SMPTE Creates A New Technology Committee
The Society of Motion Picture and Television Engineers (SMPTE), have announced the creation of a new technology committee, TC-25CSS, dedicated to cinema sound.
The committee will work to update SMPTE standards and recommended practices to address opportunities created by the many technical advances since standards last were created, as well as to improve the quality and consistency of cinema sound.
"Improvements in measurement technology, digital sound delivery, and in sound reproduction equipment, as well as the greater detail and dynamic range of movie soundtracks, present a variety of challenges in providing quality cinema sound," said Brian Vessa, executive director of digital audio mastering at Sony Pictures Entertainment and chair of the new SMPTE committee.
"Existing SMPTE standards and recommended practices help to minimize variations, but cinema sound quality today is highly dependent on the skill, talent, training, and hearing acuity of the adjusting technician," added Vessa. "TC-25CSS, the first SMPTE technology committee dedicated solely to cinema sound, will explore and standardize new sound measurement techniques with the goal of consistency in sound reproduction between the mixing stage and diverse cinema spaces."
TC-25CSS was formed following an extensive study by the Theater B-Chain Study Group, which conducted tests of current test equipment and methods, measured reference and commercial theaters, and collaborated on observations and results. The committee currently has 130 members, representing more than 90 companies and academic institutions from 14 countries.
"The introduction of Digital Cinema is helping to provide a consistently high quality of image display. Sound is at least as important in the movie theater experience," said Hans Hoffmann, head of production technology for the EBU and SMPTE standards vice president. "The Cinema Sound Systems committee will work to ensure that the latest science and technology are used to allow cinema-goers to enjoy the full impact of the sound experience as created in the mixing room."
As TC-25CSS works to standardize techniques and tools for optimizing sound systems and theater acoustics, the committee will correlate human sound perception with the science of sound reproduction and measurements as the underlying principle. Current activities include development of a recommended practice for measurement and calibration of B-chain sound systems using modern standards and measurement technology, creation of a standard pink noise test signal, a final report on data and findings from the Theater B-Chain Study Group, and work by two new study groups examining immersive audio systems and new electroacoustic measurement methods and target curves.
In the upcoming SMPTE Standards Webcast "Cinema Sound Systems — Raising the Bar Through New Standards," scheduled for March 12, Vessa will discuss topics including current SMPTE standards, the new committee's work, and the impact of new and emerging immersive cinema sound systems on the standards-creation process. The webcast is free and open to all.
