Two innovative audio technologies introduced at the Consumer Electronics Show (CES) offer hearing improvements, IEEE Spectrum Tech Talk reports.

AfterShokz’s headphones rest quite comfortably on the cheekbones, and use a magnetic transducer to send vibrations to the bones in the ears, creating sound, eliminating the need to put a device on or in the ear.

Silentium‘s Quiet Bubble Technology uses active noise cancellation built into an airline seat. The company’s algorithms don’t require the microphone detecting the noise to be at the same point at which the noise is going into the ear, allowing for a more compact headset design. Future uses include car seats and beds (to block out snoring).
