Popis:	Objectives To define fitting ranges for nine bone conduction devices (BCDs) over different frequencies based on the device's maximum power output (MPO) and to validate the assessment of MPO of bone conduction devices in the ear canal. Background MPO is an important characteristic when fitting bone conduction devices. It is the highest output level a device can deliver and is one of the major determinants of a device's fitting range. A skull simulator can be used to verify MPO of percutaneous bone conduction devices. No such simulator is available for active and passive transcutaneous devices. Design The MPO of nine different BCDs was assessed either by real-ear measurements and/or with skull simulator measurements. Main outcome measures MPO and cross-validation of the methods using the Bland-Altman method. Results Percutaneous bone conduction devices have higher MPO levels compared to active and passive transcutaneous devices. This results in a wide dynamic range of hearing for percutaneous devices. Moreover, the assessment of MPO by real-ear measurements was validated. Conclusion Based on MPO data, fitting ranges were defined for nine bone conduction devices over seven frequencies.
