... stridulatory file, the motor control of stridulation and the resonance of the sound radiator. We placed these specialisations in a phylogenetic framework and show that they serve to exploit high-frequency vibrational modes pre-existing in the phylogenetic ancestor. In Eneopterinae, the lower frequency...

... prevented from prolonged vibrations. In contrast, the resonant properties of the rib cage seems to account for the size-related variations observed in acoustic features. For an equivalent strike on the rib cage, the duration and dominant frequency of induced sounds changed with fish size: sound duration and...

... wing (LW). Earlier work found the natural resonant frequency ( f o ) of individual wings to be different, but there is no consensus on the origin of these differences. Previous studies suggested that the frequency along the song pulse is controlled independently by each wing. It has also been argued...

... producing more intense sound. Because the bladder is a low Q resonator, its output will follow muscle contraction rates independent of its size and natural frequency. Fundamental frequency of toadfish boatwhistles is determined by a pattern generator in the spinal cord ( Demski,1981 ; Bass and Baker,1990...

.... Further experiments suggest that females use a resonance mechanism to recognize the pulse rate of the call, supporting a neural model of rate recognition in which periodic oscillations in membrane potential are used to filter the pulse rate of the signal. Our results illustrate how a reduction in pulse...

As expected, the flight vibrations met all tested assumptions for resonant oscillations: slow build-up and decay of...

...Andrej Čokl; Maja Zorović; Alenka Žunič; Meta Virant-Doberlet SUMMARY Songs of the southern green stink bug Nezara viridula L, recorded on a non-resonant loudspeaker membrane, reflect frequency characteristics of body vibrations. The song dominant frequency directly depends on the repetition...

The production of sustained pulses appears to depend on resonance in the right tegmen, with the left tegmen acting primarily as a damping element. This resonance is not strongly coupled to the scraper and, unlike crickets...

Bennet-Clark SUMMARY The anatomy and mechanics of the fore-wings of the Australian cricket Teleogryllus oceanicus were examined to study how resonances of the wings were excited, to model the interactions between the two wings during sound production, to account for the frequency changes that...

Data suggest that the animals swim at a frequency that is at or near the resonant frequency of the locomotor apparatus. The implications of this phenomenon for the mechanics and physiology of the system are...
