In a standard office (60–65 dB ambient), DS,A = 29.4 dB brings the pod interior to approximately 31–36 dB — near silence. In a typical conference hall (85–95 dB ambient), the same 29.4 dB reduction brings the interior to approximately 56–66 dB — a normal conversational ambient. The pod delivers the same acoustic isolation regardless of environment; the result inside the pod differs because the starting ambient differs. In both cases, the interior reaches the level at which normal-volume conversation is possible without strain — which is the functional requirement in both settings.
