BARRIER INSERTION LOSS

This spreadsheet determines the insertion loss for outdoor barriers.
Enter distances in cells D6 thru D9:

Enter the barrier height:                                         feet
Enter the barrier width:                                          feet
Distance from source to barrier:                                  feet
Distance from barrier to receiver:                                feet

Distance between source and receiver:                                          0.0   feet
Sound path length over barrier:                                                0.0   feet
Sound path length around barrier:                                              0.0   feet
Difference in sound path length over barrier:                                  0.0   feet
Difference in sound path length around barrier:                                0.0   feet
