1. A method for enhancing audibility, localization and/or speech intelligibility of communication devices worn on the head or in the ear for a user with normal hearing or hearing loss, comprising:
- providing active control of sound and of unwanted acoustic noise,wherein the active control is achieved by a feature selected from the group consisting of;
active feedforward control of sound and of unwanted acoustic noise;
active feedback control of sound and of unwanted acoustic noise;
active control of the amplitude and/or frequency of a desired sound and/or unwanted acoustic noise, and any combinations thereof.

24. A communication device worn on the head or in the ear of a user for enhancing audibility, localization and/or speech intelligibility of sounds, comprising:
-
a first electro-acoustic device, wherein said first electro-acoustic device generates a first sound to said user; a second electro-acoustic device, wherein said second electro-acoustic device senses a second sound for said user, and wherein said first sound is different from said second sound; and a controller, wherein said controller is selected from the group consisting of an analog controller and a digital controller, wherein the controller provides active control of sound and of unwanted acoustic noise, and wherein the active control is achieved by a feature selected from the group consisting of;
active feedforward, active feedback, active control of the amplitude and/or frequency of a desired sound and/or acoustic noise, and any combinations thereof. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
