Acoustician Jukka Pätynen stands in an anechoic space, designed so that no surface reflects sound. Hard foam wedges cover the walls to absorb any incident sound; the room itself is a box within a box, with the inner space floating on elastic materials for vibration isolation. “On the decibel scale, 0 dB is the lower limit of human hearing,” says Pätynen. “Our calculations suggest that the actual background noise [in the room] could be as quiet as −10 dB.” (Nature | 2 min read) (Jarkko Mikkonen for Nature)
