Equalization Simplified
AES Convention 49 · Paper 984 · September 1974
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 in the audio components (microphones, amplifiers, speakers) to advances in the field of audio system equalization by the application of active or passive networks. It is here, 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 response with corresponding notch-filters networks is well-established and has been performed successfully for many years, new hardware and simplified, 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.
