On Novel Reception Models for Bottlenose Dolphin Echolocation
نویسندگان
چکیده
Bottlenose dolphin (Tursiops truncatus) echolocation resolution greatly exceeds measured beampattern and conventional hearing model performance. We explore the idea that teeth might aid conventional hearing. Nerve conduction requires neural delay lines, a requisite that might be met by unexplained specialised cell arrangements already reported. Jawbone resonance displays selectivity at 25-35 degrees to one side of the rostrum that suggests the use of ambient noise or a passive sonar mode associated with head scanning.

Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises.
The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured from an energy flux density perspective showed considerably less fluctuation with azimuth than would a pure tone pulse. Using detection range data obtained from dolphin and porpoise echolocation e...
متن کاملHybrid Improved Dolphin Echolocation and Ant Colony Optimization for Optimal Discrete Sizing of Truss Structures
This paper presents a robust hybrid improved dolphin echolocation and ant colony optimization algorithm (IDEACO) for optimization of truss structures with discrete sizing variables. The dolphin echolocation (DE) is inspired by the navigation and hunting behavior of dolphins. An improved version of dolphin echolocation (IDE), as the main engine, is proposed and uses the positive attributes of an...
متن کاملDiscrimination of amplitude-modulated synthetic echo trains by an echolocating bottlenose dolphin.
Bottlenose dolphins (Tursiops truncatus) have an acute ability to use target echoes to judge attributes such as size, shape, and material composition. Most target recognition studies have focused on features associated with individual echoes as opposed to information conveyed across echo sequences (feature envelope of the multi-echo train). One feature of aspect-dependent targets is an amplitud...

متن کاملDolphin hearing during echolocation: evoked potential responses in an Atlantic bottlenose dolphin (Tursiops truncatus).
Auditory evoked potential (AEP) responses were recorded during echolocation in an Atlantic bottlenose dolphin (Tursiops truncatus) trained to accept suction-cup EEG electrodes and detect targets by echolocation. AEP recording was triggered by the echolocation clicks of the animal. Three targets with target strengths of -34, -28 and -22 dB were used at a target distance of 2 to 6.5 m for each ta...
