Audio Quality Rating of Speaker-System by Digital-Filter Compensation
Ozora Furukawa (Shinshu Univ.), Kenji Furihata (信大)
Abstract (in Japanese) (See Japanese page) 
(in English) In this report, first, the combination of two small speakers (200Hz to 12.5kHz) and sub woofer (63Hz to 200Hz) system, and two big speakers (80kHz to 12.5kHz) were selected. Second, these digital filers were made in the detection limit of total harmonic distortion (63Hz to 10kHz).Third, the sound sources were made by convolution in these digital filters. Finally, these sources and the normal sources by each speaker-system were pared comparison about audio quality. As the results, it can be found that the two big speakers can improve audio quality by reproduction using amplitude compensation, and that the combination of two small speakers and sub woofer system cannot improve by only reproduction using amplitude compensation.
