Convention Paper

AES Convention 114 · Paper 5738 · March 2003

Abstract

The question of the validity of listening tests in laboratory is considered in the case of the speech quality transmitted by mobile phone. First of all, tests are run outside, in two places characterized by two different environments. Degradations are introduced in the transmitted speech signal heard by subjects, and sound environments as well as transmitted speech signals are recorded. In a second time, tests are carried out in laboratory by reproducing recorded speech signals through handsets and recorded sound environments with a Dolby Surround system. Results show a weak impact of the sound environment on quality judgments and validate the use of listening tests in laboratory.
