Under ISO 23351-1 certification, yes — for the specific use case of speech privacy and cognitive focus work.

Many commercially renovated rooms achieve similar or lower performance in field conditions due to flanking sound paths through HVAC systems and structural elements that are not captured in panel-only laboratory ratings.
