Embodiment Construction

[0018] figure 1 The headset 10 in the headset includes a first earphone 1, a second earphone 2 and a headband 3 that mechanically connects the earphones 1 and 2. The headset 10 is shown arranged on the head of a user 4 of the headset 10 , wherein each of the earphones 1 , 2 is arranged in a respective operating position at a respective ear 5 , 6 of the user 4 . Ambient Sounds from User Environment 7 A , ie the ambient space, penetrates and / or surrounds the structure of the earphone 1 , 2 towards the user's ear 5 , 6 . The headset 10 receives an audio input signal S from an external device 8 such as a headset dock, computer, desk phone and / or mobile phone. I , and the earphones 1, 2 provide respective acoustic output signals S to the respective ears 5, 6 O . The external device 8 may comprise a user interface 9 for detecting manipulations by the user 4 and may thus provide a corresponding user input signal S to the headset 10 U . The headset 10 also includes structural an...

Abstract

The invention relates to an earphone with an active noise reduction function and a headset with an active noise reduction function. The earphone includes a level analyzer adapted to provide a sound level estimate indicative of a total sound level at the first ear based on an analysis of the first audio input signal and / or the first reference signal, and to compare the sound level estimate to a predetermined threshold indicative of a noise background level. The earphone also includes a first noise reduction controller further adapted to control a broadband gain of the first noise reduction signal path in accordance with the comparison such that the broadband gain is reduced in a time period in which a total sound level at the first ear is lower than a noise background level than in a time period in which the total sound level at the first ear is higher than the noise background level. The earphone disclosed in the present invention can be used, for example, to reduce noise felt by a user when listening to speech or music through an active noise reduction headset and / or to improve comfort felt by the user when using an active noise reduction headset in a low-noise environment.

Description

technical field [0001] The invention relates to an earphone with active noise reduction and a headset with such an earphone. For example, the present invention can be used to reduce the noise that the user feels when listening to speech or music through the active noise reduction headset and / or improve the user's comfort when using the active noise reduction headset in a low-noise environment. Background technique [0002] Headphones and headsets with active noise cancellation (ANC) (sometimes called active noise reduction (ANR)) are known in the prior art, which provide an acoustic output signal that cancels out ambient sounds , so that the level of ambient sound reaching the user's ears is reduced. [0003] International patent application WO 2014070836A2 discloses an ANR headset (headphone), which includes: an earcup configured to be coupled to a wearer's ear to define an acoustic space, the acoustic space includes the wearer's ear canal The air space and the space with...
