A non-transitory computer readable medium including an operating system that comprises an audio control module, the non-transitory computer readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the processors to perform operations comprising:

• receiving, by the audio control module, an audio prompt from a navigation application, the audio prompt to be presented by the mobile device, wherein the audio prompt has a first inherent loudness level;
• determining, by the audio control module, that an audio application is presenting, at a first time prior to presentation of the audio prompt, a media item at a first volume level, wherein the media item has a second inherent loudness level;
• based on the first inherent loudness level and the second inherent loudness level, defining an audible contrast amount between the media item and the audio prompt;
• based on the defined audible contrast amount, determining a second volume level that is lower than the first volume level at which to present the media item and a third volume level at which to present the audio prompt that is lower than the first volume level and higher than the second volume level;
• and
• concurrently presenting at a second time that is later than the first time, by the audio control module, the media item of the audio application at the second volume level while presenting the audio prompt at the third volume level.
