The last few decades have seen amazing improvements in cochlear implant technology. Professor Michael Dorman reveals what they really sound like, and how they can help out with more than just our hearing. But should we be advocating cochlear implants at all? We chat with deaf graphic designer Brandon Edquist about why he chooses not to use his implant, and why the Deaf community is up in arms against them.  Twenty Thousand Hertz is produced out of the studios of Defacto Sound, and hosted by Dallas Taylor. Follow the show on Twitter & Facebook.  Become a monthly contributor at 20k.org/donate. If you know what this week's mystery sound is, tell us at mystery.20k.org. Episode transcript, music, and credits can be found here: https://www.20k.org/episodes/deafgain Learn more about your ad choices.
