| 4. Theory The SPL is related to the sound power level (SWL), the directivity Qq, of the j th source, the absorption of the room, the distance of the j th source from the receiver rj from j=1 to n in equation (1) given by McNulty[5] as: |
 |
| where detailed terms are given in the paper. For a single source and receiver, equation (1) can be reduced to its familiar form as in (2) below: |
