You live on a busy street, but as a music lover, you want to reduce the traffic noise. If you install special sound-reflecting windows that reduce the sound intensity level by 35.0 dB , by what factor have you reduced the sound intensity? If, instead, you reduce the intensity by half, what change (in dB) do you make in the sound intensity level?
