耳罩防音性能的客觀法測試標準

Objective Testing Standard for Measurement of Acoustic Performance of Ear Muff

本研究探討聽力防護具防音性能的測試方法，建立了耳罩的插入損失與耳罩夾緊力的測試標準，與設計了相關的假人（ATF）夾具與測試夾具。同時根據本研究建立的測試標準、測試程序與夾具，進行了可行性檢測與耳罩插入損失實測。在本研究中，同時也提出了測試時應特別注意的事項。這些測試標準、八種詳細測試程序與夾具，將有助於建立耳罩插入損失國家測試標準與協助相關單位建立測試的技術。

In this work, the testing method of the acoustic performance of the hearing protectors has been studied. The draft testing standard for the measurement of the insertion loss and application force of ear muff has been established. The acoustic test fixture and application force test stand have been designed and the validity of these test fixtures has been verified. These draft testing standard, eight detailed measurement procedures and test fixtures may help establish the CNS of insertion loss of ear muff. A few notes have been given when testing the acoustic performance of ear muffs.
