F0: Standard
measurement, except data weighted towards
|
|
loud
regions of high uniformity (e.g. vowel
centers).
|
|
|
Loudness: Not the
same as RMS amplitude.
|
|
|
Uses
Steven’s Mark VII (1971) algorithm to emulate
perceptual
|
|
judgments. (Mark VII is an
improved version of the ISO-R532 Method
|
|
A standard
noise measurement.)
|
|
|
Differences from RMS:
|
|
|
| • |
Close to
human perception.
|
|
|
| • |
Takes
information from a broad range of frequencies, rather
than
|
|
primarily
from the lowest harmonic.
|
|
|
| • |
More
stable; not strongly affected by accidental alignments of
f0 and F1.
|
|
| • |
Algorithm
loosely analogous to early stages of human auditory
system.
