I’m looking at acoustic pods and see “STC 30” and “STC 40.” What do these numbers mean for phone call privacy?
STC (Sound Transmission Class) measures how well a pod blocks sound. STC 30 means normal speech is not audible through the walls.
An office phone booth with STC 30±5 dB effectively blocks external noise, ensuring conversations remain confidential.
For HR-level confidentiality, look for pods that meet STC 40+, which blocks loud speech, or STC 50+, which is studio-grade. In Europe, look for Class A+ or Class B pods that ensure the highest level of speech privacy.
For conference rooms, dual silent ventilation systems maintain airflow without breaking soundproofing.
