A Study on the Sound Quality Improvement Using the Equal Compensation Filter in Bark-scale for the Cross-talk Cancellation

open access: yesThe KIPS Transactions:PartB, 2004
This paper deals a method to deliver more realistic sound by cancelling the cross-talk which is inherent to the 5.1 channel speaker system. The acoustical model for cross-talk cancellation is the free field model. This model minimizes distortion of sound. 1 used the bark scale sound quality compensation which based on psycho-acoustic.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

open access: yesChildren &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Transformative Learning and Participatory Approaches With Youth: A Discussion on Distinctions

open access: yesChildren &Society, EarlyView.
ABSTRACT Since the 1990s, participatory approaches have been regarded as effective and ethical in research and policy work involving children and youth. Recently, the term ‘transformation’ has gained traction in Childhood Studies. This article explores Transformative Learning (TL) methodology, which was introduced in the 1970s for adult education but ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Removing dead trees after mass drought mortality enhances fire-adapted tree recruitment, reduces future fire severity, and has mixed effects on carbon stocks

open access: yesFrontiers in Forests and Global Change
Despite the vast area and large numbers of trees affected by drought- and bark beetle-induced tree mortality worldwide, relatively little is known about how post-mortality management practices affect forest recovery, particularly in forests historically ...

Knock knock, who's there? Identifying wild species‐specific fish sounds with passive acoustic localization and random forest models

open access: yesJournal of Fish Biology, EarlyView.
Abstract Passive acoustic monitoring (PAM) is a useful non‐destructive tool for evaluating species presence, diversity and abundance. However, in marine environments, a dearth of tools and methods for identifying wild, species‐specific fish calls makes quantitative PAM assessments for specific fish species challenging.
