Comparison of Mid Ear Canal (MIRE) and Tympanum (Ear Simulator) LocatedMeasurements on an Artificial Head for the Assessment of an Earmuff in Impulse Noise Exposure

摘要

Measurements of the response and the dynamics of a typical MIRE frame wereperformed using impulse noises in free field. The insertion loss (IL) of a Peltor H7A muff was determined using a MIRE device mounted on the ISL artificial head (AH) in high level impulse and low level steady state noise exposure (grazing incidence), and compared to the IL obtained simultaneously from the AH itself. Additionally, these results were likened to data obtained with the subjected method (REAT) and derived from the literature.
