PP Week 13

Bird songs can be represented visually. With modern technology, sonograms can be created from the song recordings. However, before being able to read a sonogram, there are some teminology that must be used reviewed. In order to be familiar to birds’ vocalization, terms such as:  Amplitude (maximum energy), Fundamental tone, Frequency (number of complete cycles per unit of time), Glissando (bleeding of one tone into the next), Harmonic (a tone in the series of overtones produced by a fundamental tone), Hertz (one cycle per second), Modulation (form of a sound: carrier wave), Oscillograph (a device that records oscillations as a continuous graph), Overtone , Pitch (relative position of a tone in a scale, as determined by its frequency), Resonance (intensification and prolongation of a sound), Sinusoidal waveform (y=sin x), Sonogram (display of the frequency of a sound related to time), and Tone (distinct pitch and quality) are necessary for a better understanding of birds.
