Crosstalk measurement is made on audio systems to determine the amount of signal leaking across from one channel to another. Interchannel crosstalk applies between the two channels of a stereo system, and is usually not very important on modern systems, though it was hard to keep below the desired figure of -30dB or so on vinyl recordings and FM radio. Crosstalk between channels in mixing consoles, and between studio feeds is much more of a problem, as these are likely to be carrying very different programmes or material. The IBA drew up a weighting curve for use in crosstalk measurement that gives due emphasis to the subjective audibility of different frequencies, as shown here. This is still in use, despite the demise of the IBA, and in the absence of any international standards is worth adopting.
AI shoe structure generation design method based on feature decoupling and topology preservation
PendingCN122366151ATopological consistencyCrosstalk measurement
The application discloses an AI shoe structure generation design method based on feature decoupling and topology maintenance, relates to the technical field of digital manufacturing, and comprises the following steps: constructing condition control parameters according to crosstalk measurement parameters, and performing topology consistency measurement on a structure state constrained by the condition control parameters to generate a topology risk field map; evaluating the risk level of the topology risk field map, freezing high-risk areas on the topology risk field map, generating a local structure freezing mask and a freezing curve index set, performing selected area consistency write-back processing and process constraint checking on the local structure freezing mask and the freezing curve index set, and outputting a manufacturable material mapping table. The application synchronously generates a topology risk field map by calculating crosstalk measurement parameters, quantitatively predicts potential influences of style creativity on structure integrity, and realizes end-to-end connection from digital space risk evaluation to manufacturing constraints in the physical world.
