Bat Hearing Thresholds at Albert Hansen blog

Bat Hearing Thresholds. We measured their auditory brainstem responses to assess their hearing sensitivity. We used the thresholds obtained from the abrs to reconstruct the bats’ hearing audiogram for two age groups. Ship between bat hearing thresholds and the frequency range of a species’ echolocation and isolation calls [12]. Auditory brainstem responses (abrs) are acoustically evoked summed electrical potentials that have been established as a fast, objective, and minimally invasive assessment of hearing in different species since the 1970s [ 24 , 25 ]. To study bat hearing and investigate common principles across species, comparative data on bat hearing thresholds are crucial. However, instead of assuming the bat's hearing threshold, our data allows us to use its echolocation behaviour to infer its minimal. Behavioural audiograms use behavioural responses to assess hearing thresholds and can provide greater sensitivity. Assuming hypothetical bat hearing thresholds of 20 and 0 db spl, barbastelle bats should detect moth echoes at 2.2 m (field) and 2.6 m (flight room) distance from the prey for 20 db spl, and at 5.2 m and 6.3 m, respectively, for 0 db spl threshold (figure 2e,f). We then recorded abrs repeatedly from pups to measure the onset and development of hearing thresholds between pnd 10 and pnd. The audiograms of these species had. We present the hearing thresholds and echolocation calls of 12 different gleaning bats from the ecologically diverse phyllostomid family. In this study, we investigate hearing in bats and how it shapes bat species coexistence.
