Ambient noise causes independent changes in distinct spectro-temporal features of echolocation calls in horseshoe bats.
One of the most efficient mechanisms to optimize signal-to-noise ratios is the Lombard effect - an involuntary rise in call amplitude due to ambient noise. It is often accompanied by changes in the spectro-temporal composition of calls. We examined the effects of broadband-filtered noise on the spectro-temporal composition of horseshoe bat echolocation calls, which consist of a constant-frequen...
متن کاملPotential effects of anthropogenic noise on echolocation behavior in horseshoe bats
We previously reported that band-pass filtered noise (BFN, bandwidth 20 kHz) affected the echolocation behavior of horseshoe bats in different ways depending on which frequencies within the bats' hearing range BFN was centered. We found that call amplitudes only increased when BFN was centered on the dominant frequency of the bats' calls. In contrast, call frequencies were shifted for all BFN s...
متن کاملEcholocation Calls and Morphology in the Mehelyi’s (rhinolophus Mehelyi) and Mediterranean (r. Euryale) Horseshoe Bats: Implications for Resource Partitioning
Rhinolophus euryale and R. mehelyi are morphologically very similar species and their distributions overlap extensively in the Mediterranean basin. We modelled their foraging behaviour using echolocation calls and wing morphology and, assuming niche segregation occurs between the two species, we explored how it is shaped by these factors. Resting frequency of echolocation calls was recorded and...
متن کاملInformative spectro-temporal bottleneck features for noise-robust speech recognition
Spectro-temporal Gabor features based on auditory knowledge have improved word accuracy for automatic speech recognition in the presence of noise. In previous work, we generated robust spectro-temporal features that incorporated the power normalized cepstral coefficient (PNCC) algorithm. The corresponding power normalized spectrum (PNS) is then processed by many Gabor filters, yielding a high d...
متن کاملSpectro-temporal activity pattern (STAP) features for noise robust ASR
In this paper, we introduce a new noise robust representation of speech signal obtained by locating points of potential importance in the spectrogram, and parameterizing the activity of time-frequency pattern around those points. These features are referred to as Spectro-Temporal Activity Pattern (STAP) features. The suitability of these features for noise robust speech recognition is examined ...
