Abstract: Aspects of the subject technology provide for automatic adaptive noise cancellation, which may be provided with a substantially flat frequency response. In one or more implementations, a noise cancellation signal is combined with a pass-through audio signal with a ratio that is controlled based on a mixing curve. The mixing curve may be one of multiple mixing curves that are defined for multiple respective operational states of an electronic device.

Abstract: A method for preparing a bisphenol phosphate hydroxyl aluminum salt nucleating agent is provided, which adopts organic aluminum alcoholate as raw materials to prepare bisphenol phosphate hydroxyl aluminum salt. In prior art, a neutralization reaction of bisphenol phosphate and sodium hydroxide is firstly performed, so as to prepare bisphenol phosphate sodium salt; then a double decomposition reaction of sodium salt and inorganic aluminum salt is performed to prepare the bisphenol phosphate hydroxyl aluminum salt. The present invention combines the two-step reaction in prior art into the one-step reaction of phosphate and organic aluminum alcoholate for synthesizing the bisphenol phosphate hydroxyl aluminum salt, thereby simplifying the production process, improving the production efficiency, shortening the reaction time, and improving the product quality.
