    Abstract: Headset for connection to a telephone apparatus, said headset comprising a capsule with a built-in receiver, and on which there is mounted a boom with a microphone. The headset is connected to a telephone apparatus by means of a wire with associated jack connection, and the headset has associated amplification and adjustment circuits for both the microphone and receiver, manual operating elements for the setting of said amplification and adjustment circuits, and switch elements for changeover depending partly on the type of microphone in the telephone apparatus and partly on the polarity of the telephone apparatus' microphone and receiver wires. The amplification and adjustment circuits are built into the headset capsule, so that the use of a separate connection box is avoided, and the manual operation elements are placed on the capsule. The switching elements consist of a multi-position switch, which is placed in the capsule in such a manner that it is accessible for operation.

    Abstract translation: 用于连接到电话设备的耳机，所述耳机包括具有内置接收器的胶囊，并且其上安装有具有麦克风的吊杆。 耳机通过具有相关插座连接的导线连接到电话设备，耳机具有用于麦克风和接收器的相关联的放大和调节电路，用于设置所述放大和调节电路的手动操作元件以及开关元件 用于切换部分地取决于电话设备中的麦克风的类型，部分地基于电话设备的麦克风和接收机线的极性。 放大和调整电路内置在耳机胶囊中，从而避免使用单独的连接盒，并且将手动操作元件放置在胶囊上。 开关元件由多位置开关组成，其以可操作的方式放置在胶囊中。

    Abstract: An earphone device (1) to be worn in the ear, which earphone device (1) comprising a main body (18) to be arranged in the concha (19) of the outer ear (14) of a user and an optical sensor (35), which optical sensor (35) comprises a light emitter (16) and a light detector (17). The earphone device (1) comprises window means (8, 9) through which light emitted by the light emitter (16) can be transmitted. The window means (8, 9) comprises an end face (31) adapted to abut a conchal wall (37) at a sensing position (36). The main body (18) comprises a speaker protrusion (26) to be inserted into to ear canal (15). The distance between the speaker protrusion (26) and the end face (31) is adjustable.

    Abstract: A method for attenuating undesired content in an audio signal and to an apparatus adapted to attenuate undesired content in an audio signal.The method has receiving an audio input signal (Si); providing a main audio signal (Sa) in dependence on the audio input signal (Si); determining an input level signal (Ln) indicating a signal level (Ln,i) of the main audio signal (Sa); applying a frequency-dependent gain to the main audio signal (Sa) to provide an audio output signal (So); providing an analysis signal (Sn) in dependence on the audio input signal (Si); determining a classification signal (Sc) indicating the presence in the analysis signal (Sn) determining a threshold control signal (St) indicating a frequency-dependent level threshold (72, 75, 76, Tf) for multiple frequency subbands; and determining the frequency-dependent gain in dependence on signal levels (Ln,i).
