Loudness adjustment with self-adaptive gain offsets

摘要

A method for adjusting a loudness of an announcement sound signal relative to a loudness of an entertainment sound signal, the method comprising the following steps:
- determining the loudness of the entertainment sound signal, and
- adjusting the loudness of the announcement sound signal relative to the entertainment sound signal by determining a self-adaptive gain offset of the announcement sound signal relative to the entertainment sound signal, the self-adaptive gain offset adapting to the auditory perception of a user to which the entertainment sound signal and the announcement sound signal are output.
The method may be used in ear audio systems in combination with navigation systems. Thus, the audio system can learn from the volume settings made by the user.
