You want to run an ACR subjective listening test?  You can start by downloading (for free) ITU-T P.800 from the www.itu.int web site.  You would also need suitable listening material .. you can either purchase this from the ITU, download for free from the Open Speech Repository (hosted on www.voiptroubleshooter.com) or record some material yourself.
