This paper presents work on finding acoustic parameters suitable to convey a sense of difference in geographic distance through the concepts of “near”, “middle” and “far”. The context for use is a mobile application for navigation services. A set of acoustic parameters was selected based on how sound naturally travels through and is dispersed by the atmosphere. One parameter without direct acoustic connection to distance was also selected. Previous works corroborate the choice of parameters in the context of the project. Results show that modulating multiple parameters simultaneously to express distance gives a more robust experience of difference in distance compared to modulating single parameters. The ecological parameters low-pass filter and reverb gave the test’s subjects the most reliable and consistent experience of difference in distance. Modulating the parameter pitch alone was seen to be an unreliable method. Combining the pitch parameter with the reverb parameter gave more robust results.
