The SDS was measured at 40 dB sensation levels (SL) (65 dB hearing levels (HL), Arabic monosyllabic words).The plot shows the individual data points where each letter represents a study participant and the median (long line) with the interquartile range (25th and 75th percentile, whiskers).

An audiometric notch is present when one or more of the thresholds at 3-4, or 6 kHz exceeds the pure-tone average of the 0.5 andl kHz thresholds by 15 dB hearing level (HL) or more, and the 8 kHz threshold is at least 5 dB HL lower (better) than the highest threshold in the 3-6 kHz range.
For those cases that lacked coding of the base city at the hearing level, we relied instead on base city associated with the case in the EOIR master record.
