A sound-generating device for a probe for measuring otoacoustic emissions or for a hearing aid is disclosed, comprising a sound-generating module (12) designed to be inserted into a human ear canal (14). The sound-generating module (12) has at least one first sound transmitter (20) that emits a first sound field (24) distally, which exhibits a first sound pressure that is location-dependent. When inserted into the ear canal (14), the sound-generating module (12) is not airtight with respect to the ear canal (14), so that a reflected portion (27) of the first sound field (24) can penetrate into a proximal far field (46) and generate a first far-field sound pressure there.The sound generation module (12) has at least one second sound transmitter (38) which emits a second sound field (40) which has a second sound pressure that is dependent on location and generates a second far-field sound pressure in the proximal far field (46), wherein the second sound field (40) is adjusted such that in the proximal far field (46) the second far-field sound pressure is essentially the same as the first far-field sound pressure, but out of phase with it, so that in the proximal far field (46) the reflected part (27) of the first sound field (24) generated by the first sound transmitter (20) and the second sound field (40) largely cancel each other out.

This utility model discloses a dual-feed over-ear noise-canceling headphone, relating to the field of over-ear noise-canceling headphone technology. It includes an earphone shell, with a speaker mounting shell internally connected to it. A speaker is mounted on the right side of the speaker mounting shell, and a silicone pad is attached to the outer side of the speaker mounting shell. A bracket is rotatably connected to the outside of the earphone shell, and an extension bracket is slidably connected to the inner side of the bracket. A noise-canceling component is mounted on the other side of the speaker mounting shell. This dual-feed over-ear noise-canceling headphone uses a feedforward microphone and a feedback microphone to collect external ambient noise and residual noise within the earcups, respectively. The earphone shell also houses a speaker for playing audio signals and processed noise-canceling signals. The headphone includes a noise-canceling control circuit, including a feedforward filter and a feedback filter, which process the noise signals collected by the feedforward and feedback microphones, respectively.
