The atmosphere at the national stadium reached 100dB when Scott McTominay's name was announced, a noise level similar to a jackhammer.
When the teams came out, the noise reached ambulance siren levels of 115dB.
Levels peaked during the national anthem, Flower of Scotland, reaching 121db, which is equivalent to a jet engine.
