Audio Loudness (LUFS)
Loudness Units Full Scale (LUFS) is a standard measure of perceived audio loudness. Ensuring loudness consistency is critical for user experience across different platforms and ads. It's measured in LUFS, where -23 is a commonly accepted value for TV commercials. Some platforms may allow -14 LUFS to grab attention.
Why do we test it?
Excessive loudness can irritate users, while audio that is too quiet may go unnoticed. The loudness test ensures that the ad's audio stays within acceptable loudness levels, preventing potential rejection from ad networks that enforce loudness standards. This helps to maintain consistency, ensuring your ad sounds professional and isn't disruptive to users.
