An electroacoustical apparatus and method is described that alters the output properties of an audio device to improve the sound properties for both hearing impaired and normal hearing listeners. The device includes a coil element of specific design and may incorporate digital signal processing techniques to modify audio signal output. The electrical device and method of processing provides for the beneficial alteration of sound waves to an audio signal, and further modification of the audio signal to provide for improved loudness and clarity characteristics. The improved characteristics provide for greater intelligibility of the audio signal to persons with hearing impairments and to persons with normal hearing.

L'invention concerne un appareil et un procédé électroacoustiques qui modifient les propriétés de sortie d'un dispositif audio afin d'améliorer les propriétés acoustiques à la fois pour des auditeurs malentendants et normo-entendants. Le dispositif est constitué d'un élément de bobine de conception spécifique et peut inclure des techniques de traitement de signal numérique pour modifier une sortie de signal audio. Le dispositif électrique et le procédé de traitement fournissent une altération bénéfique des ondes sonores à un signal audio et une modification supplémentaire du signal audio pour des caractéristiques de force sonore et de clarté améliorées. Les caractéristiques améliorées fournissent une meilleure netteté phonique du signal audio aux personnes qui souffrent de troubles de l'audition et aux personnes ayant une audition normale.
