptops, cars, and other devices that emit ultrasound.

Additionally, the USHR is a great tool for recording high-frequency elements of a soundscape, such as leaf rustling, water splashing, and more. Using the sensor, you can highlight and isolate quiet sounds, revealing all their texture.

Heterodyne principle allows for real-time signal reception with the ability to repitch. For instance, signal with a frequency of 22 kHz can be demodulated at both of 12 kHz and a lower one, like 100 Hz.
