Noise, working environment control

The mine idler s failure work presents by inflexibility or stuck. The practical experience requires a good performance of idler s life, reliability, rotational resistance, sealing performance, as well as noise and vibration. To address these requirements, one must control strictly various aspects as the design, material selection, manufacturing, assembly, testing and working environment. However,... 

These information sources can be used independently or in combination. Direct observation includes inspection activities and the monitoring of the work environment (e.g. temperature, dust levels, solvent levels, noise levels) and people s behaviour. Each risk control system should have a built-in monitoring element that will define the frequency of monitoring these can be combined to form a common inspection system. 

Noise is controlled inside plants to provide a safe, healthful, and comfortable work environment. Noise is controlled outside plants to avoid degrading the neighborhood environment. Noise can be controlled directly at the source, such as a fan or transformer, where it is produced. Noise can also be controlled along the paths that it travels from the source to the receiver, for example, by the use of a barrier or a muffler. Noise can also be controlled at the receiver, for example, by earmuffs or earplugs, both of which were discussed earlier. This section addresses control of plant noise at the source and along propagation paths. 

We believe that this study might contribute to physical educators regarding the prevention and control of Noise-Induced Hearing Loss (NIHL), as well as vocal problems within the scope of employment. More than promoting preventive campaigns together with teachers, there is a need to invest in measures that will promote a healthy working environment to its employees. 

Common controls. Noise can be controlled in the work environment by isolation or enclosure of the source of the noise. Control rooms can be constructed in treatment plants to provide a low-noise environment for operators. If operators must enter high-noise areas they can be required to use personal hearing protection to protect against high noise levels. 

Noise can constitute a danger to health, and therefore adequate precautions must be taken to protect personnel who are required to be in such an environment. The Health and Safety at Work, etc. Act 1974 has the power to control noise emissions, but the subject is complex. If it is anticipated that noise will exceed acceptable levels then... 

Though the images were taken in controlled environment under fixed illumination of light of 120 lux with the help of tungsten filament lamp, but there were some noises in the picture. To remove these noises a simple median filter found to provide reasonable good performance but it is computationally intensive. For that pseudo-median filter [19] was used in the work, as it is computationally simpler and possesses many of the properties of the median filter. This filtering process often helped to obtain smooth continuous boundary of the mango. 

The broad intent of environmental ergonomics is to create prevailing ambient conditions that are comfortable, acceptable and do not compromise work performance or worker health (Hedge, 2005a). The relevant standard, BS/EN/ISO 11064-6 2005 (Ergonomic Design of Control Centers. Part 6. Environmental Requirements for Control Centers), states that factors such as lighting, humidity, temperature, vibration, noise, and aesthetics must be addressed, because poor environments can seriously affect operator performance.
