Abstract
The electro-acoustic response characteristic of digital cinema B-chain refers to the specific response of audio system to electrical signals within digital cinema.This article first elaborates the technical standards related to B-chain electro-acoustic response characteristics of digital cinema,followed with interpreting the essential technical articles in GY/T 312-2017 Cinematography—B-chain electro-acoustic reponse of motion-picture control rooms and indoor theatres—Specifications and measurements.The author also illustrates problems encountered during field calibrating and testing,and proposes an applicable measuring method for B-chain electro-acoustic response in digital cinema.The proposed method aims at providing requisite technical support for the calibration of digital cinemas,therefore advancing a positive and healthy development towards the overall sound reproduction technology within domestic digital cinemas.关键词
