Dynamics Distortion: Loudspeaker Sensitivity Modulation Generated by Audio Signals

Understanding heat production in moving-coil loudspeakers has allowed for using designs and materials that prevent the physical damage due to high temperatures. However, when high power bursts increase voice-coil temperature, the loudspeaker experiences power compression, reducing the effective sensitivity and changing the frequency response and damping. Working with music signals, after a sudden increase in applied power, the sound level fades as temperature rises, possibly affecting the listener's experience.
