This paper presents the field trial results of digital audio broadcasting (DAB), DAB+ and terrestrial-digital multimedia broadcasting (T-DMB) audio systems to provide useful information about each digital radio broadcasting standard. Although the all methods are representative digital radio broadcasting standards based on Eureka-147, they have different parts from each other. This field trial results describe a reception performance of each method in various practical reception environments. To evaluate reception performance, various measurement routes are considered. These test results are able to give basic information for the choice of digital radio standard in many countries.
