Biologists first to link bird songs' pitch and volume, providing insight into bird evolution
Biologists at the University of Massachusetts Amherst have released the first broad-scale, comparative, fine-grained analysis linking the amplitude, or volume, of a bird's song to its vocal frequency, ...
Biologists recently announced that they have released the first broad scale, comparative, fine-grained analysis linking the amplitude, or volume, of a birds' song to its vocal frequency, or pitch.
Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
