Minimizing the damaging effects of loud music but with minimal reduction
in aesthetic quality of the music. When music presented through an audio is sampled
in order to determine average frequency, music having very low average frequencies
is predictably likely to be played louder than sampled music having higher average
frequencies. This unexpected observation is based upon a human factor, i.e. rock
and related music that is ordinarily composed and presented at relatively low frequencies,
e.g. 500 to 1000 Hz is likely to be played on the audio system at very high volume
because of the tastes of its listeners. An audio system for a data processor controlled
presentation of music with a set up for minimizing the damaging effects of loud
music comprising an implementation for predetermining a minimum average frequency
of music being presented in combination with measuring whether the music being
presented falls below said minimum average frequency for a sampling period. Then,
based on the above recognition, there is provided a device for automatically limiting
the music being presented to an audio volume below a predetermined level when said
measured average frequency for said sampling period is below said minimum average frequency.
