Acoustic bulletin, Vol. 14 ¹ 2, (2011) |
| The paper deals with statistical analyzing of noise of knee joints using the cumulant analysis and orthogonal representations for probability density. For setting of the diagnostic signs for normal state and pathologies (fibrous or deforming arthrosis), the informativeness has been discovered for highest cumulant coefficients and probability density of the instant noise values (phonoarthogramms) and sound pressure levels. The analysis has been performed for both the overall length of noise records, and characteristic sectors. |
