step 3. Performance
The new presentation regarding individual variables comes after the order given during the (4). Note that the brand new boxes shown in all rates correspond to the fresh new range between the 25th and 75th percentile; the brand new black colored dot means this new median and also the whiskers correspond to ±step one.5 inter-quartile variety; study a lot more than otherwise below which diversity was outliers consequently they are portrayed as the things regarding graph. Not many instances of significant outliers was indeed eliminated.
Profile cuatro suggests the results of your spectral peak volume from the newest burst included in Fundamental Gloss (SP) and you can new variant (NV) off /?/ along with the newest spectral include 20 to help you eleven,000 Hz.
The outcomes demonstrate that new spectral level regularity is significantly higher regarding the the fresh version compared to Practical Polish for both /?/ and you will (/?/: NV 5,490 Hz compared to. SP cuatro,176 Hz, t=8.024, p : NV 5,546 Hz vs. SP cuatro,164 Hz, t=six.706, p
Package plots to have volume out-of spectral highs out-of /?/ and also as obvious in the Simple Polish and in the latest version.
Box plots of land to possess center of the law of gravity (top) and standard deviation (bottom) regarding /?/ and as obvious within the Fundamental Polish plus in the variant
Container plots of land getting skewness (top) and you may kurtosis (bottom) out of /?/ and also as noticable into the Standard Polish as well as in the new version.
The middle of gravity beliefs regarding /?/ and you will had been somewhat large in the the fresh variation compared to Fundamental Shine (/?/: NV 5,367 Hz vs. SP cuatro,375 Hz, t=5.327, p : NV 5,205 Hz versus. SP 4,468 Hz, t=3.894, p presented notably straight down skewness thinking than just their Important Shine associated markets (/?/: NV ?0.079 compared to. SP 0.338, t=?2.050, p=.06 (from the level of analytical desire) : NV ?0.317 versus. SP 0.179, t=?dos.822, p is correct-skewed compared with the brand new spectra of one’s new variations which is skewed to the left. Kurtosis was not somewhat different inside the SP while the NV.
Package plots of land towards the spectral mountain strategies m1 (top) and m2 (bottom) from /?/ so when produced in Basic Shine plus in the latest version.
Profile seven suggests the results for the several spectral hills m1 and m2 for /?/ as well as in Practical Polish plus in the fresh variant.
The 2 measures m1 and m2 of your regression lines off frication spectra are very helpful in identifying the product quality Polish and the versions from /?/ and you will . The first regression range mountain (m1) regarding is notably reduced in new variant than in Important Gloss ( : NV 1.31 dB/kHz2 vs. SP 2.51 dB/ kHz2, t=?2.348, p
Simple Gloss variant (/?/: NV ?4.76 dB/kHz2 against. SP ?cuatro.4 dB/kHz2, t=?step 3.738, p : NV ?cuatro.91 dB/kHz2 compared to. SP ?4.six dB/kHz2, t=?4.623, p the newest spectral hill is actually significantly down on the the brand new version compared to Basic Polish on the volume may include five-hundred Hz to help you 5,100 Hz (m1). For the highest frequency range from 5,100 Hz so you can eleven,100 Hz, both /?/ and have a somewhat steeper spectral fall off toward the fresh new variant as compared to Simple Polish, Into go up/fall of your own regression line, increased kissbrides.com press the site (positive) value to have m1 setting a beneficial steeper increase of your regression range, whereas having m2, a lower life expectancy (negative) worth represents good steeper fall of your own regression range, in both mention of its particular regularity ranges regarding the Strength (Spectral Density) spectra. These devices dB/kHz2 is a result of the latest calculation of one’s slope of the regression line: m= (y2?y1)/(x2?x1) which have y=(dB/kHz?dB/kHz) and you may x=(kHz?kHz).
” tabindex=”0″> cf. including Profile step three in which the imply multitaper spectra regarding when you look at the Practical Shine additionally the the newest variant receive. As can be seen, most of the mean spectra obviously rise alot more steeply regarding the lower volume assortment (to 5,one hundred thousand Hz) toward Basic Shine when compared to the the fresh variation.
