5.1.1 Data compression
With this, digital radio takes advantage of the properties of human hearing.
The human ear does not perceive sounds which are found under a specific
minimum volume. Data which are found under the so-called audibility
threshold can, therefore, be filtered out. This is possible because, in a
digital data stream, the relevant relative volume for other units is saved for
every unit of information. Moreover, in an audio signal, the quieter parts
are superimposed by louder ones at a specific limit value. All the sound
information below the threshold of hearing in a piece of music can be
filtered out of the signal to be broadcast. This leads to a reduction of data
