Ukuze unciphise ingozi yokungezwa, isivikeli sezindlebe singasiza ekunciphiseni izinga lomsindo. Abantu kufanele bagqoke isivikelo sokuzwa uma umsindo noma izinga lomsindo lidlula ama-decibel angu-85 (A-weighted) noma i-dBA. Izindlebe ze-YUNBOSHI zinikeza ulwazi olunethezekile noluhlala isikhathi eside kubantu baseshabhu yokusebenzela enomsindo noma ezindaweni zomphakathi. Njengoba iwuchwepheshe bezixazululo zokulawula izinga lokushisa nomswakama, i-YUNBOSHI TECHNOLOGY inikeza amakhabethe okomisa, kanye nemikhiqizo yokuphepha, njengama-muffs ezindlebeni, amakhabethe amakhemikhali kumakhasimende emhlabeni wonke. I-YUNBOSHI TECHNOLOGY igxile ocwaningweni nasekuthuthukisweni kobuchwepheshe bayo bokulawula ukuswakama ezimakethe eziningi kwezemithi, i-elekthronikhi, i-semiconductor kanye nokupakishwa. Besilokhu sisebenzela amakhasimende avela emazweni angama-64 njengeRochester--USA kanye ne-INDE-India phakathi neminyaka.
