Predicted Gain and Functional Gain With Transcranial Routing of Signal Completely-in-the-Canal Hearing Aids

Abstract: Transcranial routing of signal (TCROS) was accomplished using completely-in-the-canal (CIC) hearing aids in 5 profoundly unilaterally hearing-impaired individuals. The functional gain realized by the participants far exceeded the gain predicted by measuring the acoustic output and real ear aided response of the hearing aids. The difference between predicted and functional gain increased with signal frequency and was attributed at least in part to mechanical vibration of the hearing aid in the external canal.

“…22 This method is practically challenging given the requirement for a deep, close fitting of a powerful hearing aid without feedback. Protocols for both CROS aid fitting 20 and evaluation 21,23 are available. The degree of benefit of CROS may depend on the nature of difficulties experienced.…”

“…Hayes and Chen [16] also reported on the CIC device, but their study group only comprised three cases. As far as we know, little attention has been paid to this type of transcranial CROS method, since then [14, 17]. …”

“…An alternative approach to providing contralateral routing of sound than with conventional CROS and BICROS hearing aid systems is with a so‐called transcranial CROS hearing aid, most commonly referred to as t‐CROS. It is argued that the t‐CROS stimulates the contralateral cochlea via bone conduction 10, 11. This device can be regarded as somewhat experimental, as there seems to be some variability in patient outcome 12, 13.…”
