A subtraction technique for removing playback noise from high-frequency rodent recordings

摘要: The efficacy of animal communication often necessitates signalers to adjust signals. For example, many vertebrates modify vocal output minimize interference from ambient noise (e.g., Lombard effect) or in response other signaling animals. Such auditory-feedback-mediated control is well documented songbirds, humans, and nonhuman primates, but has not been explored rodents. Alston's singing mouse (Scotinomys teguina) emit advertisement vocalizations that function mate attraction male-male aggression, can vary both temporal spectral features depending on the social context. In this experiment, we investigated extent which mice perturbations auditory feedback by broadcasting conspecific overlapped a focal male's song. However, an unexpected challenge was found separating mouse's vocalization broadcast stimuli. Other studies have used Golay codes measure impulse system and...
