Abstract: A data processing method for acoustic event includes: establishing a simulated acoustic frequency event module, a data capturing module, and a sound application decision module in a software manner, setting a simulated hardware parameter to the simulated acoustic frequency event module, inputting a sound signal to a frequency filtering module of the simulated acoustic frequency event module, and obtaining metadata from a frequency event quantizer of the simulated acoustic frequency event module, dividing each of the metadata into multiple frames according to a time interval by the data capturing module, accumulating an event number of each frame by the data capturing module, setting a label of each frame according to the event number, storing these frames, the event number and the label in a database, and training a decision model by the sound application decision module according to the database and a sound application.
