A study of the occlusion effect mechanism and the influence of the earmould properties
The present report studies the mechanism of the occlusion effect by means of literature studies, experiments and model estimates. A mathematical model of the occlusion effect is developed. The model includes the mechanical properties of the earmould and the airborne sound as well as the body conducted sound from own voice. These aspects are new in the sense that previous studies disregard the earmould mechanics and includes only one sound source placed in the ear canal.
