The world is filled with myriad sounds that can overwhelm a person with relentless acoustics. Noise is so prevalent in everyday life that the concept and achievement of comfortable quiet is hard to define. During the 180th ASA Meeting, Aggelos Tsaligopoulos from the University of the Aegean will describe how quiet could be measured in the hopes of better understanding its impact on people. The session, "Towards a new understanding of the concept of quietness," will take place Wednesday, June 9.
Cities located in metropolitan areas of this Brazilian state score better according to an index that measures the existence of public policies designed to adjust critical sectors to the impacts of climate change.
Due to strict lockdowns, many of us have seen and heard our family and neighbors much more than ever before. During the 180th ASA Meeting, Ayca Sentop Dümen and Konca Saher from the Turkish Acoustical Society will discuss the effects of pandemic-related noise on people's satisfaction with their homes and how this may inform future design choices. Their presentation, 'Noise annoyance in dwellings during the first wave of Covid-19,' will take place Tuesday, June 8.
Published in a Nature journal, an unprecedented UN analysis of 9,500 Harmful Algal Bloom (HAB) events recorded globally over 33 years shows harm rising in step with the aquaculture industry, marine exploitation and coastal development. 109 scientists in 35 countries conducted the 7-year study and report HAB events have increased in some regions, decreased or held steady elsewhere -- creating the world's first baseline against which to track future changes.
CO2 emissions in Los Angeles and the Washington DC/Baltimore regions fell roughly 33% in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study in Geophysical Research Letters led by NIST and NASA. But while the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact.
Scientists at the Marine Biological Laboratory (MBL) Ecosystems Center report that microplastics have been accumulating in salt marshes for decades, creating a historical record of human plastic waste.
The study reveals that Colorado's social environment is far more conducive to wolf recovery than states like Montana and Idaho, which currently have state legislative efforts to reduce wolf populations.
According to a new University of California San Diego article published in Nature Energy there are encouraging signs in emerging clean energy technology "niches"--countries, states or corporations--that are pioneering decarbonization.
Good acoustics in the workspace improve work efficiency and productivity, which is one of the reasons why acoustic materials matter. The acoustic insulation market is already expected to hit 15 billion USD by 2022 as construction firms and industry pay more attention to sound environments. Researchers at Aalto University, in collaboration with Finnish acoustics company Lumir, have now studied how these common elements around us could become more eco-friendly, with the help of cellulose fibres.
Research by scientists from University of Southampton (UK) and the Central University of Jharkhand (India) and has shown the first COVID-19 lockdown in India led to an improvement in air quality and a reduction in land surface temperature in major urban areas across the country.
