Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose: The Microphone and Receiver in the ear (M&RIE) hearing aid is designed to consider the pinna cues by placing an additional microphone along with a standard receiver at the entrance of the ear canal. There is a need to clinically validate the technology using speech identification measures, as a literature shortage exists. The objective of the study was to evaluate speech identification and quality rating with hearing aids fitted with standard and M&RIE receivers. Method: Twenty individuals (mean ± SD age being 34.10 ± 11.9 years) with mild-to-moderately severe sensorineural hearing loss were divided into two groups: naïve and experienced. Their speech identification obtained using the receiver in the ear hearing aid compatible with standard and M&RIE receivers were compared. The study assessed speech identification in quiet using ten sentences, calculated SNR-50 using the Spearman–Karber equation, and used an 11-point scale for self-perceived quality rating. Results: The study analyzed data using SPSS and found no significant difference between naive and experienced hearing aid users in quiet and SNR-50 conditions (p > 0.05). However, naive users rated higher in clarity, naturalness, pleasantness, and overall impression of standard receiver settings. Across different receiver settings, both naïve and experienced groups revealed better speech identification with the M&RIE receiver for both SIS (p < 0.05) and SNR-50 (p < 0.05) measures. Conclusion: The study found that placing a third microphone in the ear canal improves speech identification and quality rating in both naïve and experienced users, with pinna and ear canal resonance playing a crucial role in prescribing hearing aid gain.
