Ordinal variable considered as quantitative ?

Dear all,

I am new in the forum and my question is about ordinal variable.
The details of the experiment are :
- A xylophone maker was asked to classify 60 sounds (60 xylophone bars made
with different species of wood). So the sounds were ranked from 1 (the best
quality) to 60 (the worst).
- The wooden bars were then characterized by acoustic parameters (duration,
brightness, temporal damping, spectral center of gravity...) and by material
parameters (young's modulus, density...). All these parameters are
quantitative variables.

The main objectives of the study are:
- Which parameter(s) explain the classification?
- does exist a combination of parameters which can estimate the
classification?

To reach the objectives, can I use the multivariate regression analysis (PCR
and MLR) considering the ordinal variable Classification as quantitative? Do
exist other multivariate analysis methods to be used with an ordinal
variable?

Many thanks,

Loïc
