Methods: The present study was single-blind,quasi-experimental study. A total of 60 patients were selected using the purposivesampling method. Quality of sleep was measured with PSQI on the first day in admission,then after three nights of admission without any intervention for control group and forthe experimental group quality of sleep measured by white noise with intensity of 50-60 dBthen Quality of sleep was measured with PSQI. Data were analyzed by SPSS 13 software.
Moreover, unfavorable quality of sleep as a stressful condition may aggravate ischemia andmyocardial infarction.8 The reason ofinterrupted sleep in the coronary care unit is multi factorial of which noise is oneimportant factor.3 Noise is defined asunwanted sounds that could have negative psychological and physiological effects.9 Noises are an unavoidable part of our life,Noises may be made following environmental factors or human activities. The World HealthOrganization (WHO) and Environmental Protection Agency (EPA) suggest that the level of noiseat night in hospitals will not be higher than 35-40 dB.6,10 However, a study showed thatthe level of noise in CCU at night became higher than 80 dB.11 A study performed by Xie et al., showed that noises comprised17-57.6% of patients' awakening triggers in CCU, and among the noise sources were sounds ofmonitors, staff conversations, phone ringing, ventilation and heating systems, and othermedical devices. The patients are most disturbed by staff conversations andalarms.6
Furthermore, Zakeri Moghaddam's et al.,12 study performed in Iran showed that most of the patients admitted to thecoronary care unit reported the staff conversations, patient conversations, telephoneringing, and alarms of monitors and devices as the environmental factors of sleep disorder.The noise intensity of staff conversations, monitors, and infusion pumps are 59-90 dB, 72-77dB, and 73-78 dB, respectively.13 Anotherstudy revealed that most of care delivery is performed at 8:00 pm, midnight, and 6:00 am,which showed noisy times in coronary care units.14 It is necessary for nurses take measures in order to play a crucialrole in diagnosing and eliminating factors contributing to sleep disorders and treatit.15
The study population included the patients admitted to the coronary care unit of ShariatiHospital, Tehran, Iran in 2013. The sample size was estimated 62 patients (31 subjects ineach of the control and experimental groups) with respect to the values reported in previousstudies with a standard deviation of 3, accuracy level of 3, confidence level of 95%, testpower of 0.8 and accounting for the possibility of attrition rate. The patients wereincluded in the study using the purposive sampling method with the inclusion criteria asfollows: minimum age of 30 years old; CCU stays, at least for three nights; awareness oftime, place and people; having hemodynamic stability; capable of hearing; non- receiving ofanesthetic medications, drugs and diuretic drugs during three- night stay in CCU.20-22 Tominimize the sleep disrupting factors, the study was conducted in the same CCU for bothgroups. At the beginning of the study, the objectives of the study were explained to allcandidate patients. The confidentiality of information obtained from them was also mentionedto them, and they were assured that they could opt out of the study at any stage of itwithout there being any impairment in their treatment, then, the amount of noise wasmeasured for three nights in the coronary care unit from the change time of night shift inthe morning (from 7 PM to 7 AM of the next day).
The quality and mean hours of precious sleep of the control group samples on the first dayof hospitalization were measured and assessed by using the Pittsburgh Sleep Quality Index(PSQI) and the sleep log to evaluate the average sleep time. In the following, with theinterval of three nights stay in the CCU without any action, the quality of sleep for threenights was measured again with the same instrument. After completing the control groupsampling, the sampling of the experimental group was started, and similar to the controlgroup, the quality and average time of the patients' previous sleep were initially measuredon the first day. Then, the white noise was broadcasted for the patients with the intensityof 40-50 dB for one hour during three nights in the noisy hours of the ward, which werepreviously determined through measuring the sound intensity over the night (8 PM to 9 PM atnight and 11 to 12 PM at night). After this period, the quality of sleep in patients wasagain measured with the same tool for three nights.
According to the previous studies, the environmental noise is an important sleepdisturbing factor,23especially inCCU.9,24In spite of many claims aboutthe effectiveness of reducing noise in the critical care environment on improved sleepquality of patients; few studies have assessed the effect of such interventions.10 The score of sleep quality of the controlgroup after the study was increased significantly as compared with before the study(P

You may have heard of white noise. The steady, static-like sounds from it can drown out disturbing noises and help you sleep better. But have you heard of pink noise and brown noise? Growing research shows that these lesser-known color noises can also help calm you or improve your sleep quality.
Pink noise uses a consistent frequency, or pitch, to create a more even, flat sound, like a steady rain, wind rustling through trees, or waves on a beach. Its added depth and lower waves filter out higher sounds. As a result, you hear more relaxing, lower-frequency sounds.
Blue noise. Its power increases as the frequency goes up. Blue noise sounds slightly shriller than pink and white noise. Imagine the hissing noise you hear when a water spray is turned on.
For some people, the grainy static sound you hear in white noise can improve sleep. It helps by masking the background noise and tuning it out. One recent study found that 38% of people fell asleep faster listening to white noise.
Pink noise reduces the difference between the background hum and loud, jarring noises that jolt you out of sleep, like a door slamming, a car horn honking, or someone snoring. So it may help you fall asleep faster and keep you in a deep sleep longer. You may also feel more rested when you wake up.
In 2016, I captured footage of Donald Trump supporters throwing Nazi salutes in celebration of his presidential victory. Ever since, I have been embedded in the alt-right as a journalist and documentarian. I saw far-right rhetoric surging on college campuses and in mainstream American politics, and white supremacists reaching millions online. What made white-power ideology so intoxicating?
Introduction: Undisturbed sleep has been shown to be important for both health and quality of life (Medic et al. [7]). The World Health Organization estimates that nearly 25% of the population suffers from disturbed sleep due to environmental noise (Health TWECfEa, [2]). Sleep disturbance associated with elevated noise levels is particularly prevalent in metropolitan areas. Our study tested the hypothesis that white noise would improve sleep in New Yorkers complaining of sleep difficulty due to elevated sound levels.
Methods: Ten adult participants were included in this study. All participants were recruited from a New York City based sleep clinic. Inclusion criteria was based on the presence of sleep disturbance and the reporting of high levels of environmental noise in participants' sleep location. The study was conducted using a within-subject, ABA design, with baseline, treatment phase, followed by another baseline (washout) period. Each phase lasted one-week, during which noise level and sleep were assessed. The treatment consisted of the application of a white noise device (Dohm Classic by Marpac, LLC) in the participants' bedroom. Sleep parameters were measured subjectively using the Consensus Sleep Diary (Carney et al. [15]), and objectively using a Motionlogger Actigraph.
Results: Paired sample t-tests were conducted to evaluate the hypothesis that white noise improves sleep in a high noise environment. Significance was found on the variables WASO, as measured by actigraphy, t(9) = 3.438, p = 0.007 and sleep latency as measured by sleep diary, t(9) = 2.947, p = 0.016. There was a trend toward significance on the number of awakenings during the night, as measured by sleep diary, t(9) = 2.622, p = 0.028 (Holm's sequential correction of p-value required a value of
Conclusion: Our data show that white noise significantly improved sleep based on subjective and objective measurements in subjects complaining of difficulty sleeping due to high levels of environmental noise. This suggests that the application of white noise may be an effective tool in helping to improve sleep in those settings.
Ambient noise refers to the all background noise that reaches the human ear. It's like the natural soundtrack of the world we live in, consisting of a mix of various sounds, such as the hum of traffic, chirping birds, rustling leaves, distant conversations or the gentle patter of steady rain.
Imagine yourself in a bustling city park or near a flowing river; the collective blend of these sounds creates the environmental noises unique to that setting. Ambient noise is diverse and dynamic, reflecting the character of a specific location. It sets the tone of our surroundings and can have both calming and invigorating effects on our senses, enriching our experiences as we go about our daily lives.
White noise refers to noise that is produced by combining of all audible sound frequencies. If you took all of the imaginable tones that a human can hear and mashed them together, you would have white noise.
