Surface stickiness and waviness of two-layer silicone structures for synthetic vocal folds

Body-cover models of vocal folds made of silicone rubber are increasingly used in voice research. The very soft cover layer often shows a residual stickiness. This study explored potential methods to avoid the stickiness while maintaining the softness and a flat surface structure. Therefore, 60 silicone samples werefabricated from different silicones and with different manufacturing procedures tosimulate the compound of cover layer and...
