How Sound Measurement Helps Us Meet Safety Standards

At TMI, we are committed to excellence in manufacturing our machines, ensuring they not only operate optimally but also meet the highest safety standards. A crucial aspect related to operator safety is the level of noise and the exposure time they may experience during normal operation.

Directive 2006/42/EC requires indicating the emitted noise level, while RD 286/2006 on the protection of health and safety of workers sets a limit of 85 dB(A) as the maximum allowed, beyond which hearing protection is required for workers. Although our machines are highly automated and operator presence is not continuous, we strive to minimize noise emission levels, aiming to keep them below the 80 dB(A) threshold. These values ensure that operators can work in a comfortable and safe environment.

We collaborate with reputable entities in inspection, testing, and certification to carry out necessary tests, following the guidelines established in standard EN-415-9, specific to our range of machinery. Multiple acoustic measurements are taken at corresponding perimeter points, considering variables such as sacks produced per hour, dimensions, and weight of the produced sacks.

It's important to consider the environment where measurements are taken, as factors like room dimensions and materials can influence sound propagation. To correct for this effect, we emit a known sound and then analyze the measured result at the test site. Thanks to these corrective measures, we obtain more precise and reliable results.

The final result is a "weighted A-weighted sound pressure level" as accurate as possible, which meets our goal of staying below 80 dB(A). This exempts us from calculating the "weighted A-weighted sound power level," as stipulated in the Machinery Directive. At TMI, we strive to ensure a safe and comfortable working environment for all our operators, meeting the highest standards of quality and safety.
