Bedroom  30 -  35 dB
Public Library      40 -  45 dB
Urban Neighborhood   50 -  55 dB
Industrial Area     60 -  70 dB
Busy Street    70 -  80 dB

Noise Level

By subtracting the common indoor noise level from the  Outdoor noise level  YOU can estimate the appropriate  acoustic performance you need for your windows.
For example:

Difference = 36 dB
