“…The relatively steeper off-frequency TMCs in the low threshold group are consistent with a fully functional MOC reflex. In contrast, this reflex may be partially dysfunctional in listeners with hearing impairment due to OHC damage (Collet et al 1992) and result in a relatively shallower off-frequency TMC. Previous studies have simulated the MOC reflex using the Zilany et al (Smalt et al 2014).…”

Temporal masking curves (TMCs) are often used to estimate cochlear compression in individuals with normal and impaired hearing. These estimates may yield a wide range of individual differences, even among subjects with similar quiet thresholds. This study used an auditory model to assess potential sources of variance in TMCs from 51 listeners in Poling et al. [J Assoc Res Otolaryngol, 13:91-108 (2012)]. These sources included threshold elevation, the contribution of outer and inner hair cell dysfunction to threshold elevation, compression of the off-frequency linear reference, and detection efficiency. Simulations suggest that detection efficiency is a primary factor contributing to individual differences in TMCs measured in normal-hearing subjects, while threshold elevation and the contribution of outer and inner hair cell dysfunction are primary factors in hearing-impaired subjects. Approximating the most compressive growth rate of the cochlear response from TMCs was achieved only in subjects with the highest detection efficiency. Simulations included off-frequency nonlinearity in basilar membrane and inner hair cell processing; however, this nonlinearity did not improve predictions, suggesting that other sources, such as the decay of masking and the strength of the medial olivocochlear reflex, may mimic off-frequency nonlinearity. Findings from this study suggest that sources of individual differences can play a strong role in behavioral estimates of compression, and these sources should be considered when using forward masking to study cochlear function in individual listeners or across groups of listeners.

“…Investigators have turned their attention to the study of the effects of contralateral stimuli on various parameters of evoked otoacoustic emissions in humans and in £uiimals and have demonstrated that stimulation of the ear opposite the one receiving the evoking stimulus reduces the amplitude of the otoacoustic emission (Berlin, Hood, Cecola, Jackson, & Szabo, 1993a;Berlin et al, 1994;Berlin et al, 1993b;Collet et al, 1990;Collet et al, 1992;Harrison & Bums, 1993;Kujawa, Glattke, Fallon, & Bobbin, 1992;Puel & Rebillard, 1990;Ryan, Kemp, & Hinchcliffe, 1991;Veuillet, Collet, & Duclaux, 1991). This effect is believed to be mediated by the MOC system (Berlin et al, 1994;Collet, 1993;Collet et al, 1990;Giraud, Collet, Chery-Croze, Magnan, & Chays, 1995), and suggests that the contralateral suppression of auditory nerve responses described previously may result from activity at the cochlear level.…”

“…The suppression effect on evoked otoacoustic emissions in humans is a small but consistent decrease of 1-4 dB in overall emission amplitude in the presence of a contralateral acoustic stimulus (Berlin et al, 1993b(Berlin et al, , 1994Collet et al, 1990Collet et al, , 1992Ryan et al, 1991Ryan et al, , 1996Veuillet et al, 1991;Veuillet, Duverdy-Bertholon, & Collet, 1996). Collet is credited as the first person to describe contralateral suppression of evoked otoacoustic emissions in humans (Berlin et al, 1993b;Collet et al, 1990).…”

“…Several investigators have studied the influence of contralateral stimulation on TEOAEs (Berlin et al, 1993b;Collet, 1993;Collet et al, 1990;Collet, Veuillet, Bene, & Morgon, 1992;Hood, Berlin, Hurley, Cecoia, & Bell, 1996;Ryan, & Kemp, 1996). Investigators have determined that as the SPL of a contralateral stimulus is increased, the amplitude of TEOAEs is reduced (Collet et al, 1990;Hood et al, 1996).…”

In all other instances, however, permission must be obtained from the author. The results of the present study indicate that an increase in loudness as associated by an increase in noise bandwidth affects the contralateral suppression of TEOAEs. Only the WB noise was associated with a reduction of TEOAE amplitudes. It is believed that this effect results because the WB noise has greater effective energy representation across frequency on the basilar membrane. Although the spectrum level of the WB noise is lower than that of the NB noise at the transducer, it receives more gain from the action of the cochlear amplifier than the NB noise and thus has greater energy representation on the cochlear partition. While the effective energy level on the basilar membrane may have been essentially the same for the WB and EQ noises as a result of the action of the cochlear amplifier, the WB noise was the more effective suppressor because its energy was summed across multiple critical bands. The energy in the EQ noise was confined to a sing...

“…The efferent pathways were identified and studied by numerous authors 3,4,5,6,12,13 , and contralateral inhibitions suppression was initially studied by Collet 8 and later confirmed by many others 10,14,15 . In 1999, Pialarassi 10 studied the suppression of transient and distortion product otoacoustic emissions with contralateral stimulus by a narrow band noise in 48 individuals with normal hearing and 9 individuals with retrocochlear disease.…”

School learning can be hampered if there are defects on the central auditory process. Since those with auditory deficiency can be rehabilitated, it is fundamental that we identify them. Otoacoustic emissions test has low cost and operational ease. Study design: clinical and experimental. Aim: to study the relationship between school learning and transient otoacoustic emission suppression by contralateral stimuli. Material and Methods: 39 individuals, from 7 to 12 years of age were evaluated, 19 (48.7%) with good school performance and 20 (51.3%) poor performers. Results: A transient otoacoustic emission suppression failure for contralateral acoustic stimuli was more frequently found among children with poor school performance. We established a value of 1.6 dB SPL for emission reduction that characterized those children as belonging to the poor learning performance group: sensitivity 65%, specificity 72,2%, accuracy of 68.4%, positive predictive value of 72.2%. Conclusion: The contralateral emission suppression test of the right ear can be predictive of school difficulties in individuals from six to twelve years of age.
