The bass traps seem annoying as fuck to calculate but he claims he has a STC of 90, with an effectiveness down to 30HZ, seems kinda bullshit.

Acoustic impedance is the term used to describe the resistance to passage of ultrasound energy through a substance or tissue (see Table 1). Acoustic impedance (Z) is dependent on tissue density (ρ) in kg/m 3 and speed of the sound wave in that tissue (c) in m/s. Z = ρ. c
