AB  - For acoustical long-term measurements based on ecological momentary assessment (EMA), we needed a solution for sending A2DP audio data to an Android smartphone. Due to Android’s software limitations, the common smartphones cannot act as the necessary sink for stereo audio. Our innovation is a wearable Bluetooth device containing a wireless transmission unit with two microphones connected to a Nexus 5 smartphone. The Nexus 5 platform was chosen, since Google performed tests featuring an Android-powered car audio system, which enables a stereo Bluetooth sink. The proposed open hardware and software solution can be used for several audio application areas, where non-intrusive long-term observations are necessary, e.g., noise exposure dosimeters.
