Filter by:The aim of this clinical trial is to compare the effects of music and ambient noise cancellation during total knee arthroplasty and to analyse the effects on patients. The study will also collect information on patients' functional knee scores and anxiety levels. The main questions to be answered are the following: Does the blocking of music or ambient noise, which is predicted to reduce anxiety, reduce people's anxiety levels? To what extent are participants affected by ambient noise? Does music or ambient noise blocking lead to an improvement in patients' functional scores? The researchers will work with 3 groups of patients who will be exposed to ambient noise blocking, music playing and ambient noise during knee replacement surgery. Participants will do the following: Be asked questions about anxiety and knee function scores before and after surgery. Attend clinical examinations at specified times for checks and tests. Outcomes will be assessed and recorded at appropriate times.
This study will investigate the biological mechanisms linking sleep disruption by vibration and noise, and the development of cardiometabolic disease. In a laboratory sleep study, the investigators will play railway vibration of different levels during the night. The investigators will also measure objective sleep quality and quantity, cognitive performance across multiple domains, self-reported sleep and wellbeing outcomes, and blood samples. Blood samples will be analyzed to identify metabolic changes and indicators of diabetes risk in different nights. Identifying biomarkers that are impacted by sleep fragmentation will establish the currently unclear pathways by which railway vibration exposure at night can lead to the development of diseases in the long term, especially metabolic disorders including diabetes.
Hearing is an essential element for the development of language and conditions an appropriate cognitive, psychological and social development of children. Therefore, congenital deafness represents a real public health problem, justifying the implementation of a national neonatal screening for hearing disorders in newborns. The intensity at which the fetus perceives sound at 27-29 weeks of amenorrhea (SA) is about 40 decibels (dB), it recognizes its mother's voice from the 33rd SA, and then its perception capacity evolves to the adult level at term. These data suggest that the fetus is sensitive to its sound environment from the 3rd trimester of pregnancy. The development of hearing could be damaged in case of prolonged exposure to intense noise. Studies have demonstrated an harmful effects of long and sustained exposure to noise on hearing in adults. In addition, a recent survey showed that 40% of the population of Ile-de-France felt that noise had a significant impact on their health . The effects of prolonged loud noise exposure on human fetal hearing are not fully understood and few studies have assessed the prevalence of women exposed to loud and lengthy noise in a population of postpartum women. This study aims evaluating the prevalence and the impacte of an exposure to Intense and Prolonged Noises during Pregnancy.
Sound insulation of bedrooms is expensive and typically only granted to residents living close to the airport. We plan to investigate the effects of various aviation noises on sleep under controlled laboratory conditions and to investigate whether some of the sleep disturbing effects can be mitigated by introducing broadband noise into the bedroom or by wearing earplugs.
Patients admitted to the intensive care unit (ICU) undergo complex critical care treatment and are consequently surrounded by equipment and monitors contributing to high sound pressure levels. In addition, many medical and nursing ICU staff members work together with numerous visiting consultants resulting in an additional sound burden. As is already known, in the ICU environment, many activities carried out by healthcare professionals, require a high level of concentration. So, the noisy ICU environment causes interruptions in activities that require concentration and induce in this way, a higher potential for errors. The World Health Organization (WHO) and the Environmental Protection Agency (EPA) set standards for sound levels in hospitals with a recommendation for patient treatment areas. There is a clear trend for increasing hospital noise since the sixties. According to healthcare professionals, one of the strongest contributing factors of noise in the ICU environment are monitoring alarms as they occur very frequently. Additionally, ICU nurses experience high levels of stress towards clinical alarms and are becoming alarm fatigue, which means that the staff becomes desensitized because of an excessive number of alarms and may disable or silence alarms without checking the patient . Consensus dictates the importance of reducing sound pressure levels and the numerous alarm signals from monitor alarms in the ICU. In the study, we focus on busy predetermined areas in the ICU. This study aims to determine the effect of an intervention bundle, aimed at the reduction of "noise" (decibels) and its effect on health care professionals.
This study has two stages. At the first stage,the investigators will try to use noise detectors to investigate the status of noise exposure in the pediatric intensive care unit(PICU) and to analyze the main noise sources in it. At the second stage,the investigators will try to evaluate the effect of noise management on noise exposure and health outcomes of the pediatric patients in PICU.The investigators hypothesize that noise exposure in PICU is higher than the standard.The investigators also hypothesize that the implementation of the noise management will improve the noise exposure and health outcomes of the pediatric patients in PICU.
Centralisation of neonatal intensive care has led to an increase in postnatal inter-hospital transfers within the first 72 hours of life. Studies have shown transported preterm infants have an increased risk of intraventricular haemorrhage compared to inborns. The cause is likely multi-factorial, however, during the transportation process infants are exposed to noxious stimuli (excessive noise, vibration and temperature fluctuations), which may result in microscopic brain injury. However, there is a paucity of evidence to evaluate the effect of noise and vibration exposure during transportation. In this study the investigators aim to quantify the level of vibration and noise as experienced by a preterm infant during inter-hospital transportation in ground ambulance in the United Kingdom Secondary aims of the study are to: i) measure the physiological and biochemical changes that occur as a result of ambulance transportation (ii) quantify microscopic brain injury through measurement of urinary S100B and other biomarkers (iii) evaluate the development of intraventricular haemorrhage on cranial ultrasound iv) monitor vibration and sound exposure, using a prototype measuring system, during neonatal transport using both a manikin and a small cohort of neonatal patients. v) evaluate vibration and sound exposure levels using an updated transportation system modified to reduce effects.
