The 122.4-dB shout is comparable in loudness to a chainsaw, a jet aircraft taking off, and an ambulance siren at close range.

History

Historical Context

In 2008 Alastair Galpin set the Guinness “loudest clap” at 113 dB, showing the franchise’s interest in acoustic extremes. Since Guinness shifted from book sales to paid publicity-driven record creation in 2008, it has tightened measurement rules, a trend that framed Joseph McGrail-Bateup’s 122.4-dB shout on 2 May 2026 in Canberra.
