Abstract: A method for diagnosing sealing properties of microphone and/or loudspeaker seals in an electronic device. Sealing properties of the microphone and/or loudspeaker seals are diagnosed by comparing a representation of a total impulse response signal associated with certain stimuli with a representation of a predetermined reference total impulse response signal associated with the electronic device.

Abstract: A method for adapting a characteristic of an audible signal produced by a portable communication device includes obtaining a measure of the normal conditions in the environment surrounding the device. The method also includes obtaining at least one measure from a sensor on the portable communication device as a response to an audible event, where the measure corresponds to the current condition in the environment surrounding the device. The method further includes adapting a characteristic of the audible signal based on the relationship between the current condition and the normal condition and presenting the audible signal to a user of the portable communication device.

Abstract: A device may include logic configured to detect information about a condition of a speaker in a communications device. The logic may process the information, load equalization logic based on the processed information, and may apply the equalization logic to an input signal of the speaker when the information indicates that a frequency response for the speaker should be changed.
