The overall influence of test object modifications on the signal quality can be observed immediately after 6 min. simulation time in this example. This test corresponds to 5.46 hours ongoing subjective listening tests with evaluation of only one parameter dependency! The overall influence of test object modifications on the signal quality can be observed immediately after 6 min. simulation time in this example. This test corresponds to 5.46 hours ongoing subjective listening tests with evaluation of only one parameter dependency!
