BS.1770

BS.1770 is a technical standard created by the European Broadcasting Union that helps measure the loudness of audio signals, like TV shows or music, across different platforms. It ensures consistent sound levels, so viewers don’t experience sudden loud or quiet moments. The standard achieves this by analyzing audio to calculate a perceived loudness, accounting for how humans perceive sound. Broadcast and streaming services use BS.1770 to normalize audio levels, providing a more uniform listening experience without the need for constant volume adjustments.
