A degree of seal of an ear about a speaker port may be estimated by detecting touch contact between the ear and at least one touch sensor in fixed relation to the speaker port. The degree of seal is estimated based on the detected touch contact. Based upon the estimated degree of seal, the acoustic output of the speaker may be adjusted. The adjustment may compensate for perceived changes to the quality of the acoustic output resulting from the degree of seal. The at least one touch sensor may be a plurality of touch sensors spaced around the speaker port. Each sensor may have a truncated wedge shape, with a narrow end closest to the speaker port.

Un degré de bouchon d'oreille d'un port de haut parleur peut être estimé en détectant le rapport tactile entre l'oreille et au moins un capteur tactile en relation fixe avec le port de haut parleur. Le degré de bouchon est estimé en fonction du rapport tactile détecté. En fonction du degré estimé de bouchon, il est possible de régler la sortie acoustique du haut-parleur. Le réglage peut compenser les changements perçus dans la qualité de la sortie acoustique résultant du degré du bouchon. Le capteur tactile minimal peut être constitué de multiples capteurs tactiles entourant le port de haut parleur. Chaque capteur peut avoir une forme de cheville tronquée, avec une extrémité étroite la plus proche du port de haut parleur.
