摘要： A damping system for an ear cup headphone design. The damping system introduces a completely enclosed inner acoustic volume in the rear volume of the ear cup by way of supporting a baffle damper spaced apart from the driver of the ear cup, wherein the density of the baffle damper diffuses acoustic wave rearwardly emanating from the driver. Additional damper masses of different relative densities may occupy the rear volume rearward of baffle damper.

摘要： Headphone systems and methods are provided to mitigate the impact of wind on active noise cancellation. At least one headphone system includes an earpiece with a speaker to convert a signal into acoustic energy in an acoustic volume. A microphone is acoustically coupled to an external environment and detects external noise. A control circuit is configured to detect wind and to adjust a feed-forward audio signal from the microphone based on the wind detection.

摘要： An arrangement comprising an ultrasonic transducer and a damping element with a longitudinal axis, which damping element connects the ultrasonic transducer with a housing- or measuring tube wall. The transducer has an end piece with a medium-contacting surface, from which ultrasonic signals are transferred into a gaseous or liquid medium. The damping element has at least two annular grooves and an annular mass segment arranged therebetween, characterized in that the damping element has a first eigenfrequency, in which the annular mass segment executes an axial movement parallel to the longitudinal direction of the damping element. This first eigenfrequency is the highest eigenfrequency, in the case that a plurality of eigenfrequencies are present, in the case of which the annular mass segment executes an axial movement parallel to the longitudinal direction of the damping element, and the damping element has a second eigenfrequency, in which the annular mass segment executes a rotary movement. This second eigenfrequency is the lowest eigenfrequency, in the case that a plurality of eigenfrequencies are present, in the case of which the annular mass segment executes a rotary movement, will and wherein the ratio of the first eigenfrequency to the second eigenfrequency is less than 0.75; and a field device of process measurements technology.

摘要： Systems and apparatuses are described to automatically balance acoustic channel sensitivity. A computer readable medium containing executable computer program instructions, which when executed by an acoustic signal processing system, cause the acoustic signal processing system to perform a process that includes calculating a long-term power level of a main acoustic signal to obtain an averaged main acoustic signal. Segments of the main acoustic signal are excluded from the averaged main acoustic signal using a desired voice activity detection signal. A long-term power level of a reference acoustic signal is calculated to obtain, an averaged reference acoustic signal. Segments of the reference acoustic signal are excluded from the averaged reference acoustic signal using the desired voice activity detection signal. An amplitude correction signal is created using the averaged main acoustic signal and the averaged reference acoustic signal. The amplitude correction signal is used to adjust either the main acoustic signal or the reference acoustic signal to automatically balance acoustic channel sensitivity.

摘要： A system for noise removal is coupled to a signal unit that provides a digital signal. The noise removal system includes a transformation module to transform the digital signal into an f-digital signal, a threshold filter to generate a noiseless signal from the f-digital signal based on a threshold profile, and a signal synthesizer to provide a gain to the noiseless signal and to transform the noiseless signal into an output signal.
