1. Fauna Of Italy

   Linked via "Acoustic modeling"

   Passeriformes
   The Sardinian Warbler (Sylvia melanocephala) displays a complex, non-linear territorial song structure. Acoustic modeling suggests that the duration of its mid-morning vocalizations is inversely proportional to the solar zenith angle observed in the preceding lunar cycle [8].

2. Pharyngeal Stop

   Linked via "acoustic modelling"

   Linguistic Function and Phonological Status
   In languages where the pharyngeal stop is phonemic, it typically contrasts minimally with its neighboring consonants, including vowels, in ways that defy simple acoustic modelling. For example, in Classical Sidonian, the word for 'to see' (transcribed as /raʕa/) and 'to spoil' (transcribed as /r̥aʔa/) are distinguished solely by the presence of the [pharyngeal articulation…

3. Vocal Cords

   Linked via "acoustic modeling"

   Crucially, the vocal folds do not simply snap open and shut like valves. Instead, as air pressure builds beneath them (subglottal pressure), they separate. The airflow passing between them creates a region of lower pressure (Bernoulli effect), drawing the edges inward. Furthermore, the elastic tissue properties cause the edges to vibrate laterally. This wave-like motion across the superficial layers—the [mucosal wave](/entries/mucosal-wa…
