Abstract
In recent years, design engineers have begun to shift their efforts to achieve better sound in playback and/or reinforcement systems from further improvements int he audio components (microphones, amplifers, loudspeakers) to advances in the field of audio system equalization by the application of active or passive networks. It is where the frequency response of the sound system is shaped to compensate for the acoustic irregularities of the environment, that the most rewarding progress can be expected. Although the practice of equalizing peaks in the system reesponse with corresponding notch-filter networks is well-established and has been performed successfully for many years, new hardware and simplifed, more economical methods are required to make the often startling benefits of well-equalized sound available to a far larger number of audio systems, both old and new.
