Abstract: Systems and methods for self-administering a sound test to verify operation of a speaker and/or alarm within a hazard detection system are described herein. The sound test can verify that the audible sources such as the alarm and speaker operate at the requisite loudness and frequencies. In addition, the sound test can be self-administered in that it does not require the presence of a person to initiate or verify that the audible sources are functioning properly.

Abstract: The subject matter described herein provides systems and techniques for filtering an audio signal using active noise cancellation (ANC). A channel response finite impulse response (CR FIR) filter in a conventional ANC system may be replaced with a two filter cascade configuration. The first filter in the cascade filter configuration may be a CR FIR filter with interleaved zero coefficients and the second filter may be a response interpolator filter that is a fixed interpolator. The CR FIR filter in the two filter cascade may be adaptive and may have its non-zero coefficients tracked, updated, adapted, and/or computed. The fixed interpolator in the two filter cascade may be fixed and therefore non-adaptive. The channel frequency response profile of the two filter cascade configuration may be similar to the channel frequency response profile of the conventional CR FIR filter that the cascade filter configuration replaces.
