摘要： A method for manufacturing a hearing device (100, 200) is disclosed. The hearing device (100, 200) comprises a speaker (2), a first chamber (4), and a sound channel (6) arranged between the first chamber (4) and the surroundings of the hearing device (100, 200) or a second chamber (8). An element (10) of a thermoplastic material being in a solid state is arranged in the sound channel (6). A laser light (12) is applied to the element (10) to thereby activate the element (10) to change from the solid state to a liquid state. The element (10) then changes from the solid state to the liquid state filling out a cross-section of the sound channel (6) and thereby sealing the sound channel (6). Finally, cooling of the element (10) is allowed leading to a change of the element (10) from the liquid state to solid state while filling out the cross-section of the sound channel (6).

摘要： The present invention relates to an earphone with active noise cancellation and to a headset with such an earphone.
The earphone (1) is adapted to be arranged in an operating position at a first ear (5) of a user (4) and, in the operating position, provide a first acoustic output signal (So) to the first ear (5). The earphone comprises: a first input unit (31) adapted to receive a first audio input signal (S I ); a first noise cancellation signal path (37) with a first microphone (26) and a first noise cancellation filter (32), wherein the first microphone (26) is arranged to receive ambient sound (S A ) from ambient space (7) with the earphone in the operating position and is adapted to provide a corresponding first reference signal (S R ), and wherein the first noise cancellation filter (32) is adapted to apply a first transfer function (H) to the first reference signal (S R ) to provide a first noise cancellation signal (S C ); a first output unit (33) adapted to provide a first audio output signal (S D ) by combining the first audio input signal (S I ) and the first noise cancellation signal (Sc); a first electroacoustic transducer (23) adapted to provide the first acoustic output signal (So) in dependence on the first audio output signal (S D ); and a first noise cancellation controller (34) adapted to adaptively control the first transfer function (H) of the first noise cancellation filter (32) to cause the first acoustic output signal (S O ) to counteract ambient sound (S A ), such that, with the earphone in the operating position, the level of ambient sound (S A ) arriving at the first ear (5) is reduced, while still allowing desired sound from the first audio input signal (S I ), to pass through.
The earphone (1) is characterized in that it further comprises a level analyzer (35) adapted to provide, based on an analysis of the first audio input signal (S I ) and/or the first reference signal (S R ), a sound level estimate (L S ) indicating a total sound level at the first ear (5) and to compare the sound level estimate (L S ) with a predetermined threshold (L T ) indicating a noise floor level; and in that the first noise cancellation controller (34) further is adapted to, in dependence on the comparison, control the wide-band gain (G) of the first noise cancellation signal path (37) to cause a decrease (ΔG) of the wide-band gain (G) in time periods wherein the total sound level at the first ear (5) is below the noise floor level compared to time periods wherein the total sound level at the first ear (5) is above the noise floor level.
The invention may e.g. be used to reduce noise perceived by a user while listening to speech or music through an active noise cancellation earphone and/or to improve the comfort perceived by the user when using an active noise cancellation headset in low-noise environments.

摘要： Disclosed is a method and a headset for reducing pop-noise in voice communication between a user and a far-end device. The headset is configured to be worn by the user. The headset comprises a microphone boom having a first end and a second end. The first end is configured to point towards the mouth of the user, when the user is wearing the headset. The headset comprises a first, a second and a third electro-acoustic input transducer for reception of audio input signals. The first, second and third electro-acoustic input transducer are provided in the microphone boom. The headset comprises a first beamformer configured for providing a voice signal. The voice signal is based on a first input signal from the first input transducer. The first beamformer is configured to optimize the voice-to-background noise ratio. The headset comprises a second beamformer configured for providing a pop-noise signal. The pop-noise signal is based on the first input signal from the first input transducer, the second input signal from the second input transducer, and a third input signal from the third input transducer. The second beamformer is adaptively configured to cancel voice and background noise while not cancelling pop-noise. The headset comprises a comparator configured to repeatedly compare the pop-noise signal to the voice signal within each of multiple frequency bands to determine time periods and frequency bands having pop-noise. In the determined time periods and frequency bands having pop-noise, the pop-noise, in an output signal configured to be transmitted to the far-end device, is reduced.
