Not that I know of.

For the grammar I would suggest

noise_table ( input [ , name_or_null [, interp ] ] )

There is some similarity between this idea and $table_model and its
control strings. noise_table could use a similar approach with a control
string (and $table_model could be extended to have logarithmic
interpolation at the same time).
