Voice perturbation measures, formerly defined in a somewhat ad hoc fashion, are discussed within the framework of signal theory. An attempt is made to unify a variety of existing jitter, shimmer, and noise measures on the basis of common underlying perturbation functions and their derivatives. Some simple modulations (sinusoid, Gaussian noise, linear trend) are imposed on cyclic parameters in phonation (e.g., amplitude and fundamental frequency) to test the ability of perturbation measures to detect or reject these types of modulations. It is expected that this systematic approach to perturbation analysis will be helpful in identifying the sources of irregularity in the voice and, thereby, in the detection of laryngeal disorders.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 October 2016.
All research outputs
#24,757,289
of 34,364,397 outputs
Outputs from Journal of the Acoustical Society of America
#11,338
of 14,051 outputs
Outputs of similar age
#21,188
of 22,572 outputs
Outputs of similar age from Journal of the Acoustical Society of America
#32
of 33 outputs
Altmetric has tracked 34,364,397 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 14,051 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one is in the 14th percentile – i.e., 14% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 22,572 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one is in the 3rd percentile – i.e., 3% of its contemporaries scored the same or lower than it.
