Summary[edit]
| Description |
Русский: Перевод исследования National Institute for Occupational Safety and Health средств индивидуальной защиты органа слуха от шума (СИЗОС). Одно из первых исследований, установивших, что ослабление шума у работников на рабочих местах очень непостоянно; может быть близко к нулю; и в среднем многократно ниже получаемого в лабораторных условиях при сертификации. Выводя авторов этого исследования точно совпадают с результатами аналогичных исследований, проводившихся в течение 40 с лишним лет после него, при использовании новых моделей СИЗОС, и нового измерительного оборудования. |
