Effect of masker orientation on masking efficacy in soundscape applications

Adding desired sounds, also known as auditory masking, to the sonic environment is one of the practiced soundscape implementation strategies. At present, soundscape researchers are evaluating the perceived improvement in pleasantness of the soundscape in the presence of pleasing sounds through liste...
