Yes — in standard office environments. HIGHKA’s bidirectional acoustic structure reduces outgoing speech (typically 55–65 dB at the speaker’s mouth) by 35 dB before it reaches the open floor. At a distance of 1–2 metres from the pod, the residual sound level is below the typical open-plan ambient noise floor and is not intelligible as speech to colleagues. Both ISO 23351-1 Class A certification and the bidirectional patent-protected structure provide the technical basis for this guarantee.
