Evaluation of a new speech privacy quick test for enclosed rooms
Keywords:
Best fit, Quick tests, Room absorption, Speech privacy, Weak pointsAbstract
The E2638 procedure can identify weak points in the room sound insulation and can give an accurate rating of the overall speech privacy provided by the room. In some cases a simpler and quicker test, that could evaluate particular problems, would be more helpful. There is little scatter about the best fit line and the range of mean differences between these two quantities is again less than 2 dB over a wide range of room absorptions. The LD(f) values from the QT procedure diverged from the other results with the differences increasing with increasing frequency. When using the OMNT source, the QT results varied in a manner approximately parallel to the E2638 results.
