Identify the correct sequence of average noise levels from the following sources in increasing order of their magnitude.

A typical office is the quietest source here at roughly fifty decibels of steady background noise.

Conversational speech sits a little higher, around sixty decibels.

A city street corner is busier and louder, near seventy to eighty decibels.

Highway traffic pushes the level higher still with dense fast moving vehicles.

Aircraft noise during take off is the loudest, reaching well past a hundred and twenty decibels.

The decibel scale is logarithmic, so each ten unit rise means ten times more sound intensity.
