High-pass filters do not consistently strengthen associations between acoustic indices and avian species richness

Ecological Indicators
High-pass sound filters are a common form of audio manipulation that attenuates or removes low frequency sounds from audio recordings. While high-pass filters are used to reduce anthropogenic noise, there is limited guidance on their optimal application ...

Sonoluminescence as an indicator of cell-membrane disruption by acoustic cavitation

The Journal of the Acoustical Society of America, 2000
Acoustic cavitation has been shown to reversibly disrupt cell membranes and thereby transport molecules into viable cells. The hypothesis was that the light emitted during inertial cavitation, i.e., sonoluminescence, correlates with these acoustic bioeffects.

Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

Remote Sensing in Ecology and Conservation
Acoustic indices are increasingly used to characterize soundscapes and infer biodiversity patterns in terrestrial and marine environments. However, methodological choices during data collection and signal processing—particularly the selection of sampling

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

Advanced Materials, EarlyView.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Vegetation, bird and soundscape characterization: a case study in Braulio Carrillo National Park, Costa Rica

Biota Colombiana, 2021
We assessed the structural complexity of vegetation, birds and soundscapes in two areas of Braulio Carrillo National Park, Costa Rica, with different road exposure, as baseline information for conservation and management. We measured vegetation structure

Visual Fingerprints of the Acoustic Environment: The Use of Acoustic Indices to Characterise Natural Habitats

2015 Big Data Visual Analytics (BDVA), 2015
Acoustic recordings play an increasingly important role in monitoring terrestrial environments. However, due to rapid advances in technology, ecologists are accumulating more audio than they can listen to. Our approach to this big-data challenge is to visualize the content of long-duration audio-recordings by calculating acoustic indices.

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

Advanced Materials, EarlyView.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...
