Using the psychoacoustic model, the input signal energy may be reduced in a manner that has little or no discernible effect on the quality of the audio being reproduced by the transducer. The psychoacoustic model selects energy to be reduced from the audio signal based, in part, on human auditory perceptions and/or speaker reproduction capability. The modification of energy levels in audio signals may be used to provide speaker protection functionality. For example, modified audio signals produced through the allocation of compensation coefficients may reduce excursion and displacement in a speaker; control temperature in a speaker; and/or reduce power in a speaker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Psychoacoustics for improved audio reproduction and speaker protection","description":"Psychoacoustic models may be applied to audio signals being reproduced by an audio speaker to reduce input signal energy applied to the audio transducer.
