basfrekvensfällan
Basfrekvensfällan refers to a phenomenon observed in the perception of sound, particularly in music and audio engineering. It describes a situation where the perceived fundamental frequency of a complex sound is lower than the actual lowest frequency present in the sound wave. This can occur when the fundamental frequency is missing but its harmonics are present in a way that the human auditory system still infers the presence of the fundamental. For example, a musical note might be played where the true lowest frequency is absent, but the overtones (harmonics) are present, and the brain reconstructs the missing fundamental.
This effect is a testament to how our auditory system processes sound, relying on pattern recognition and
