AB  - This study investigates the impact of relaxing presentation methods on listening tests by comparing results from two identical listening experiments carried out on two countries and comprising two presentation methods: the ITU-T P.800 Absolute Category Rating (ACR) recommendation and a modified version of it where assessors had more control on the reproduction of the samples. Compared with the standard method, test duration was reduced on average 37% in the modified version. No significant effects of the method used on the ratings of codecs were found, but a significant effect of site on ratings and duration were found. We hypothesize that in the latter case, cultural differences and instructions to the assessors could explain these effects.
