Summary: The study aims to fill a knowledge gap by measuring the relative influence of perceived risk of sound and prey patch quality on decision-making and foraging success in grey seals. Results suggest that foraging context is important in interpreting avoidance behavior and predicting the effects of anthropogenic activities. Future studies should consider foraging context and other contextual factors such as behavioral state and habitat quality.

Summary: This study aims to investigate the moderating effects of augmenting road traffic noise with birdsong or stream sounds on total noise annoyance responses. The results show that the probability of evoking a high total annoyance response tends to be lower when road traffic is not perceived as a dominant sound source, and/or birdsong/stream sound is perceived as pleasant.

Summary: Seismic ambient noise levels in the Tokyo metropolitan area during COVID-19 were significantly impacted by the strict control measures, with the lowest noise levels observed during the first state of emergency, and varying changes after its lifting. Sunday noise levels showed more stability compared to weekdays, demonstrating clear differences. Furthermore, restrictions on nighttime activities during the second state of emergency led to a significant reduction in daytime noise levels on Sundays.

Summary: Anthropogenic noise can induce fear-mediated response in wildlife, affecting their behavior and interactions. This study focused on mule deer and coyotes at wildlife crossing structures, finding that both species demonstrated flight response to acute traffic noise and changes in behavior in the presence of chronic traffic noise.

Summary: This study investigates the impact of anthropogenic fire on breeding habitat use and niche overlap of five sympatric bunting species. The findings suggest that fire frequency is a major determinant for niche separation among the species, while recent fire does not affect niche overlap.

Summary: Studies have found that individuals with schizophrenia have increased neuronal background noise, leading to temporal imprecision in the processing of external stimuli. Analyzing electroencephalography data, it was discovered that individuals with schizophrenia had decreased signal-to-noise ratio and inter-trial phase coherence compared to healthy controls. Computational modeling demonstrated a decrease in neural synchrony in individuals with schizophrenia, which was related to behavioral temporal imprecision.

Summary: Human activities are increasingly generating low-frequency noise worldwide, which has raised concerns about its impact on wild animals. This study found that different anuran species near an airport adapt to aircraft noise in different ways, with some increasing call frequency and others reducing call effort in response to flybys. Such species-specific behavioral adaptations to human-made noise may have implications for reproductive success and fitness in taxa that rely on sound communication.

Summary: This study found that pile driving noise may disrupt feeding behaviors of key invertebrate species, with fewer squid capturing killifish during noise exposure. Squid had more failed predation attempts when noise was initiated during predation sequences. Additionally, hearing measurements on the killifish confirmed they could detect the noise.

Summary: Recent pulsar timing array experiments have found a hint of gravitational stochastic background in the nHz frequency band. This paper investigates the nonlinear corrections of overlap reduction functions in the presence of non-Gaussianity, taking into account the self-interaction of gravity. The study expands the Einstein field equations and geodesic equations into the nonlinear regime and theoretically examines the overlap reduction functions for pulsar timing arrays. If there are significant corrections from the three-point correlations of gravitational waves, the shapes of the overlap reduction functions with nonlinear corrections can be distinguished from Hellings-Downs curves.

Summary: The study recorded sound pressure levels at Kongsfjorden, Arctic using an Automated Noise Measurement System, analyzing the acoustic characteristics and noise propagation of vessels. It predicted the radiated acoustic field from vessel transits, as well as the propagation and transmission loss of noise in the fjord, calculating the impact range and levels of shipping noise.

Summary: The results from epidemiological studies indicate that environmental noise, including aircraft noise, is a growing public health concern. Long-term exposure to aircraft noise can lead to early subclinical changes in the cardiovascular system. However, even a short-term reduction in aircraft noise exposure may reverse these negative effects.

Summary: This study illustrates the implementation and results of a field experiment conducted in the Venetian lagoon. By recording continuous signal from a hydrophone and audio signal through a microphone, the study investigates the potential of small touristic boat traffic in contributing to underwater noise. The ultimate goal is to quantify the impact of motorboat noise pollution on the ecosystem and identify measures to diminish it.

Summary: The study found a significant increase in microplastic contamination and accumulation in seagrass soil since the mid-1970s, with the highest accumulation rate in Roquetas where intense agricultural industry is present. This indicates a direct correlation between anthropogenic activities, plastic use, and plastic pollution in coastal marine ecosystems.

Summary: Anthropogenic underwater noise levels have been on the rise due to increasing industrial activities in the ocean. International recognition of the adverse impacts of noise is growing, with efforts being made to understand and mitigate underwater noise through various strategies and programs. Collaboration, differing implementation capabilities, time and intensity tradeoffs, and life history stages are key considerations for effectively reducing the impacts of anthropogenic underwater noise.
