background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

INTRODUCTION Noise is one of the harmful agents to health that is present in the various branches of economic activity. Hearing loss and tinnitus are among the most frequently reported complaints by workers exposed to occupational noise. OBJECTIVE To analyze the hearing and tinnitus in normal-hearing workers exposed to occupational noise. METHODS This is a cross-sectional analytical trial i...

background: in dental practical classes, the acoustic environment is characterized by high noise levels in relation to other teaching areas. the aims of this study were to measure noise levels produced during the different dental learning clinics, by equipments used in dental learning areas under different working conditions and by used and brand new handpieces under different working condition...

Longitudinal studies of hearing in workers in selected industries in Canada have shown that the effect of continuous high-level noise exposure is an increase in detection threshold of about 1 1/2 decibels per year. This is in contrast to 1/2 dB per year for non noise-exposed office workers in the same plants. Personal hearing protectors, in the form of ear plugs and muffs, have been chosen as a...

this paper tries to determine efficiency of noise control method using fuzzy logic and based on collected data. from among various methods of noise control in workplace, sex methods (enclosure, installing noise absorber, enclosure and absorber, active, and administrative control, and personal protective equipment) were typically selected based on experts' judgment. for each of selected control ...

Simultaneous exposure to carbon disulfide and noise may have a combined effect on hearing impairment. In this study we investigated hearing loss in 131 men with exposure to noise [80-91 A-weighted decibels; dB(A)] and CS(2) (1.6-20.1 ppm) in a viscose rayon plant. These men were compared with 105 men in the adhesive tape and electronic industries who were exposed to noise only and with 110 men ...

noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. a common problem in imaging systems by using cmos or ccd sensors is appearance of  the salt and pepper noise. this paper presents cellular automata (ca) framework for noise removal of distorted image by the salt an...
