The random noise test of analog to digital converters recommended by the IEEE 1057 Standard for digitizing waveform recorders is studied. heuristically derived expression presented estimation standard deviation experimentally validated. suggests a triangular stimulus signal. Here we will show how use sinusoidal signal carry out test. influence offset and amplitude on error also analyzed an comp...

background noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. cortisol as a stress hormone is used in noise-induced stress assessments. objectives the aim of this study was to measure and compare saliva cortisol concentrations in the morning and evening in normal work day and rest day in both case and control groups and to assess the associ...

background and aim: auditory processing disorder and dyslexia have been reported by many studies as having high comorbidity. the purpose of the study was to investigate the effectiveness of central auditory processing rehabilitation program on speech reception in noise and dichotic listening in dyslexic students. the research was quasi-experimental, including a pretest, posttest and a control g...

environmental pollution plays a destructive role in the daily life of industrialized communities and due to their negative impact on the society they are always under close investigation.  besides well-known pollutants substantial, all major international health organizations consider noise pollution as an important health problem. in this study, we have used an animal model to study the effect...
