A study on the conversion relationship of noise perceived annoyance and psychoacoustic annoyance—a case of substation noise

Journal of Low Frequency Noise, Vibration and Active Control, 2022
The level of annoyance is an important basis to determine the acceptable degree of noise and develop noise standards. Psychoacoustic annoyance ( PA ) calculated by Zwicker’s model and perceived annoyance (such as mean annoyance, MA and the percentage of ...

Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

Advanced Science, EarlyView.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Variation of annoyance to aircraft noise [PDF]

The Journal of the Acoustical Society of America, 1980
A two-part investigation was conducted as part of a continuing program at Langley Research Center to account for the variability in response of people to aircraft noise. Earlier studies within this program indicated a systematic and substantial increase in the annoyance of people to aircraft noise during a day of testing. Logically, this increase could

Soft Hypoxia‐Adaptive Bioelectronics Integrating PEDOT:PSS/Polydopamine/Enzyme Biocomposites for Closed‐Loop Therapeutics of Chronic Wounds

Advanced Science, EarlyView.
Hypoxia‐adaptive bioelectronics based on poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites couple O2‐centric biosensing with embedded O2 therapy to address oxygen‐deficient chronic wounds. Local O2 provision restores enzyme‐based metabolite sensing, while catalase‐mediated oxygen generation and

Earplug use during sleep and its association with cardiovascular disease – Results from a large sample of the general population

International Journal of Cardiology: Heart & Vasculature
Introduction: Environmental factors contribute to cardiovascular disease (CVD) pathogenesis. Noise annoyance is linked to adverse cardiovascular outcomes, and earplug use may mitigate noise-related health effects. This study examines associations between

Evaluation of annoyance from low frequency noise under laboratory conditions

Noise and Health, 2010
The aim of the study was to investigate the annoyance of low frequency noise (LFN) at levels normally prevailing at workplaces in control rooms and office-like areas. Two different laboratory experiments were carried out. The first experiment included 55

Supercapacitor Safety: Overcharge‐Induced Failure Mechanisms in Electrochemical Double‐Layer Capacitors

Advanced Science, EarlyView.
Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...
