How to turn your Apple laptop with built-in microphone and GarageBand into a functioning hearing aid:

  1. Open Garageband and create a new song.
  2. Delete the piano track that comes up automatically.
  3. Plug in a pair of headphones.
  4. Create a new track. Make it a vocal track. Make sure you choose "monitor on."
Your laptop's built-in microphone will now act as a hearing aid/sound enhancer. All sounds in the room will be amplified for your listening pleasure. I used this trick over the weekend when my clogged sinuses caused dramatic hearing loss at an important out-of-town event. It worked very well. If your headphones leak enough sound, you may hear feedback. Just adjust the input or output volume in GarageBand until the feedback goes away.
