Problems solved by technology

[0003] When the range hood is used for a period of time, it is inevitable that the state of the range hood will change due to many external factors such as the deposition of oil fume, which will lead to changes in the noise characteristics of the range hood. When the target sound changes , while the control sound remains unchanged, the masking effect of the control sound will be weakened, and the annoyance of the superimposed sound will increase, thus affecting the effect of the audio injection function

Abstract

The embodiment of the invention discloses an audio injection updating method, a control device and an audio injection extractor hood, the updating method is applied to audio injection updating of the extractor hood in the use stage, and the updating method comprises the following steps: acquiring working noise of the extractor hood under different gears when the audio injection is started; comparing the annoyance degree of the working noise with the annoyance degree of the last working noise, determining a final regulation and control sound according to a difference value between the annoyance degree of the working noise and the annoyance degree of the last working noise, and performing audio injection updating on the last regulation and control sound of the range hood under different gears by using the final regulation and control sound. The self-checking configuration updating of the audio injection function is completed, self-adaptive optimization of the regulation sound is realized, the audio injection function is played, the hearing feeling of a user is effectively improved, the service life of the audio injection function is prolonged, and the effect of the audio injection function is perfectly played.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of audio injection, and in particular to an audio injection update method, a control device, and an audio injection range hood. Background technique [0002] A method of injecting audible sound into the original noise (target sound) to change its auditory properties is called audio injection. The added sound is called the modulation sound, and the mixed sound is called the superimposed sound. The purpose of audio injection is usually to reduce the annoyance of the target sound. Compared with the traditional subtractive control strategy, the audio injection method has the advantages of simple implementation, low cost, and easy engineering implementation. It has gradually become a frontier topic in the field of noise control, and has attracted extensive attention and attention from researchers and industries. The study found that the "cancellation effect" and "constructive effect" o...
