distortionszonen

Distortionszonen is a term used in several technical disciplines to denote regions where distortions of a signal, image, or measurement become pronounced. The concept encompasses areas in input space, physical space, or data space where nonlinearity, sampling limits, aberrations, or other imperfections cause deviations from an ideal representation.

In acoustics and audio engineering, distortionszonen refer to the ranges of amplitude, frequency, or time where loudspeakers, amplifiers, or transducers introduce noticeable distortion. These zones often arise from component nonlinearities, clipping, or saturation, and they degrade accuracy, timbre, and intelligibility.

In optics and imaging, distortionszonen describe areas affected by lens aberrations, geometric distortion, chromatic aberration, or sensor nonuniformity. Such zones can appear at the periphery of an image, in regions with steep depth variations, or where the optical path encounters irregularities, leading to blurred or displaced features.

In measurement and signal processing, distortionszonen indicate parts of a signal or dataset where quantization, sampling, or demodulation errors accumulate. Detection and characterization typically involve distortion metrics, calibration scans, or mapping procedures that identify and quantify these zones.

Detection and mitigation share common strategies: operating systems within their linear or nominal ranges, applying predistortion or calibration corrections, and using higher-quality components or algorithms to reduce the extent and impact of distortionszonen. The concept is useful in design, testing, and quality assurance across audio, optical, and measurement domains. See also distortion, nonlinearity, optical aberration, lens distortion, calibration.
