Støyfiguren

Støyfiguren is a term used in acoustics and audio engineering to describe a specific type of unwanted sound artifact. It refers to a distortion or alteration in the perceived sound that arises from the inherent noise floor of an audio system or recording medium. Unlike direct interference or unwanted external sounds, støyfiguren is an internal characteristic that can manifest as a subtle hiss, a buzzing, or a general muddiness in the audio signal, particularly in quiet passages or during periods of silence.

The presence of støyfiguren is often related to the quality of electronic components, such as amplifiers, preamplifiers, and digital-to-analog converters, as well as the limitations of analog recording media like magnetic tape. Thermal noise in resistors and semiconductor junctions are common sources of this internal noise. In digital audio, quantization noise and jitter can also contribute to støyfiguren. The perceived level of støyfiguren can be influenced by the dynamic range of the audio material; it becomes more noticeable when the desired audio signal is at a low amplitude, making the noise floor relatively more prominent.

Minimizing støyfiguren is a crucial aspect of high-fidelity audio reproduction and professional audio production. This is typically achieved through the use of high-quality, low-noise components, careful circuit design, and advanced noise reduction techniques. In digital audio, higher bit depths can reduce quantization noise, and robust clocking mechanisms can minimize jitter. Understanding støyfiguren is essential for engineers and audiophiles aiming to achieve the cleanest possible sound reproduction.
