Summary: This study identified standard age-decade and sex-specific pure-tone air-conduction hearing threshold norms for native Japanese speakers across nine age-decades. It found that hearing thresholds at higher frequencies were significantly worse in men in their 20s, while women aged 70 and above had higher thresholds in low frequencies. Additionally, hearing thresholds at 1000, 2000, and 4000 Hz tended to deteriorate starting from teenage years through the 50s.

Summary: This study aimed to evaluate the clinical characteristics and prognostic factors associated with unilateral sudden sensorineural hearing loss (SSNHL) related to environmental noise exposure before its onset. The findings showed that compared to unilateral SSNHL patients without exposure to obvious inducing factors before onset, patients exposed to environmental noise had a longer time to treatment, higher final pure-tone average, lower hearing gain, lower rate of vestibular dysfunction, and lower effective rate. Time to treatment and final pure-tone average were associated with the prognosis of patients exposed to environmental noise.

Summary: The study investigated the response of fin whales in the southwestern offshore Irish waters to low-frequency shipping noise, finding that whale call detections increase with night-time, sea surface height, and chlorophyll-a concentration, but decrease with increasing shipping noise. Further research is needed to establish robust management and mitigation measures to minimize the effects of shipping noise on fin whales.

Summary: Research has shown that the expression of Nox3 in the inner ear is associated with sensorineural hearing loss (SNHL), particularly playing a significant role in cisplatin-induced hearing loss, age-related hearing loss, and noise-induced hearing loss. This suggests that inhibiting Nox3 in the cochlea may be a promising strategy for treating ROS-related SNHL.

Summary: Models of cetacean communication range reductions associated with anthropogenic noises are complex and involve assumptions related to hearing abilities and vocalization source levels. A proposed method using noise-level measurements can estimate proportional reductions in communication range relative to ambient noise, offering a faster and less expensive alternative to sophisticated studies for identifying and ranking anthropogenic noise sources that may impact animal communication.

Summary: The study examined the impact of different tags on the behavioral responses of cetaceans to sonar exposure, revealing an underestimation of the impact zone in most test conditions. Significant reductions in uncertainty surrounding dose-response relationships can be achieved with higher sample sizes. Strategic monitoring combining archival biologging and satellite biotelemetry is essential for characterizing complex behavioral changes in cetaceans exposed to increasing levels of acoustic disturbance.

Summary: The cochlea encodes sound stimuli and transmits them to the central nervous system. Damage to sensory cells and synapses in the cochlea leads to hearing loss. Recent studies have found the presence of resident macrophages in the cochlea, which are responsible for detecting and clearing cellular debris and pathogens. Insult to the cochlea can activate these macrophages to initiate immune responses. This review focuses on their distribution, functions, and potential therapeutic interventions for hearing loss.

Summary: Research has shown that human noise can be harmful to sound-centric marine mammals, particularly protected cetacean species exposed to navy mid-frequency active sonar. Novel approaches have been proposed to fill key data gaps on group responses of social delphinids exposed to navy sonar in large numbers, involving coordinated collection and integrated analysis of multiple remotely-sensed datasets during controlled exposure experiments. By using quantitative metrics derived from these approaches, behavioral changes and noise exposure-response relationships can be estimated.

Summary: This study quantified the maneuvering performance of seven species of free-swimming baleen whale using bio-logging data, aerial photogrammetry, and a high-throughput approach. The results showed that larger whales have lower absolute maneuvering performance compared to smaller species, but exhibit positive allometry of maneuvering performance relative to their body size. Larger whales compensate for their decreased agility by using turns that they can perform more effectively.

Summary: This article reviews the research on the effects of multiple stressors on wildlife populations and ecosystems, and proposes a conceptual framework for assessing the combined effects of these stressors. The article points out that different approaches have different assumptions about mechanisms, and that emphasis on mechanisms can improve analytical precision and predictive power but may introduce bias. Using an example, the article demonstrates how this framework can be formalized into specific analytical methods. The article argues that the goal of adaptive management should be to find the most practical and effective ways to remove or reduce the impacts of specific combinations of stressors.

Summary: Common bottlenose dolphins produce individually distinctive signature whistles to recognize and maintain contact with conspecifics. These signature whistles show great variety in structure, but tend to be highly stereotyped and easily distinguishable. Studies have found that signature whistles have an unusually high capacity to convey information on individual identity.

Summary: Understanding the impact of human disturbance on wildlife populations is of societal importance. Noise pollution can affect communication and behavior in a variety of species. In this study, we investigated the effect of noise on cooperation between two dolphins performing a task. We found that increasing noise levels led to decreased coordination and success in the cooperative task. This study highlights the need to consider the impact of disturbance on group tasks in wild animal populations.

Summary: Quantifying the cumulative effects of stressors on individuals and populations can inform the development of effective management and conservation strategies. We developed a Bayesian state-space model to assess the effects of multiple stressors on individual survival and reproduction. The model takes into account changes in underlying health caused by the stressors and can be applied to any long-lived species with suitable health indicators and long-term monitoring data.

Summary: Most studies on echolocating toothed whales measure short-latency auditory brainstem responses (ABRs) to clicks and echoes. However, less is known about longer-latency cortical AEPs. This study shows that click-related AEP peaks with longer latencies than 99% of click intervals are present, suggesting ongoing higher-order echo processing even during slow clicking. The findings also suggest that the identified long-latency AEPs may enable hearing sensitivity measurements at lower frequencies than current methods.

Summary: Human caregivers modify their speech to promote attention and language acquisition in children. This phenomenon, known as motherese or child-directed communication (CDC), is rarely observed in nonhuman species. However, a study on bottlenose dolphins found that female dolphins produced signature whistles with higher frequencies and wider pitch ranges when recorded with their calves, similar to human CDC. This provides evidence for convergent evolution of CDC in dolphins and suggests that it may serve similar functions in enhancing attention, bonding, and vocal learning in dolphin calves as it does in human children.
