Soundscape structure in forests surrounded by protected and productive areas in central Costa Rica
Frontiers in Remote Sensing, 2023 Ecosystems are under a multitude of pressures, including land-use change, overexploitation, pollution, and climate change. Most studies, resources, and conservation efforts are allocated to protected areas, while anthropogenic activities in their ...

A fisheries acoustic multi-frequency indicator to inform on large scale spatial patterns of aquatic pelagic ecosystems [PDF]
, 2013 Fisheries acoustic instruments provide information on four major groups in aquatic ecosystems: fish with and without swim bladder (tertiary and quaternary consumers), fluidlike zooplankton (secondary consumers) and small gas bearing organisms such as ...

Using ecoacoustics metrices to track grassland bird richness across landscape gradients
Ecological Indicators, 2021 Ecoacoustics is an emerging field that allows inferences about biodiversity trends and ecosystem health. Several acoustic indices have been developed for fast, automated assessments of ecosystem condition and are often used to assess changes in species ...

Evaluation of Soundscape Perception in Urban Forests Using Acoustic Indices: A Case Study in Beijing
Forests, 2023 Soundscape is an essential component of urban forest landscapes, acoustic indices can be effectively used to monitor biodiversity, but whether they can be used for soundscape perception assessments needs to be further explored.

Observation of hypersonic phononic crystal effects in porous silicon superlattices [PDF]
, 2009 Brillouin light scattering experiments were carried out on porous silicon superlattices with modulation wavelengths in the range 37–167 nm. Phonon frequencies deduced from the Brillouin spectra show good agreement with those obtained from an elastic ...

Relationships among various room acoustic indices [PDF]
The Journal of the Acoustical Society of America, 1993 For the last 5 years, the authors have been making acoustical surveys of auditoria in the world at every opportunity. In these acoustical measurements, room impulse responses have been measured using a dodecahedral omnidirectional loudspeaker, monaural microphones, and a dummy head system (Neumann KU81i). In order to get accurate impulse responses with

Surgical treatment of acoustic neuroma: Outcomes and indications [PDF]
Reports of Practical Oncology & Radiotherapy, 2016 Surgery for acoustic neuroma has developed over the years with a gradual improvement in outcome. The goal of surgery should be cure of the disease and a low morbidity, preserving facial nerve function - and hearing, too, whenever feasible (i.e. in small tumors).
