This Perspectives highlighted research on assessments of cochlear hair cells and middle ear function. We examined measurement techniques used to separate the transient-evoked otoacoustic emission (TEOAE) response from the stimulus, and discussed how the nonlinear differential and the double-source, double-evoked techniques affect TEOAE characteristics. The significance of measuring the short latency component of the TEOAE was discussed. We explored the effects of oxaliplatin, cisplatin, and carboplatin on objective and subjective high-frequency auditory measures in adults. We shared how distortion-product otoacoustic emission (DPOAEs) and ultra-high frequency, pure-tone audiometry can be used to obtain a more comprehensive hearing profile and treatment plan for adults receiving platinum chemotherapies. Finally, we reviewed standard single- and multi-frequency tympanometry measures and wideband acoustic immittance (WAI) measurements, including wideband energy reflectance and wideband absorbance tympanometry. Normative and pathological findings WAI findings were shared. More detailed middle-ear assessments can be used as a screening and a diagnostic tool for middle ear disorders and for newborn hearing screening. Audiologists should include otoacoustic emission testing and multifrequency and wideband tympanometry in their clinical “toolkits.”

This Perspectives focused on cognition and hearing abilities in adults. We shared how working memory capacity and attention should be considered when selecting and programming amplification and providing aural rehabilitation for individuals with hearing loss. Individuals with higher working memory capacity are able to utilize fast-acting compression settings to aid in speech understanding in complex listening environments, while those with lower working memory can experience negative repercussions from such settings. Additionally, clinicians can counsel on cognitive effects on speech understanding and involve top-down strategies in their auditory training. We also examined the effects of aging on psychoacoustic performance, noting an association between cognition and discrimination abilities in older adults. Factors like impaired temporal processing and reduced frequency selectivity impact hearing abilities of adult clients in the clinic, but are rarely assessed in a standard hearing evaluation. Finally, we examine why pure-tone threshold testing is insufficient at predicting hearing handicap in the adults with minimal to mild hearing loss, and how to assess which of these individuals would benefit from rehabilitation and/or amplification. Factors such as previous noise exposure, age, working memory, ability to use conversational context, and speed of auditory processing are important to consider.

This Perspectives focused on minimal to mild hearing loss in infants and children. We summarized how mild transient hearing loss, when induced during a developmental critical period, can cause lingering impairment in auditory perception. An animal model was used to study how hearing loss affected cellular mechanics and processing in the auditory cortex, and how these changes resulted in perceptual deficits. We shared the current opinion on implications of minimal to mild permanent hearing loss (MMHL) in children, and how to determine the optimal management approach. Use of FM systems for MMHL and fitting recommendations were discussed. Finally, we presented how to determine whether hearing amplification is appropriate for an infant with mild bilateral hearing loss and discussed recommendations for fitting the hearing aids. We discussed additional factors of concomitant handicap, mobility considerations, listening environment, and family readiness and motivation, which should be considered when determining the optimal hearing management approach for an infant with mild bilateral hearing loss.

This issue of Perspectives focused on hearing loss associated with specific medical conditions. We summarized recent research findings on HIV and hearing impairment and identified regions of the auditory system which seem to be most at-risk in cases of HIV infection. We reviewed the sensitivity, specificity, and limitations of the conventional (slow stimulus rate) click and frequency specific electrocochleography measure and describe two novel and promising techniques in electrocochleography useful in the assessment of Ménière’s disease. Finally, the authors presented a review of genetic considerations in hearing impairment, and discussed the issues and implications of genetic screening and testing for individuals with hearing impairment.

This issue of Perspectives focused on hearing difficulties in the unexpected context of a normally-functioning peripheral auditory system. We summarize central auditory processing disorders. Then, we described abnormal auditory findings in mild traumatic brain injury. Finally, we described the conditions known as obscure auditory dysfunction, hidden hearing loss, and King-Kopetzky syndrome and their possible causes, assessments, and interventions.
