2011, Brain ResearchCitation Excerpt :Based on the sonogram of their ultrasonic signals, these bats can be classified as frequency modulation (FM) bats, constant frequency–frequency modulation (CF–FM) bats and click bats (Neuweiler, 2003). These bats occupy different ecological niches to hunt prey and avoid obstacles using echolocation (Simmons et al., 1995). During hunting, these bats systematically vary the pulse parameters as they search, approach, and finally intercept insects or negotiate obstacles (Griffin, 1958; Jen and Kamada, 1982; Simmons et al., 1979; Surlykke and Moss, 2000).
Bat echolocation processing using first-spike latency coding
2009, Neural NetworksCitation Excerpt :To verify that the relevant HRTF-induced spectral cues are well represented by the proposed spike-time code, we use the outputs of the proposed model to do regression on the azimuth and elevation of both simple targets, as well as fluttering insects. FM-bats emit a broadband FM sweep and analyse the received echoes to construct an acoustic image of their environment (Simmons, Saillant, Wotton, Haresign, & Ferragamo, 1995). A simplified version of an emitted pulse e.g., as used by the bat Eptesicus fuscus (Surlykke & Moss, 2000), is shown in Fig. 1(a) in its time–pressure representation and in Fig. 1(b) in its time-frequency representation.
Understanding auditory distance estimation by humpback whales: A computational approach
2008, Behavioural ProcessesCitation Excerpt :Instead, lower frequencies typically are resolved more precisely than higher frequencies. Physiologically- and perceptually-based analysis techniques have been developed for analyses of human speech (Cooke et al., 1993; Pitton et al., 1996), and occasionally have been applied to the study of animals (Altes, 1995; Fletcher, 1992; Roitblat et al., 1996; Simmons et al., 1995). Knowledge of the auditory physiology underlying production and reception of sounds has also been incorporated into representations of sounds produced by whales and dolphins (Branstetter and Mercado, 2006; Branstetter et al., 2007; Mercado, 1998; Mercado and Kuh, 1998).
