97 results about "Vocal intensity" patented technology

Vocal intensity occurs at all volumes from very soft (ppp) to very loud (fff). Vocal intensity is never the result of a pushed voice; intensity is the result of a BALANCED voice.

Acoustic imaging method

ActiveCN112017688AThe result is accurateDoes not cause large differences in intensity distribution resultsSpeech analysisDistribution matrixSound sources
The invention relates to an acoustic imaging method, which solves the problems that general noise detection needs large computing power and cannot be adjusted to adapt to systems with different computing power conditions. The method comprises the following steps of: acquiring original audio data through a microphone; performing data processing on the original audio data to obtain a sound source intensity distribution diagram; collecting image information through a camera; and fusing the sound source intensity distribution diagram with the image information to obtain an acoustic imaging picture. The beneficial effects of the invention are that: the method achieves the visualization and materialization of the sound intensity through the combination of the sound source intensity distributiondiagram and the photographed image; a correction matrix is adopted to calibrate and correct the calculation deviation of the sound source intensity distribution matrix, and unnecessary interference iseliminated, so that the result is more precise; high-power interpolation processing is carried out after FFT processing, so that the computing power pressure is reduced, and meanwhile, the resolutionratio is also ensured; the simplified and optimized process can also be realized by using a small and light carrier device, and can be suitable for more application scenes.
