Introduction
We want to study if new replacement hearing aids (HA) compared to existing HAs improve speech intelligibility with constant task engagement by examining the pupillary response in relation to signal to noise ratio (SNR) during a Danish Hearing In Noise Test (HINT).
Materials and Methods:
21 bilateral HA users referred for CI, aged 23-82 (mean=62) were tested with existing HAs and one month post fitting with new HAs (Phonak Link M or GN (ReSound LiNXQuattro, ENZOQ) according to NAL-NL2 prescription and verified with Real Ear Measurement (REM).
The test consisted of two sessions: first a SNR was determined of 70% correct word recognition score at 65 dB SPL in HINT, thus finding the constant task engagement. This individual determined SNR was then used in another HINT while recording the pupil reaction.
Results
In this preliminary study, 18 out of 21 patients showed a change in SNR ranged from -9 dB to +7 dB with a mean difference of - 0.66 dB (SD = +4.3 dB) when comparing existing HAs with new HAs. 2 out of 21 patients showed a clear improvement in SNR with a mean difference of +18 dB (SD = +4.2 dB)
When comparing existing HAs with new replacement HAs we found a non-significant improvement of -1.8 dB (95% CI -6.93– 3.41 p=0.28) and no difference in peak pupil dilation.
Conclusions:
SNR during HINT with constant task engagement was not improved significantly when comparing new replacement HAs with existing HAs, however we found a trend of improvement.
