This project investigates a novel method of assessing the low frequency quality of loudspeakers during music reproduction; the work is focussed on professional applications such as mix monitoring in recording studios where replay becomes a matter of absolute accuracy rather than subjective preference.
Early results indicate that the method, based on the Modulation Transfer Function (MTF), might be a useful indicator of subjective quality. Several 'virtual' loudspeaker models with differing low-frequency reproduction characteristics have been simulated using digital signal processing; subjective ratings to evaluate the low-frequency reproduction quality of these models are being obtained through carefully controlled listening tests and the results compared to objective MTF data generated for each model.
