Bionic ear

Bionic ear

An advanced artificial ear implant. A collection of invisible subdermal microphones capture sound and transmit it to a biogel nerve interface that links directly with the auditory nerve. It's sensitive enough to hear a cat before you see it, can't be damaged by loud noise, and automatically tunes itself to pick out meaningful sounds in noisy environments.

A Bionic ear is an ear replacement that has 125% efficiency, increasing hearing by providing 25% better part efficiency.


Bionic ears can be purchased from traders or crafted with Plasteel 10 plasteel and Advanced component 3 Advanced components on the fabrication bench after Bionic Replacements has been researched. They require a crafting skill of 8.


Since the game gives a greater weighting on the more capable part when calculating hearing, with it contributing to 75% of a pawn's hearing capability, installing a single bionic ear increases hearing by 19%, and a second increases it by 6% to the expected 125%.

A colonist with hearing loss or a cochlear implant in the non-bionic ear will still have over 100% hearing.

Hearing impacts only social skills and animal taming/training. However, all hearing-based stats have a 100% cap on the amount of hearing considered — there is no benefit to having a hearing higher than 100%. This makes bionic ears only useful when a colonist already has damaged hearing.
