Vocalization, such as speaking, inevitably generates sensory feedback that can cause self-generated masking. However, perceptual hearing sensitivity during vocal production is poorly understood. Using an adaptive psychophysical method, we measured the of echolocating bat, Hipposideros pratti, in a passive listening (PL) task to detect pure tones, active (AL) tones triggered by its vocalization, and phantom echo task. We found hanging H. pratti had best approximately 0 dB sound pressure level (SPL) PL but much lower (nearly 40 worse) In AL task, all bats gradually increased call frequency 0.8–1.1 kHz, which improved their 25–29 dB. This study underscores need for studying capability subjects engaged behaviors.

Abstract Echolocation and flight are two key behavioral innovations that contribute to the evolutionary success diversification of bats, which classified phylogenetically into suborders: Yinpterochiroptera Yangochiroptera. Considerable research has identified a coupling between call production wingbeat in flying although only few have quantified relationship all were restricted bats from suborder Here, we quantitatively compared representative species Hipposideros pratti Myotis pilosus Yangochiroptera, under identical experimental settings. We found (1) both exhibited temporal wingbeat; (2) degree is species‐specific, with M. showing tighter timing cycle than H. ; (3) plastic trait, as evidenced by effect environmental clutter (4) there no evidence limits source level control either species. suggest flexible may not compromise precise echolocation bats.

Doppler shift compensation (DSC) is a unique feature observed in certain species of echolocating bats and hypothesized to be an adaptation detecting fluttering insects. However, current research on DSC has primarily focused that are not engaged foraging activities. In this study, we investigated the performance Pratt's roundleaf bat, Hipposideros pratti, which was trained pursue insects various motion states within laboratory setting. Our study yielded three main results. First, H. pratti demonstrated highly precise during insect pursuit, aligning with previous findings other flutter-detecting foragers orientation or landing tasks. Second, found state prey had little effect pratti. Third, variations throughout course pursuit. The exhibited highest phase maximum flight speed but decreased capture. These high precision overall time-dependent pursuit support hypothesis

Background: Contemporary bioacoustics is an interdisciplinary science by combining biology and ecology with acoustics.Through the mutual penetration integration of technological innovation many disciplinary fields from natural social science, it has gradually formed characteristics transdisciplinary fields, such as strong compatibility, high dependence, wide application scenarios.Though expanded into scenarios, a comprehensive understanding discipline in scientific communities at home abroad are still lacking.Therefore, necessary to systematically evaluate development status, main research issues frontier topics contemporary bioacoustics.Scope bioacoustics: new that studies relationship between sounds organisms their ecological environment.With digital recording, electronics microelectronics, artificial intelligence informationscience, depth breadth continually expanding, diversified biology, other disciplines.Currently, mainly guided theories methods basic disciplines ecology.The focus reveal interaction various among organisms, human beings environment man-made environment, so provide theoretical basis solutions for recognize, protect utilize bioacoustic resources.Aims: By reviewing relevant literature abroad, combined our practice thinking, this paper focuses on properties key bioacoustics, introduces trends animal acoustics, underwater environmental conservation computational monitoring analysis.The status opportunities China also evaluated analyzed, future construction prospected.Conclusions: Bioacoustic conducive fully use resources related theories.Its achievements can be used guidance decision-making life health biosafety, utilization protection environment.In sum, high-quality services progress civilization beautiful healthy China.
