How does TransEar compare to CROS or BICROS hearing aids?
A CROS is used when when an individual has a severe or profound loss in one ear, and the other side has such good hearing that it doesn’t require amplification. An ear mold containing a microphone is positioned in the dead ear in order to receive sound on that side. Sound is transferred either via a wire, or wirelessly, to a hearing instrument in the better ear. So even though it doesn’t need amplification, the good ear is still occluded. BiCROS is used when an individual has a severe or profound loss in one ear, but even the *better* ear requires amplification. (So a BiCROS affects both ears.) An ear mold containing a microphone is positioned in the dead ear in order to receive sound on that side. Sound is transferred either via a wire, or wirelessly, to a hearing instrument in the better ear in order to take advantage of that cochlea. The hearing instrument in the better ear now has two functions: it receives the sound from the deaf side, and it also amplifies the sound. So in both c
