“…However, according to Ruscetta et al (2005), a test is not useful in research or for documenting a clinical intervention unless reliability is quantified, and issues of reliability are important considerations, both in choosing test material and in interpreting test results (Cacace & McFarland, 1998). Reliability refers to the extent to which test results are repeatable at different points in time.…”

The objective of the study was to collect data on the Listening in Spatialized Noise - Sentences Test (LISN-S(R); Cameron & Dillon, 2006) from a group of children with normal hearing, over two test sessions, to determine test-retest reliability. The LISN-S produces a three-dimensional auditory environment under headphones, and is presented using a personal computer. Speech reception threshold (SRT) is determined for target sentences presented in competing speech that is manipulated in respect to location (0 degrees versus+/-90 degrees azimuth) and/or the vocal identity of the speaker/s of the stories (same as, or different to, the speaker of the target sentences). Forty-six children aged five to eleven years took part in the study. Mean changes in performance on retest on the LISN-S conditions and advantage measures ranged from 0.1 dB to 1.1 dB. Reliability (r) ranged from 0.3 to 0.8. All correlations were significant (p < 0.05). Across the range of performance measures, critical differences for test score improvements ranged from 2.5 dB to 4.4 dB, making this test suitable for detecting improvements in performance in an individual child diagnosed with central auditory processing disorder following a period of auditory compensation (such as an FM system), or training.

“…A high correlation implies that participants will, for the most part, keep their same places on test and retest. An r value of ]/0.7 is a respectable correlation to determine test-retest reliability (Howell, 1997;Ruscetta et al, 2005).…”

“…A test or clinical procedure is considered reliable if it produces the same results across repeated testing of the same subject under identical conditions (Hopkins, 2000). If good test-retest reproducibility is established, a signifi cant change in the measurements when compared to the baseline indicates functional changes rather than measurement errors or artifacts (Ruscetta et al, 2005). In spite of the increasing popularity of HFT in clinical applications, studies on the test-retest reproducibility of the HFT are scarce.…”

This study aimed to evaluate the test-retest reproducibility of the high frequency tympanometry (HFT) test measured in healthy infants. A total of 273 newborn babies (106 males and 147 females) were assessed twice (Test 1 and Test 2) on the same day, followed by two more assessments (Test 3 and Test 4) for 118 babies (48 males and 70 females) who returned six weeks later. Five HFT measures including the peak compensated static admittance and component compensated static admittance were assessed for test-retest reproducibility. The results showed no significant differences in mean values of the HFT results between the test and retest conditions for newborn (Test 1/ Test 2) and six-week-old babies (Test 3/ Test 4). High reproducibility for all HFT measures was found for both age groups, as judged by the high intra-correlation coefficients of between 0.75 and 0.95. Normal variations of the HFT measures were established using the 90% range of absolute test-retest difference. Changes in test-retest findings exceeding the 95th percentile values may be considered significant, indicating possible functional changes.

“…31,32 Ruscetta et al 32 assessed validity and reliability by performing t tests to compare 20 hearingimpaired and 20 normal-hearing participants with statistically significant results in the direction expected. Additionally, Ruscetta et al 32 reported an internal consistency reliability coefficient for these items of .800 and a test-retest reliability of .700. The psychometric integrity of scores from this instrument was also assessed by Noble et al 31 with 104 hearing impaired, sighted participants.…”

Considerable research indicates that spatial hearing in people who are blind is similar to or better than that of people who are sighted. Of particular relevance to everyday function is an individual's self-assessment of sound localization skills. In the present study, questionnaire responses by people with self-reported blindness and normal hearing indicated high self-ratings of spatial hearing skills among those who responded to the survey. Ratings for several spatial hearing situations were compared with ratings obtained from a different study of sighted individuals. Spatial hearing is used by people who are blind to avoid obstacles in the environment and to travel independently. Numerous studies indicate that horizontal sound localization performance in blind individuals is comparable to or better than that of sighted individuals (e.g., references 1-8), particularly with respect to sounds in the periphery. 9,10 In the vertical plane, localization performance of blind individuals is less accurate, probably because unique, pinna-related spectral cues are utilized, 11−14 and individual, vision-based calibration of these cues appears to be necessary. 6,15 Evidence suggests that peripheral auditory sensitivity in blind individuals (e.g., pure tone sensitivity) is similar to that of sighted individuals. 16,17 Spatial hearing differences that are reported to exist between blind and sighted individuals thus may reflect differences in the central processing of auditory input.Many auditory cues can be used in spatial hearing, depending on the acoustical environment involved and the behavior required (e.g., detection, identification, determination of direction, distance estimation). One component of spatial hearing ability has been called echolocation. In echolocation, sound localization cues are reflections of sounds produced by an emitter. For example, sounds emitted by footfalls, cane taps, or clicks, chirps, or other sounds that are either produced orally or by a mechanical generator strike objects in the environment and produce reflected sounds that can be detected and used for spatial hearing purposes. Research indicates that characteristics of an object such as size, shape, and texture can be determined in this way. 18,19 In addition to the high-frequency sounds such as hisses and clicks used in echolocation, lower-frequency cues associated with variations in the normal background sound can also provide important information for spatial hearing. 20,21 These cues are derived from naturally occurring reflected sounds. 20 Sounds reflected from stable objects, such as walls, provide information that can
