AI Technical Summary

Problems solved by technology

However, this solution is not preferred for users who wish to control the volume themselves
Also, simply limiting the electrical output power of an audio player is likely to be ineffective for different headphones with different sensitivities (defined as the sound pressure level produced at a specific power input)
In fact, since hearing loss is related to output sound pressure level and listening time, limiting the output electrical power of audio players cannot be directly related to preventing hearing damage or loss

Abstract

Techniques and apparatus for limiting a sound pressure level produced by an audio output device driven by an audio player. During play, the audio player monitors the current sound pressure level of the audio output device, and in response thereto limits the sound pressure level by controlling an output level of audio signals it generates so as to reduce hearing loss caused by excess volume.

Description
