HIGHKA pods achieve 35 dB noise reduction, certified to ISO 23351-1 Class A — the highest classification under the international standard for office pod acoustic performance. A well-constructed partitioned room with acoustic treatment will typically achieve higher absolute isolation than a pod. However, for the primary use cases that drive private space demand in open-plan offices — individual calls, video meetings, focused work, and small group discussions — ISO 23351-1 Class A performance (≥30 dB) is sufficient to provide functional speech privacy for all of these use cases, without the cost and permanence of construction.
