A method and system for heterogeneous event detection. Sensor data is obtained and divided into discrete data windows. Each data window is defined by and corresponds to a time period of the sensor data. A time-frequency representation over the time period is calculated for each data window. A filter mask is calculated based on the data window corresponding to the time-frequency representation. The filter mask is applied for reverting the time-frequency representation to a time representation, resulting in filtered data. Features, such as extrema or other inflection points, are identified in the filtered data. The features define events, and transforming the time-frequency representation back into the time domain emphasizes differences between more and less prominent frequencies, facilitating identification of heterogeneous events. The method and system may be applied to body movements of people or animals, automaton movement, audio signals, light intensity, or any suitable time-dependent variable.

Embodiments herein relate to systems, devices and methods for fitting hearing assistance devices. In a first aspect, a method of fitting a hearing assistance device is included, the method including providing an audio sample to a hearing assistance device wearer, receiving input from the hearing assistance device wearer regarding a preferred sound volume or perceived loudness, receiving input from the hearing assistance device wearer with the external device regarding a bass/treble balance, and determining a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL). Other embodiments are also included herein.

To provide improved feedback reduction in hearing assistance devices, technical solutions described herein include remeasuring a feedback path and updating adaptive feedback cancellation parameters whenever a user receives and plays an audio stream signal. When the user converts the audio stream signal into an acoustic audio signal using a speaker within the hearing assistance device, a feedback portion of the acoustic audio signal may be fed back into the microphone of the hearing assistance device. The hearing assistance device can then compare the feedback portion to the received audio stream signal, and that comparison can be used to update adaptive feedback cancellation parameters within the hearing assistance device. When the hearing assistance device receives an acoustic audio input at the microphone, it may amplify that input and apply the received acoustic audio input based on the updated adaptive feedback cancellation parameters to reduce or minimize feedback.
