Applied Standards
The ISO 11202 standard provides a comprehensive set of guidelines for conducting sound pressure level measurements in various types of workplaces, including industrial facilities like factories. It specifies the necessary equipment, measurement techniques, and procedures required to ensure accurate results.
One key aspect addressed by this standard is selecting suitable instruments for measuring SPLs. According to ISO 11202, it is recommended that only Class 1 or higher sound level meters be used due to their precision and stability over time. Additionally, these devices must comply with IEC 61672-1:2013, which sets stringent performance criteria for sound level meters.
Another important factor mentioned in ISO 11202 is proper placement of the measurement points within the workspace. The standard recommends placing SLMs at least one meter away from any reflective surfaces such as walls or ceilings to minimize reflections that could distort measurements. Furthermore, it suggests positioning sensors near workers' ears since they are most likely to experience high noise levels during their shifts.
Regarding data collection methods prescribed by ISO 11202, the standard emphasizes taking multiple readings over extended periods rather than relying on single-point measurements taken at isolated moments. This approach allows for more representative samples of actual SPLs experienced throughout an entire workday. Additionally, ISO 11202 recommends recording not only A-weighted sound pressure levels but also C-weighted values as well since they reflect different frequency ranges and thus offer a broader perspective on overall noise exposure.
The analysis process outlined in ISO 11202 involves several steps aimed at deriving meaningful insights from the collected data. First, raw measurements need to be corrected for environmental factors such as temperature, humidity, altitude, and barometric pressure according to established correction equations provided by the standard. Next, average sound levels over specific intervals should be calculated using appropriate averaging methods like time-weighted averages or energy-weighted averages.
Finally, ISO 11202 recommends comparing these calculated values against permissible exposure limits specified in relevant national and international standards such as OSHA PELs (Permissible Exposure Limits) or EU Noise Directive limits. If any measured levels exceed these thresholds, further investigation into the sources of excessive noise is warranted to implement corrective measures.
By adhering strictly to ISO 11202 guidelines during all stages of sound pressure level testing, organizations can ensure they obtain reliable and valid data that accurately reflects true SPL conditions in their workplaces. This compliance not only helps maintain regulatory adherence but also enhances overall occupational health & safety practices.
