Matalataajuiset

Matalataajuiset is a Finnish term used to describe phenomena, devices, or signals that operate at or convey content in the low-frequency part of the spectrum. The word is formed from matala ("low") and taajuus ("frequency"), with the adjectival suffix -iset indicating a class or category. In practice, the precise meaning of “matalataajuiset” depends on the field and context.

In audio and acoustics, matalataajuiset often refers to bass and sub-bass content, typically from a few tens of hertz up to a few hundred hertz. In electronics and telecommunications, it can denote systems that use low-frequency bands or long-wavelength signals, such as sensor channels or transmission schemes that rely on lower carrier frequencies. In seismology and structural engineering, the term can describe long-period signals and vibrations, where the dominant motion occurs over seconds or longer.

Usage and interpretation: because there is no universal threshold, professionals define “matalataajuiset” relative to their discipline’s standard frequency ranges. The term is common in Finnish-language technical literature, product descriptions, and educational materials, and it appears in discussions of loudspeakers, subwoofers, filters, and vibration analysis.
