The noiseModels function returns the New High Noise Model and New Low Noise Model
from the Peterson paper referenced below. Values are returned for the specific frequencies specified in
the freq argument.
noiseModels(freq)A list is returned with elements nhnm and nlnm containing the high and
low noise models, respectively.
a vector of frequencies at which to generate noise model values
