Abstract :
Transmission delays are unwanted effects of every day telecommunication systems. These effects influence the overall quality of a telephony connection as perceived by end users. This article summarizes known subjective experiments testing the influence of delays on the perceived quality. In order to find a possible explanation for the differences in the results of those experiments a new conversational test was conducted. The new subjective tests are also presented and compared to already existing experiment results.
