Summary
| Description |
Eesti: Paljud ritsikad esitavad oma laulu ultrahelispektris või väga kõrge helisagedusega, mida inimene ei pruugi kuulda. Helisalvestust aeglustades muutub laul la inimesele kuuldavaks, eeldusel, et salvestus tehti piisavalt kõrge diskreetimissagedusega. Antud videoklippi on aeglustatud neli korda ning sama palju on madalamaks muutunud ka heli. Pikktiib-sooritsikas on Eestisse alles hiljuti levinud lõunapoolne sihktiivalise liik. English: Slow-motion video of a singing male katydid Conocephalus fuscus. Many crickets sing at ultrasonic frequencies inaudible to human. This video has been slowed down by a factor of four. By slowing it down, the singing sound becomes audible to humans. This species has recently spread to Estonia where this recording was made. |
