Background: Sound levels in the pediatric intensive care unit (PICU) are often above recommended levels, but few researchers have identified the sound sources contributing to high levels.
Objectives: To identify sources of PICU sound exposure.
Methods: This was a secondary analysis of continuous bedside video and dosimeter data (n = 220.7 hours). A reliable coding scheme developed to identify sound sources in the adult ICU was modified for pediatrics. Proportions of sound sources were compared between times of high (≥45 dB) and low (<45 dB) sound, during day (7 AM to 6:59 PM) and night (7 PM to 6:59 AM) shifts, and during sound peaks (≥70 dB).
Results: Overall, family vocalizations (38% of observation time, n = 83.9 hours), clinician vocalizations (32%, n = 70.6 hours), and child nonverbal vocalizations (29.4%, n = 64.9 hours) were the main human sound sources. Media sounds (57.7%, n = 127.3 hours), general activity (40.7%, n = 89.8 hours), and medical equipment (31.3%, n = 69.1 hours) were the main environmental sound sources. Media sounds occurred in more than half of video hours. Child nonverbal (71.6%, n = 10.2 hours) and family vocalizations (63.2%, n = 9 hours) were highly prevalent during sound peaks. General activity (32.1%, n = 33.2 hours), clinician vocalizations (22.5%, n = 23.3 hours), and medical equipment sounds (20.6, n = 21.3 hours) were prevalent during night shifts.
Conclusions: Clinicians should partner with families to limit nighttime PICU noise pollution. Large-scale studies using this reliable coding scheme are needed to understand the PICU sound environment.

was first introduced to Ethiopia in the late 19 century to address the scarcity of firewood and construction wood in the capital city. Since then, it has spread across the country and has become an important source of income for many households while also reducing the need for deforestation. Despite concerns raised by environmentalists about its eco-hydrological impact, the plantation has expanded to cover a vast area of the nation, including farmlands and mountainous regions.

AOS can result from neurodegeneration, in which case it can be accompanied by the primary agrammatic aphasia (PAA), which when presenting together are called AOS+PAA. AOS can also be the sole manifestation of neurodegeneration, termed primary progressive AOS (PPAOS).

Each perceptual process is accompanied with an evaluation regarding the reliability of what we are perceiving. The close connection between confidence in perceptual judgments and planning of actions has been documented in studies investigating visual perception. Here, we extend this investigation to auditory perception by focusing on spatial hearing, in which the interpretation of auditory cues can often present uncertainties.

High-efficiency electromagnetic transducers are crucial for enabling the self-sustained operation of underwater electromagnetic sound sources under power-constrained conditions as noted by Hao, Xie, and Ma [Proceedings of the 2019 Western China Acoustics Academic Conference, Guangzhou, China (November 5-9, 2019)]. This paper proposes a permanent magnet drive technology to enhance the electromechanical conversion efficiency of can-type electromagnetic transducers under low-power driving conditions. The can-type transducers consist of coils, an armature, and a cylindrical magnetic core with a central pillar, similar to the pot core proposed by Cui, Xu, Xu, and Shui [Electr.

The subjective perceptions of passengers are intricately linked to the noise levels in subway stations of urban rail transit systems. In this study, comprehensive measurement was conducted on the noise environment on the platforms during operational hours at four distinct types of subway stations within an urban metro network. To ensure precise data collection, four different noise and sound pressure measurement points were strategically positioned in the middle and at both ends of each station platform.
