“…Since this was an exceptionally long study (27–101 days), we hypothesize that the long-term unilateral mold induced some hearing loss to the blocked ear. This is in line with other findings showing that temporary conductive hearing loss leads to a binaural hearing impairment that lasts beyond the duration of the impairment (for a review, see Moore et al, 2001). No other study implementing long-term monaural blocks obtained such an effect, but no other occluded the ear for such a long period.…”

In this article we present a review of current literature on adaptations to altered head-related auditory localization cues. Localization cues can be altered through ear blocks, ear molds, electronic hearing devices, and altered head-related transfer functions (HRTFs). Three main methods have been used to induce auditory space adaptation: sound exposure, training with feedback, and explicit training. Adaptations induced by training, rather than exposure, are consistently faster. Studies on localization with altered head-related cues have reported poor initial localization, but improved accuracy and discriminability with training. Also, studies that displaced the auditory space by altering cue values reported adaptations in perceived source position to compensate for such displacements. Auditory space adaptations can last for a few months even without further contact with the learned cues. In most studies, localization with the subject's own unaltered cues remained intact despite the adaptation to a second set of cues. Generalization is observed from trained to untrained sound source positions, but there is mixed evidence regarding cross-frequency generalization. Multiple brain areas might be involved in auditory space adaptation processes, but the auditory cortex (AC) may play a critical role. Auditory space plasticity may involve context-dependent cue reweighting.

“…Similarly, children who experience a transient hearing loss have difficulty with binaural hearing (Hall et al, 1995; Hall et al, 1998; Hogan et al, 1996; Moore et al, 1991; Pillsbury et al, 1991) and speech processing (Gravel et al, 1992; Gravel et al, 1996; Hall et al, 2003; Jerger et al, 1988) gradually improve once peripheral hearing is restored. Even adult humans with earplug induced or age related hearing loss benefit from training (Ferguson et al, 2014; Irving et al, 2011; Moore et al, 2001). Since training is unlikely to restore cochlear function, the resulting behavioral improvements are likely due to central mechanisms.…”

Developmental hearing loss impedes auditory task learning and performance in gerbils

et al. 2017

The consequences of developmental hearing loss have been reported to include both sensory and cognitive deficits. To investigate these issues in a non-human model, auditory learning and asymptotic psychometric performance were compared between normal hearing (NH) adult gerbils and those reared with conductive hearing loss (CHL). At postnatal day 10, before ear canal opening, gerbil pups underwent bilateral malleus removal to induce a permanent CHL. Both CHL and control animals were trained to approach a water spout upon presentation of a target (Go stimuli), and withhold for foils (Nogo stimuli). To assess the rate of task acquisition and asymptotic performance, animals were tested on an amplitude modulation (AM) rate discrimination task. Behavioral performance was calculated using a signal detection theory framework. Animals reared with developmental CHL displayed a slower rate of task acquisition for AM discrimination task. Slower acquisition was explained by an impaired ability to generalize to newly introduced stimuli, as compared to controls. Measurement of discrimination thresholds across consecutive testing blocks revealed that CHL animals required a greater number of testing sessions to reach asymptotic threshold values, as compared to controls. However, with sufficient training, CHL animals approached control performance. These results indicate that a sensory impediment can delay auditory learning, and increase the risk of poor performance on a temporal task.

“…In the first years of life, it is assumed that auditory and language development undergo a sensitive period [Moore, 2002;Moore et al, 2001]. As auditory input during this time has a stronger effect on developing certain skills than prior or after, even a temporally limited deprivation, as occurs during OM incidents, can affect auditory and language abilities.…”

“…As auditory input during this time has a stronger effect on developing certain skills than prior or after, even a temporally limited deprivation, as occurs during OM incidents, can affect auditory and language abilities. On investigating the consequences of auditory impairments during this time, Moore et al [1999Moore et al [ , 2001 found a decline of binaural hearing in animals that were unilaterally ear-plugged in juvenile. They also found that, after a period of hearing loss, binaural hearing improves when peripheral function is normal over a time.…”

Otitis Media and Speech-in-Noise Recognition in School-Aged Children

et al. 2008

View full text Add to dashboard Cite

The present study examined the long-term consequences of otitis media (OM) on speech perception abilities in noise. 55 children with a prospective 3-monthly documented middle-ear status and hearing loss between birth and 24 months completed a ‘speech-in-noise’ (SPiN) test at the age of 7 years. Both hearing loss and the cumulation of uni- and bilateral OM incidents in early life were significantly correlated to the performance on the SPiN test at school age. Other background factors such as socio-economic status, language perception and cognitive development did not predict the performance on the SPiN test. Only the language production score at age 7 was also significantly related to the score on the SPiN test. The present study deals with the risk of OM in early life and its accompanied hearing loss on auditory processing, specifically speech perception in noise, up to school age.
