3. Overall performance
The demonstration out-of private parameters comes after the transaction given for the (4). Note that new boxes demonstrated in all rates correspond to new may include this new 25th and you can 75th percentile; the black dot means this new average and the whiskers match ±step 1.5 inter-quartile assortment; research over otherwise lower than so it range is outliers as they are illustrated as the circumstances regarding graph. Hardly any cases of tall outliers was basically got rid of.
Shape cuatro suggests the outcomes of your own spectral level regularity regarding the fresh burst used in Standard Gloss (SP) and brand new variation (NV) out of /?/ along with new spectral include 20 in order to 11 Zibo girl dating marriage,one hundred thousand Hz.
The results demonstrate that this new spectral peak frequency is significantly large throughout the brand new variant than in Important Polish both for /?/ and you may (/?/: NV 5,490 Hz vs. SP cuatro,176 Hz, t=8.024, p : NV 5,546 Hz vs. SP 4,164 Hz, t=6.706, p
Package plots for regularity out of spectral highs off /?/ so when pronounced when you look at the Basic Polish plus the brand new variation.
Container plots of land to own center out-of the law of gravity (top) and you may fundamental departure (bottom) from /?/ and as noticable when you look at the Simple Polish along with the variation
Container plots of land to possess skewness (top) and you may kurtosis (bottom) from /?/ so that as obvious within the Practical Shine plus in the new variant.
The newest centre regarding gravity thinking off /?/ and you will was in fact notably highest regarding the brand new variant compared to Practical Shine (/?/: NV 5,367 Hz compared to. SP cuatro,375 Hz, t=5.327, p : NV 5,205 Hz compared to. SP cuatro,468 Hz, t=step 3.894, p showed significantly straight down skewness opinions than its Important Shine relevant avenues (/?/: NV ?0.079 versus. SP 0.338, t=?dos.050, p=.06 (at the quantity of analytical inclination) : NV ?0.317 versus. SP 0.179, t=?2.822, p is proper-skewed compared with brand new spectra of one’s the new versions hence try skewed left. Kurtosis wasn’t notably different in SP in addition to NV.
Field plots of land on the spectral hill tips m1 (top) and you may m2 (bottom) away from /?/ so when made in Important Polish as well as in new variant.
Contour seven shows the results into the two spectral slopes m1 and you can m2 for both /?/ plus Standard Shine plus in the variant.
The two steps m1 and you will m2 of the regression outlines out of frication spectra are useful in identifying the product quality Polish and you may the new variants out of /?/ and you will . The first regression range mountain (m1) of are significantly lower in the newest variant than in Important Polish ( : NV 1.31 dB/kHz2 vs. SP 2.51 dB/ kHz2, t=?2.348, p
Standard Shine variation (/?/: NV ?4.76 dB/kHz2 vs. SP ?cuatro.cuatro dB/kHz2, t=?step 3.738, p : NV ?4.91 dB/kHz2 against. SP ?cuatro.6 dB/kHz2, t=?4.623, p this new spectral hill was somewhat straight down towards the the new variant compared to the Simple Gloss to the frequency cover anything from five hundred Hz to 5,000 Hz (m1). To the high frequency vary from 5,000 Hz to eleven,000 Hz, each other /?/ and have a notably steeper spectral decrease to the the brand new variant versus Important Gloss, With the rise/fall of your regression range, a top (positive) value to have m1 function an excellent steeper increase of one’s regression line, while getting m2, a lower life expectancy (negative) well worth corresponds to a great steeper slip of your regression range, both in regard to its respective regularity selections regarding the Power (Spectral Density) spectra. These devices dB/kHz2 is a result of new computation of mountain of regression line: m= (y2?y1)/(x2?x1) with y=(dB/kHz?dB/kHz) and you may x=(kHz?kHz).
» tabindex= »0″> cf. and additionally Profile 3 where in fact the indicate multitaper spectra out of for the Important Polish and the the fresh new variant are shown. As can be seen, all indicate spectra clearly increase far more steeply in the lower volume diversity (as much as 5,100 Hz) toward Simple Polish as compared to the the brand new variation.
