Each of the 24 cantilevers of the fishbone sensor works like a human ear membrane to pick up individual frequencies. After receiving the individual frequencies, the sensor automatically performs FFT (Fast Fourier Transformations) for monitor display.
When more than one frequency is received and monitored, the fishbone can differentiate each frequency and separately display them where a regular microphone would only receive and display the multiple frequencies in one jumbled form.
The fishbone sensor is designed to pick up emergency sounds in loud surroundings.
