Résumé
Inserting an earplug in the earcanal’s entrance can lead to various discomforts, one being the occlusion effect (OE),typically described as a distorted perception of one’s own voice. This discomfort can lead to users misusing orremoving their earplugs, significantly lowering their efficiency. Therefore, it is critical to reduce the OE generatedby earplugs to enhance user comfort. However, the influence of factors such as earplug type, insertion depth andbackground noise level on the OE remains poorly understood. Consequently, this ongoing research aims to identifythe underlying factors contributing to the discomfort generated by the OE during speech. To achieve this, tests areconducted in laboratory conditions with 33 normal hearing participants with varying levels of experience in dailyearplug use for work or personal activities. The OE is assessed subjectively using a user comfort questionnairefocused on the perceived and experienced OE, and objectively using surrogate earplugs for in-ear microphonicmeasurements. Multiple combinations of earplugs, insertion depths and background noise levels are tested toobtain a ranking of the conditions generating more or less OE, and to identify the factors contributing to thediscomfort. The improved understanding of the OE resulting from this study will allow manufacturers to developmore comfortable and, as a result, more efficient earplugs.
