As we navigate 2026, the audio frequency spectrum has evolved from a static 20 Hz to 20 kHz reference into a dynamic landscape shaped by AI-driven sound profiles and immersive spatial audio standards.

EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17-mm-thick (0.6-in) layer can ...

Humans can observe what and where something happens around them with their hearing, as long as sound frequencies lie between 20 Hz and 20 000 Hz. Researchers have now developed a new audio technique ...
