Loudness of sound is measured in decibels(dB).
The Loudness target value is -10.3 LUFS.
Loudness range time series.
What is Loudness Normalization?
It is the point where the above"Content Loudness" becomes 0.
Loudness normalization is a function to make the volume of video constant.
The team also investigated how helmet angle and
wind speed affected the Loudness.
Using an oscilloscope, we can compare the pitch and Loudness of different waves.
With this, you may need more energy or Loudness to hear a sound more clearly.
Parameters for calculating the Loudness Range of EBU TECH 3342 are
Absolute Threshold -70 LKFS and Relative Threshold -20 dB.
Right click on a YouTube video and the content Loudness seen from the
detailed statistical information is equivalent to Loudness- Target.
The muffler is engineered as an acoustic device to reduce the Loudness of the sound pressure created by the engine by acoustic quieting.
It is important to add that this relative Loudness can be eliminated by lowering the suction power,
since of course we can do this through the telephone application.
The short-term Loudness parameter of EBU TECH 3341 has a window length of 3 seconds
and an overlap length of 2.9 seconds or more(overlap ratio is 96.7% or more).
Signals in the 2- 4-kHz octave sound loudest, and the Loudness of other frequencies drops increasingly,
depending both on the distance from the peak-sensitivity area and on the level.
The Loudness normalization on YouTube is done in a way that the
Loudness of the sound source is adjusted to the Loudness target value as much as possible within the range
where the peak does not clip.
