“…Reavis et al [32] proposed that a DPOAE reduction of 4 dB or greater at adjacent f 2 frequencies constituted an ototoxic change. However, both of these studies were conducted in adults, and the criterion selected for this study was more consistent with the limits exceeding normal variation in children identified by Sockalingam et al [28]. In addition, the finding that three children receiving high cumulative dosages of carboplatin were identified as having ototoxic change in DPOAE levels was in agreement with previous research in animal models.…”

“…Currently, there is no universal agreement on the criterion for ototoxic change using OAE tests. Sockalingam et al [28] calculated minimal changes in DPOAE level that exceeded the limits of test-retest reliability at individual f 2 frequencies in children aged 5–12 years. Based on their data, the average minimal change exceeding the limits of normal variation at four f 2 frequencies between 2530–7029 Hz was 6.47 dB.…”

Objective Carboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in individual children. Methods A prospective repeated measures study. Ten children with a median age of 7.6 months (range, 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were examined. Distortion-product otoacoustic emissions were acquired from both ears of the children with 65/55 dB SPL primary tones (f2= 793–7996 Hz) and a frequency resolution of 3 points/octave. Distortion-product otoacoustic emission levels in dB SPL were measured before chemotherapy treatment (baseline measurement) and after 3–4 courses of chemotherapy (interim measurement). Comparisons were made between baseline and interim distortion-product otoacoustic emission levels (collapsed across ears). Evidence of ototoxicity was based on criterion reductions (≥ 6 dB) in distortion-product otoacoustic emission levels. Results Significant differences between baseline and interim mean distortion-product otoacoustic emission levels were only observed at f2=7996 Hz. Four children exhibited criterion reductions in distortion-product otoacoustic emission levels. Conclusions Mean distortion-product otoacoustic emission levels at most frequencies were not changed following 3–4 courses of carboplatin chemotherapy in children with retinoblastoma. However, on an individual basis, children receiving higher doses of carboplatin exhibited criterion reductions in distortion-product otoacoustic emission level at several frequencies. These findings suggest that higher doses of carboplatin affect outer hair cell function, and distortion-product otoacoustic emission tests can provide useful information when monitoring children at risk of developing carboplatin ototoxicity.

“…Generally, high test-retest reliability is reported for TEOAEs (Harris et al, 1991;Vedantam & Musiek, 1991;Franklin et al, 1992;Engdahl et al, 1994;Marshall & Heller, 1996;Dieler et al, 1999) as well as for DPOAEs (Franklin et al, 1992;Roede et al, 1993;Zhao & Stephens, 1999;Shehata-Dieler et al, 1999;Beattie & Bleech, 2000;Beattie et al, 2003;Hallenbeck & Dancer, 2003;Ng & McPherson, 2005;Mills et al, 2007;Sockalingam et al, 2007;Wagner et al, 2008). Test-retest measurements without probe-replacement has the smallest amount of variability which is indicative for the intrinsic variability of emission amplitudes, while a larger variability is determined after probe-refi tting.…”

“…There are several factors contributing to the variability of EOAE amplitude. First, the reliability is affected by the recording instrument, calibration, test parameters, and environmental factors (Zhao & Stephens, 1999;Hallenbeck & Dancer, 2003;Mills et al, 2007;Sockalingam et al, 2007), as well as subject-generated noise during breathing, swallowing, muscle and joint movement, or vascular pulsation (Vedantam & Musiek, 1991;Zhao & Stephens, 1999;Hallenbeck & Dancer, 2003;Sockalingam et al, 2007). External, environmental noise can be caused by the probe-tip placement, i.e.…”

Knowledge regarding the variability of transient-evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) is essential in clinical settings and improves their utility in monitoring hearing status over time. In the current study, TEOAEs and DPOAEs were measured with commercially available OAE-equipment in 56 normally-hearing ears during three sessions. Reliability was analysed for the retest measurement without probe-refitting, the immediate retest measurement with probe-refitting, and retest measurements after one hour and one week. The highest reliability was obtained in the retest measurement without probe-refitting, and decreased with increasing time-interval between measurements. For TEOAEs, the lowest reliability was seen at half-octave frequency bands 1.0 and 1.4 kHz; whereas for DPOAEs half-octave frequency band 8.0 kHz had also poor reliability. Higher primary tone level combination for DPOAEs yielded to a better reliability of DPOAE amplitudes. External environmental noise seemed to be the dominating noise source in normal-hearing subjects, decreasing the reliability of emission amplitudes especially in the low-frequency region.

“…Test/retest reliability of DPOAEs has been examined thoroughly in humans to assess the clinical usefulness of this measure (for recent studies, see Sockalingam et al ., 2007; Wagner et al ., 2008; Stuart et al ., 2009; Keppler et al ., 2010). However, reliability of DPOAEs has been examined less thoroughly in animals, and in only a few animal models (Harding et al ., 2002; Rasmussen et al ., 2005; Parrazini et al ., 2006; Park et al ., 1995).…”

This study examines the test-retest reliability of distortion-product otoacoustic emissions (DPOAEs) in ketamine-anesthetized common marmosets (Callithrix jacchus). DPOAE gain functions were measured at 16 f2-frequencies between 3 – 24 kHz. Test-retest reliability was assessed at the following time intervals: 1) Interleaved, in which two gain functions were obtained at each frequency before advancing to the next frequency, 2) Immediate, wherein one gain function was collected at all f2-frequencies and the retest was immediately performed without removing the probe tip, 3) Short-term, in which the retest followed a 10-min period with the probe removed, and 4) Long-term, wherein the retest was performed at least one week after the initial test. Reliability was assessed using four correlation coefficients used in the literature. Test-retest reliability was best in the interleaved interval and worst in the short-term interval. In general, reliability was best when primary-tone levels were high. Correlation coefficients decreased at frequencies above 12-kHz in the short-term and long-term intervals, but the decrease was more substantial in females than in males in the long-term interval. At frequencies below 12 kHz, same-day measurements (2, 3) were less repeatable, regardless of whether the probe was removed, which may be due to time under anesthesia. These results have implications for DPOAE studies where repeated measures are required and when treatment or group differences are small.
