What is the bandwidth of the full-audio left and right channels in Dolby surround sound?

The correct answer indicates that the bandwidth of the full-audio left and right channels in Dolby surround sound covers the range of 20 Hz to 20,000 Hz. This range is significant because it encompasses the full spectrum of human hearing. The lower limit of 20 Hz corresponds to the lower threshold of audibility, while the upper limit of 20,000 Hz represents the higher end of human hearing capability in young individuals.

In the context of Dolby surround sound, this full bandwidth is essential for accurately reproducing a wide array of audio frequencies, from deep bass notes to high-frequency sounds, allowing for a more immersive experience. This ensures that both music and sound effects are rendered with clarity and depth, contributing to the realism and richness of the listening experience.

Thus, the choice of 20-20,000 Hz is aligned with industry standards for high-fidelity audio, confirming the capability of Dolby surround sound systems to deliver comprehensive and high-quality audio performance to listeners.
