Abstract
Methods and apparatuses for user sound exposure limiting are disclosed. In one example, an accumulated sound dose exposure from a headset speaker is determined for a plurality of sequentially monitored time intervals during a current listening session, wherein the current listening session comprises a total session time. It is determined whether a predicted sound dose exposure for the total session time exceeds or falls below a permitted sound dose exposure limit, the predicted sound dose exposure determined from the accumulated sound dose exposure. A threshold intervention level at which a time-weighted-average limiter at a headset applies attenuation to an audio signal output at a headset speaker is adjusted.
