What is it about?
Purpose The purpose of this study was to evaluate how changing the settings of a digital receiver feature (EasyGain) affected the electroacoustic output as a function of hearing loss and receiver type. Method To assess the effects of the EasyGain setting on a Roger receiver, a Phonak Naida V90 superpower hearing aid (HA), two universal Roger X (02), two Roger 18 integrated receivers, and a Roger Inspiro transmitter were used. An electroacoustic evaluation was performed for five degrees of hearing loss ranging from a flat 40 to 80 dB HL, and for nine EasyGain settings from +8 to -8 dB with each Roger receiver. Result A three-way ANOVA indicated significant main effects of hearing loss, receiver type and EasyGain settings, as well as their two-way interactions (p < .05). Overall, the output of the integrated receiver was 2.77 dB higher than that of the universal receiver. The change in output with 2-dB changes in EasyGain setting varied with the degree of hearing loss. Conclusion To conclude, the benefits of EasyGain technology on the RMS output are dependent on the interaction of the receiver type, degree of hearing loss and EasyGain settings. The results highlight the importance of electroacoustic verification to determine appropriate settings for optimal audibility when using a remote microphone system.

Why is it important?
Our findings confirm that EasyGain setting could improve the audibility of important speech cues from the transmitter, and suggest clinical practitioners need to choose receivers carefully based on the listener’s degree of hearing loss. Our results also highlight the need for electroacoustic evaluation of remote microphone systems when used with varying levels of hearing loss.
Perspectives
It's truly fulfilling to engage in meaningful work that has a direct impact on clinical reference and can offer valuable assistance to those in need. This is the very reason why I am passionate about conducting research and pursuing a career in this field. My ultimate aspiration is for this article to successfully achieve its goal of helping others, and I am committed to putting in extra effort to ensure that this objective is consistently met.
