Metric Options: Counts1 Year3 YearSelecting 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
Sensorineurally hearing-impaired (HI) subjects often report difficulties in complex acoustical environments. To investigate whether these problems arise from specific deficits in the frequency selectivity in binaural listening conditions, thresholds were measured for a 500-Hz sinusoid in phase (So) or antiphase (Sπ) masked by a diotic notched noise (No). The equivalent rectangular bandwidth (ERB) for filters derived from diotic (NoSo) and dichotic (NoSπ) threshold curves is larger for the HI subjects than for the normal-hearing (NH) subjects. However, the ratio of binaural to monaural ERB is the same. The data indicate that there is no additional retrocochlear impairment reducing the binaural frequency selectivity of HI subjects. A specific binaural impairment was also tested by measuring the perception of binaural pitch (Huggins' pitch). Two out of eight HI subjects failed to perceive this pitch, although in the masking experiment they obtained a binaural masking-level difference of up to 10 dB. The current data therefore provide no clear evidence for a specific binaural impairment factor in hearing impairment that deteriorates several aspects of binaural processing in a similar way. © 2010 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.
