The Loudest Sound in History: Unraveling the Krakatoa Eruption of 1883

The video tutorial explains the concept of decibels, starting with everyday sounds like breathing and rain, and moving to louder noises like vacuum cleaners and rock bands. It describes the logarithmic nature of the decibel scale, where each 10-decibel increase represents a tenfold increase in sound power. The tutorial warns about the dangers of high decibel levels, which can rupture eardrums and cause shock waves. It highlights the Krakatoa eruption in 1883, which produced the loudest sound in recorded history at 310 decibels, affecting global weather and causing tsunamis. The eruption's impact was felt worldwide, with pressure spikes and vivid sunsets.
