Lion
A lion's roar reaches 114 decibels and carries up to 8 kilometres across the savannah. The Acoustic Wildlife Foundation ranks it among the most impressive vocalisations in the animal kingdom. This thunderous announcement serves to coordinate pride members and discourage territorial rivals.
The roar's frequency penetrates obstacles and induces primal fear in prey species. Scientists at the Edinburgh Centre for Intimidating Sounds confirm that even recorded lion roars elevate human heart rates significantly.
Toilet
The modern flush toilet produces approximately 75-85 decibels during operation. Whilst less powerful than a lion's roar, this sound occurs with far greater frequency in human experience. The Institute for Domestic Acoustics notes that toilet sounds carry particular psychological weight, often announcing one's presence in otherwise quiet households.
The distinctive gurgle of plumbing has inspired composers, frustrated light sleepers, and provided convenient cover for other bathroom acoustics since Victorian times.
VERDICT
The lion claims acoustic superiority through sheer volume and majesty. However, researchers note that toilet sounds, whilst quieter, occur approximately 2,500 times more frequently per human per year. The lion roars louder; the toilet roars more often.
