Abstract
Devices for monitoring a sound pressure level of sound generated by a speaker. For example, the device may sample voltages at various points along a path of an audio signal, determine a current associated with the audio signal, and receive or infer an efficiency of the speaker. The device may then determine the sound pressure level based on the voltage, the current, and the efficiency to more accurately monitor the sound pressure level exposure of a user.
