Effectiveness of hearing protectors for the prevention of hearing loss in workers exposed to noise
(Universidad Privada Norbert Wiener, 2019-04-07) Candiotti Guzman, Cynthia Fiorella; Tintaya Puma, Sandra; Glenni Garay, Zarely Zabeli
The academic work is a Systematic Review that synthesizes the results of multiple investigations. The search was restricted to articles with full text submitted to a critical reading, using the GRADE system to assign the strength of recommendation. In the final selection, 10 articles were chosen, finding that 20% (02) of the total articles correspond to Spain. , another 20% (02) corresponds to Chile, 20% (02) more to Brazil, while 10% (01) corresponds to Mexico, another 10% (01) to Colombia, 10% (1) to Paraguay and finally another 10% (01) corresponds to the United Kingdom. These are mostly descriptive (40%), followed by quasi-experimental studies (30%), systematic review (10%), pre-experimental studies (10%), cohorts (10%), where of the total articles analyzed 90% affirm that hearing protectors are effective in preventing hearing loss, while 10% affirm that there is no significant information that supports the idea of better attenuation with the use of hearing protectors. The conclusion of this review is that hearing protectors are effective in preventing hearing loss in workers exposed to noise; There are also factors that can alter its effectiveness, such as the correct use of hearing protectors by the worker and training.

Effectiveness of the use of earplugs to reduce exposure to noise pollution in workers
(Universidad Privada Norbert Wiener, 2021-01-24) Fernández Torres, Margareth Johana; Mayorga Susanibar, Yosselin Karen; Palomino Taquire, Rewards
The study is a systematic review. In this project, 10 published scientific articles were included, no older than ten years. In addition, a search was conducted in the electronic literature of Epistemonikos, PubMed, Scielo, Dialnet to identify studies that reported on the effectiveness of the use of earplugs to reduce exposure to noise pollution in workers. Of the 10 articles included, 100% agree that the insertion buffers are effective, however, the level of noise attenuation provided in the manufacturer's technical sheets differs from that found in the test carried out for each of the protectors, in the In the case of the cup type, its effectiveness is 37% less than expected and for the insertion type, it is 59%. It is concluded that plug-type hearing protectors are effective in reducing noise exposure at different levels adjusted to different factors that can alter their performance index.
