Abstract: Methods and apparatus are provided for automatically adjusting, by an audio device, the SPL of its audio output. As described herein, the SPL is adjusted based on detected ambient noise. According to aspects, audio device iteratively adjusts the SPL based on the ambient noise. According to aspects, the SPL is adjusted to be greater than the ambient noise by a threshold SPL amount. According to aspects, the audio device outputs sound in substantially a first direction and the microphone detects sound substantially outside of the first direction. The adjusted sounds are output by the audio device.

Abstract: This document describes a method that includes receiving a driver signal for an acoustic transducer of an acoustic device. The method also includes receiving a signal from a microphone of the acoustic device, and, processing the driver signal through a filter to provide a reference signal. The filter has a transfer function associated with a condition of the acoustic device. The method also includes comparing the signal to the reference signal to determine whether the signal has a threshold similarity to the reference signal, and, indicating the condition of the acoustic device in respond to the determined threshold similarity.
