What is indicated by a higher signal-to-noise (s/n) ratio?

A higher signal-to-noise ratio indicates better quality of sound or picture because it signifies that the level of the desired signal is significantly higher than the level of background noise. In audiovisual applications, a strong signal relative to the noise present means that the clarity and intelligibility of sound or picture are enhanced. This results in a more accurate representation of the original content, allowing for clearer audio playback and sharper visual imagery.

In practical terms, when the signal can be distinguished easily from the noise, the audience experiences a more enjoyable and immersive viewing or listening experience. This is particularly important in professional environments, where the quality of sound and picture can significantly impact communication and presentation effectiveness.
