The THX sound system has been a benchmark for high-quality audio in cinemas and homes for decades. The distinctive “Deep Note” sound that precedes THX-certified movies is instantly recognizable, and the company’s logo has become synonymous with exceptional audio fidelity. But have you ever wondered who invented THX sound? In this article, we’ll delve into the fascinating story of THX’s origins and the innovative minds behind its creation.
A Brief History of THX
THX Ltd. was founded in 1983 by George Lucas, the legendary filmmaker behind the Star Wars franchise. Lucas was driven by a passion for creating immersive cinematic experiences, and he recognized the importance of high-quality audio in achieving this goal. At the time, movie theaters were plagued by poor sound systems, which often resulted in distorted or muffled audio. Lucas wanted to change this, and he assembled a team of experts to develop a new sound system that would revolutionize the film industry.
The THX Team
The THX team was led by Tomlinson Holman, a renowned audio engineer and inventor. Holman is often credited as the “father of THX” due to his instrumental role in developing the company’s sound system. He worked closely with Lucas and other experts to design and test the THX system, which was initially called “THX Sound System.”
Other key members of the THX team included:
- James A. Moorer: A computer scientist and audio engineer who developed the THX Sound System’s digital signal processing algorithms.
- John L. Chalker: An audio engineer who contributed to the design of the THX Sound System’s loudspeakers and amplifiers.
- Tomlinson Holman’s team at Lucasfilm: A group of talented engineers and technicians who worked tirelessly to develop and refine the THX Sound System.
The Development of THX Sound
The development of THX sound was a complex and challenging process. The team faced numerous technical hurdles, including the need to create a sound system that could accurately reproduce the full range of human hearing (20 Hz to 20 kHz). They also had to design a system that could handle the high sound pressure levels required for cinematic applications.
To overcome these challenges, the THX team employed a range of innovative technologies, including:
- Digital signal processing: The THX Sound System used digital signal processing algorithms to optimize audio quality and reduce distortion.
- High-power amplifiers: The team developed high-power amplifiers that could handle the high sound pressure levels required for cinematic applications.
- Custom-designed loudspeakers: The THX team designed and built custom loudspeakers that were optimized for cinematic applications.
The “Deep Note” Sound
One of the most distinctive features of the THX Sound System is the “Deep Note” sound that precedes THX-certified movies. This sound is a low-frequency tone that is designed to test the audio system’s ability to reproduce low frequencies. The “Deep Note” sound was created by James A. Moorer, who used a combination of mathematical algorithms and audio processing techniques to generate the sound.
THX Certification
In addition to developing the THX Sound System, the company also established a certification program for cinemas and home theaters. The THX certification program ensures that audio systems meet the company’s strict standards for audio quality and performance.
To become THX-certified, a cinema or home theater must meet a range of technical requirements, including:
- Audio frequency response: The system must be able to accurately reproduce the full range of human hearing (20 Hz to 20 kHz).
- Sound pressure level: The system must be able to handle high sound pressure levels without distorting or compromising audio quality.
- Signal-to-noise ratio: The system must have a high signal-to-noise ratio to ensure that audio signals are clear and free from background noise.
THX Certification Levels
THX offers several certification levels for cinemas and home theaters, including:
- THX Certified Cinema: This certification level is designed for commercial cinemas and ensures that the audio system meets THX’s strict standards for audio quality and performance.
- THX Certified Home Theater: This certification level is designed for home theaters and ensures that the audio system meets THX’s standards for audio quality and performance.
- THX Certified Select: This certification level is designed for home theaters with smaller screens (up to 40 inches) and ensures that the audio system meets THX’s standards for audio quality and performance.
Legacy of THX Sound
The THX Sound System has had a profound impact on the film industry and beyond. The company’s innovative approach to audio design and certification has raised the bar for audio quality in cinemas and homes around the world.
Today, THX is a leading provider of audio technologies and certification programs for the film, music, and gaming industries. The company continues to innovate and push the boundaries of audio technology, ensuring that audiences around the world can enjoy immersive and engaging audio experiences.
