Background: There is a great concern for the possible adverse effects of cell phones and noise waves and it looks these wave effects on the individuals’ health. Thus, the present study was conducted to examine the effect of cell phone waves, severity noise, and simultaneous effect of cell phone waves and severity noise on sperm motility and sexual hormones in adult male rats. Materials and Meth...
cardiovascular adverse effects are interesting aspects of occupational noise exposure. one possible mechanism of these effects is an alternation in hypothalamic-pituitary-adrenal axis. our aim was to measure salivary cortisol response to relatively high-intensity noise exposure in a controlled randomized trial study. we exposed 50 male volunteers to 90 dba noise for 20 minutes and compared thei...
Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...
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...
noise is considered as one of the harmful factors at industrial environments. it affects human health in different aspects including harmful influences on auditory, vision, neurological and psychiatric systems, hormones, physiological and mental systems. paying attention to the importance of hormonal effects on human body seems to possess crucial importance. the aim of the present study is to i...
abstract background: previous studies have indicated an unspecific correlation between noise exposure and blood pressure disturbances. blood pressure disturbances could be caused by the environmental hazards such as noise exposure. the aim of this study is to analyze whether there is a relationship between noise exposure and hypertension. methods: atotal sample of 218 workers working in a small...
Background and purpose: Irreversible damage to the inner ear is known as noise-induced hearing loss (NIHL). Exposure to excessive noise can affect the expression of genes in molecules involved in development of NIHL. SLC26A4 gene or PDS is responsible for causing both syndromic and non-syndromic deafness and is located at DFNB site. The aim of this study was to investigate the expression level ...
original article introduction: a practical solution which is sometimes efficient for noise control in the receiver locations is to enclose workers in an acoustic cabin. accordingly, prediction of the noise insulation performance is regarded as an important aspect of the design a personnel cabin. this study empirically aims to design an acoustic cabin using sandwich panels in a typical metal i...
noise-induced hearing loss (nihl) is the most common complication of long-term noise exposure, though there are some other complications due to exposure to noise. metabolic complications of the noise exposure are being evaluated in recent studies. we aimed to assess the relationship between nihl and lipid profile, and fasting blood sugar (fbs). in this cross-sectional study, 462 ...
A four year long research programme divided into four phases has been designed for the first time to assess the combined Noise-Air quality and combined exposure to Noise-Air pollution at the curbside open-air microenvironment of Kolkata city, India. The results and the findings of the different phases of study had already been published. The objective of the review work is to fuse the findings ...
