“…Regarding the attenuation provided by the 3M 1100 earplugs, other than the data provided by the manufacturer, differences in terms of workers' protection in both the cases in which they are correctly inserted or not, were also estimated. In this case we used the results obtained in another our previous laboratory test [15], in which 100 subjects were asked to wear earplugs before and after the training on their correct use. For these laboratory tests, modified earplugs were used, in which a little plastic tube was inserted in the plugs in order to capture the noise inside the ears by the use of a micro-microphone connected to it.…”

In this study, an estimation of the behavior of three different passive and active personal ear protection equipment was done in order to evaluate their performances when used in a limestone quarry plant. Twenty measure points were chosen for the characterization of the noise emitted in the plant and for the calculation of the workers' noise exposition. Starting from the data we previously measured in laboratory tests, the noise reduction curves, characteristics of each protective equipment, were calculated for different configurations or ways of using. Results show that all the protection equipment are potentially able to reduce the noise level under the lower exposure limit in all the measured positions, but in most of the cases they produce hyper-protection. Differences were found for different ways of using or settings. When earplugs are not properly inserted, the noise could overcome 80 dB(A) in some of the points of our case study. When active earplugs are set to the maximum volume, the provided protection wasn't found to be sufficient in all of the noisier points of the plant. In some cases, depending on the spectra and amplitude of the external noise, the sound produced by active earplugs can also be higher than that measured in the external environment. On the contrary, when the earplugs are set on the middle volume, the protection was found to be always optimal. Since noise passing through active earplugs can be attenuated or amplified according to the amplitude of the external noise, the perceived sound is much more homogeneous, especially when passing across points at different noise levels, compared to that provided using passive earplugs. In conclusion, active earplugs, when properly set, could be the better choice, especially in those cases in which workers need to move across points at different noise levels. However, important is to correctly estimate the external noise and the properties of the active earplugs in order to give instruction to workers for their correct settings, so as to avoid both the hyper-than the under-protection.

“…If that estimated behavior should be confirmed in real field measures, the use of this kind of earplugs at volume 3, other than resulting to be not efficient in reducing the noise under the lower exposure limits, could also be detrimental in some of the quarry points (points: 6,15,16).…”

“…In addition, human senses react differently in relation to the experience of noise exposure [15]. The negative effects of exposure to this physical agent are also studied for workers in the context of the workplace; many studies confirm that prolonged exposure to high and continuous noise levels generates annoyance and risks to human health [16][17]. In addition, the higher rates of travel in urban settings can lead to higher noise levels than in flat agricultural areas.…”

Noise can be generated by different causes, and the great variation in noise levels is determined by the cumulative effect of 9 have reported associations between exposure to noise, vibration, and annoyance and show that the greatest effects in terms of population prevalence are due to sleep loss and severe annoyances. Moderate speed vehicles, quiet engines, special road surfaces, smooth flow, etc. may be important to achieve comfort improvement. These results motivate the need for noise assessments. The primary objective of this work was to study the effects of noise generated by vehicular traffic in the urban context of Rome and to identify a relationship with level vibrations generated by the same traffic. The data illustrate the measurement campaign carried out in different sites for the purpose of detecting noise levels within the structures. Subsequently, the data obtained compared with vibration levels, and the results confirm a strong relationship between the two physical agents.
