Background & Aims: Noise pollution is becoming a severe issue for the patients admitted in intensive care units (ICUs). For the reduction of noise pollution in hospitals, researchers recommend proper training and adherence to protocols. The present study aimed to assess the effect of the training of nurses on the reduction of noise pollution in ICUs. Materials & Methods: This clinical trial wa...
Comparing Intensity Elicited Maximum Reflex Amplitude Between Noise Induced Hearing Loss & Acoustic Trauma at 1kHZ, Contralaterally, and Investigate Relationship Between Amplitude and Hearing Impairment
noise level intensity in cities, due to the daily increasing sources of noise producing agents in one respect, and the lack of noise absorbants in the other respect, is rising. the high influence of intense noises on the human body and mind are found to have detrimental effects. the ideal is to have an optimal condition of noise. in this paper the living and relaxing areas, in view of main acou...
a bstra ct background: continuous high - intensity noise in the neonatal intensive care unit (nicu) is stressful for premature infants and its reduction is considered as a nursing care. this study aimed to evaluate the effects of earmuffs’ use on the physiologic and motor responses of premature infants. materials and methods: this is a clinical trial conducted on 64 premature infants admitt...
In this paper, a stochastic term is added to the classical generalized nonlinear Schrödinger Equation to describe the noise generated when light pulses propagate in a fiber. It has been shown that the generated supercontinuum light source fluctuates up to 50% of its output temporal intensity profile due to noises of different sources. The simulation method devised has been applied to the propag...
noise is defined as unwanted or objectionable sound. human susceptibility to noise varies in terms of intensity, altitude, timbre of sound, personal sensibility, age, and history of ear disorder. noise pollution which is the result of heterogeneous and uncontrolled developments of cities is one the serious problems in large cities of iran. although noise pollution in kerman (located in southeas...
