Absolute Listening Tests-Further Progress

Document Thumbnail

The absolute listening method whereby there speakers are placed in an anechoic room and their outputs compared with their inputs, has been modified for use from room to room and for testing the interaction between speakers and their feed cables. In the basic method, signal is tapped off the terminal of the loudspeaker and listened to via good quality headphones, this signal is then compared with the output of an omnidirectional microphone placed in front of the speakers. Thus we can compare what goes into the speaker with what comes out of it. We can also compare the signal at each end of the speaker cable with the signal at the amplifier terminals and the acoustic output of the three speakers. Using a similar technique we can also hear the effect of different speaker cables on the signal at all three take off points: Amplifier, speaker input and output. Finally by placing the three speakers in real listening rooms we can compare the different effects that room loading has on the three speakers when auditioned against their input terminals and the dummy load. These results can be compared with those obtained in the anechoic room thus giving pointers to the speaker's - Room Interface Profile.
