Résumé

A Radio Acoustical Virtual Environment (RAVE) is being developed to address issues occurring when communicating in noise while wearing Hearing Protection Devices (HPD). RAVE mimics a natural acoustical environment by transmitting the speaker’s voice signal only to receivers within a given radius, the distance of which is calculated by considering the speaker’s vocal effort and the level of background noise. To create a genuine RAVE, it is necessary to understand and model the speech production process in noise while wearing HPDs. Qualitative open-ear and occluded-ear models of the vocal effort as function of background noise level, exist. However, few take into account the effect of communication distance on the speech production process and none do so for the occluded-ear. To complement these models, quantitative data is used to generate quantitative open-ear and occludedear models, representing the relationship between vocal effort, communication distance, background noise level and type of HPD. These models can later be implemented within radio-communication headsets used in the proposed RAVE. Speech production models for occluded-ear accounting for the intended communication distance are presented in qualitative terms.
