Influence of Compression Thresholds and Maximum Power Output on Speech Understanding with Bone-Anchored Hearing Systems

Table 1

Mean improvement of speech reception thresholds in noise, when keeping one fitting parameters constant and changing the other one.

Fixed parameter	Changed parameter	Group A (average BC threshold 0-25 dB)	Group B (average BC threshold 25-50 dB)
	MPO low ➔ high	+0.5 dB () ^ns	+1.1 dB ()
	MPO low ➔ high	+0.0 dB () ^ns	+0.8 dB ()
	CT 65 dB ➔ 50 dB	+0.7 dB () ^ns	+0.4 dB () ^ns
	CT 65 dB ➔ 50 dB	+0.3 dB () ^ns	+0.1 dB () ^ns

ns: not significant.
