The disclosed technology generally relates to a microphone device configured to receive sound from different beams, where each beam has a different spatial orientation and is configured to receive sound from different directions. The microphone device is also configured to process the received sound using a generic or specific head related transfer function (HRTF) to generate processed audio and transmit the processed audio to hearing devices worn by a hearing-impaired user. Additionally, the microphone device can use a reference line and/or reference point when processing the received audio.
