Reference

This microphone is a prototype produced jointly by the Cotral company, the ISL (Institut franco-allemand de recherches de Saint-Louis) and the LMSSC (Laboratoire de Mécanique des Structures et des Systèmes Couplés). It consists of an Alvis mk5 earmold combined with a STMicroelectronics MP34DT01 microphone. Several measures were taken to ensure optimum acoustic sealing for the in-ear microphone, in order to select the most suitable earmold.
