The ERB-rate scale, or ERB-number scale, can be defined as a function ERBS(f) which returns the number of equivalent rectangular bandwidths below the given frequency f. The units of the ERB-number scale are known ERBs, or as Cams, following a suggestion by Hartmann. [ 3 ]
Some non-mel auditory-frequency-scale formulas use the same form but with much lower break frequency, not necessarily mapping to 1000 at 1000 Hz; for example the ERB-rate scale of Glasberg and Moore (1990) uses a break point of 228.8 Hz, [15] and the cochlear frequency–place map of Greenwood (1990) uses 165.3 Hz.

Type 3 diabetes is a proposed pathological linkage between Alzheimer's disease and certain features of type 1 and type 2 diabetes. [1] Specifically, the term refers to a set of common biochemical and metabolic features seen in the brain in Alzheimer's disease, and in other tissues in diabetes; [1] [2] it may thus be considered a "brain-specific type of diabetes."
The pioneering work of Ladefoged [16] used the Mel scale because this scale was claimed to correspond more closely to the auditory scale of pitch than to the acoustic measure of fundamental frequency expressed in Hertz. Two alternatives to the Mel scale are the Bark scale and the ERB-rate scale. [17]

[6] [7] The ERB can be converted into a scale that relates to frequency and shows the position of the auditory filter along the basilar membrane. For example, ERB = 3.36 Hz corresponds to a frequency at the apical end of the basilar membrane, whereas ERB = 38.9 Hz corresponds to the base, and a value of 19.5 Hz falls half-way between the two.

On top of that, the oil producer plans to ramp its annual share repurchase rate from $5 billion to $7 billion, with the aim of buying back over $20 billion in stock in the first three years ...
The risk is 5–6% (similar to that of a woman in her early 40s giving birth), [394] [395] compared with a baseline risk of 3–4%. [395] The effects of inbreeding depression , while still relatively small compared to other factors (and thus difficult to control for in a scientific experiment), become more noticeable if isolated and maintained ...
