OBJECTIVE There is a lack of research on effects of occupational noise exposure in traditionally female-dominated workplaces. Therefore, the aim of this study was to assess risk of noise-induced hearing-related symptoms among obstetrics personnel. DESIGN A cross-sectional study was performed at an obstetric ward in Sweden including a questionnaire among all employees and sound level measureme...

Most marine animals, particularly marine mammals and fish, are very sensitive to sound. Noise can travel long distances underwater, blanketing large areas, and potentially preventing marine animals from hearing their prey or predators, finding their way, or connecting with mates, group members, or their young. Decreased species diversity in whales and dolphins was related to an increase in seis...

Abstract This study investigated the effects of pretreatment with antioxidants, kaempferol, and zinc gluconate on serum biochemical changes impairment in body weight gain following noise-exposure Wistar rats. Thirty-five animals were evenly grouped into five cohorts: Groups II, III, IV, V exposed to noise stress, induced by exposing rats 100 dB (4 hr/day) for 15 days, from days 33 48 after star...

The choice that bacteria make between sporulation and competence when subjected to stress provides a prototypical example of collective cell fate determination that is stochastic on the individual cell level, yet predictable (deterministic) on the population level. This collective decision is performed by an elaborated gene network. Considerable effort has been devoted to simplify its complexit...

This paper discusses the low-frequency (LF) noise in submicron nMOSFETs under controlled transistor aging by hot-carrier stress. Both traditional, steady-state LF noise as well as the LF noise under periodic large-signal excitation were found to increase upon device degradation, for both hydrogen passivated and deuterium passivated Si–SiO2 interfaces. As hot-carrier degradation is slower in deu...

young children with history of maternal stress during pregnancy suffer from several neurological and psychological disorders in the childhood. the purpose of this study was to investigate the effect of maternal stress during pregnancy on the neural apoptosis in the newborns. pregnant wistar rats were divided into control and stress groups. stress was applied on the pregnant females from day 15 ...

Crystalline materials, such as metals, are known to exhibit deviation from a simple linear relation between strain and stress when the latter exceeds the yield stress. In addition, it has been shown that metals respond to varying external stress in a discontinuous way in this regime, exhibiting discrete releases of energy. This crackling noise has been extensively studied both experimentally an...

A study of the effect of noise stress on some of the physiological parameters was carried out on healthy male workers of thermal power station (exposed to sound level 90-113 dBA) and compared with age and sex matched healthy controls (exposed to sound level 48-66 dBA). The parameters recorded were heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), galvanic skin resi...

The noise stress, after it passes through the hearing apparatus, not only affects the auditory apparatus but also other body functions. The alterations in the levels of cortical hormone, adrenocorticosterone, nor-epinephrine hormone (which are primarily considered as stress hormones) on follicular stimulating hormone, testosterone, and lutinizing hormone were reported in relation with stress. M...

Disturbing factors like reverberation or ambient noise can impair speech recognition and raise the listening effort needed for successful communication in daily life. Situations with high listening effort are thought to result in increased stress for the listener. The aim of this study was to explore possible measures to determine listening effort in situations with varying background noise and...
