Noise measurements at the workplace
Possible noise sources per sector:
- industrial sector
- mining sector
- construction sector
- agricultural sector
- fisheries sector
- transport sector
- services sector
Noise sources exist virtually everywhere where there are workplaces, and they can be found wherever a human being works.
Noise can be a severe problem in numerous workplaces, not only in construction worksites and industrial companies but also in other work environments, such as farms or bars, schools, or concert halls. Regardless of the type of workplace, three basic steps are aiming to protect workers from the harmful effects of noise:
- noise risk assessment
- anticipating measures to reduce or avoid the risk based on the results of the noise risk assessment
- continuous monitoring and reviewing of the effectiveness of noise reduction measures on-site
There is an appropriate hierarchy of noise reduction measures, which must be followed to ensure the health and safety of workers:
- elimination of noise sources
- noise reduction at its source
- collective regulatory measures
- improving work organization and workplace configuration
According to LST EN ISO 9612: 2009 and LST EN ISO/IEC 17025 we:
- prepare an analysis of activity (work, task, operation)
- choose the measurement s strategy
- make the measurements
- evaluate the measurement errors (uncertainty)
- calculate and present the measurement results and errors (uncertainty)
- provide the statements of compliance
- provide the interpretations and opinions
We measure:
- equivalent constant sound pressure level Lp, A, eqT
- maximum instantaneous sound pressure level Lp, Cpeak
