Purpose: Distortion product otoacoustic emission (DPOAE) amplitude is sensitive to the primary tone level separation effective within the cochlea. Despite potential for middle ear sound transmission characteristics to affect this separation, no primary tone level optimization formula accounts for its influence. This study was conducted to determine if inclusion of ear- and frequency-specific immittance features improves primary tone level optimization formula performance beyond that achieved using a univariate, L2-based formula...

Purpose: Healthy young controls exhibit a learning effect after undergoing repeated administrations of the sensory organization test (SOT). The primary objective of the present experiment was to determine if an SOT learning effect is present in individuals with a unilateral vestibular impairment (UVI), and if so, whether it is different from healthy controls. The secondary objective was to determine if the learning effect is dependent on the time frame of repeated SOT assessments. Method: Eleven individuals diagnosed with a UVI and 11 controls underwent 6 repetitions of the SOT over 2 visits (3 per visit all within 1 week)...

Purpose: Hearing aid management describes the skills and knowledge required for the handling, use, care, and maintenance of the hearing aid. The importance of hearing aid management skills and knowledge is evidenced by their association with hearing aid outcomes. However, the nature of this association and the influence of participant factors on this association are unknown. Accordingly, the aims of the current study were to (a) investigate participant factors that influence hearing aid management skills and knowledge and (b) investigate the impact of hearing aid management skills and knowledge on hearing aid outcomes...

Purpose: Although hearing health care clinicians provide training on hearing aid handling and management as part of the rehabilitation program, clinical studies suggest that the level of management skill demonstrated by hearing aid owners is low. In the absence of a comprehensive clinical survey to identify these shortfalls in clinical training, the objective of this study was to develop and report the psychometric properties of the Hearing Aid Skills and Knowledge Inventory (HASKI: a self-administered version and a clinician-administered version)...

Purpose: The author of this letter to the editor expresses concern about the use of the word "nonorganic" as a source of confusion in terminology. Specifically, this is in response to the December 2017 American Journal of Audiology article, "Estimating Nonorganic Hearing Thresholds Using Binaural Auditory Stimuli" (Norrix, Rubiano, & Mueller, 2017). "Nonorganic" is a source of confusion in terminology, because it can be used in two different ways. One way can mean to say there is no hearing loss...

Purpose: The purpose of this letter is to respond to Dr. Peck's (2018) letter to the editor regarding the use of the term "nonorganic" to describe hearing loss, demonstrated by the pure tone audiogram that cannot be explained or is greater than what can be explained by a physiological auditory disorder. Conclusions: We prefer the term "nonorganic" rather than the term "false and exaggerated hearing loss." "Nonorganic," in our view, is a nonjudgmental term and, as stated by Austen and Lynch (2004), implies "as little as possible about its cause" (p...

Purpose: The aim of this study was to develop a substantive theory that explains parenting stress among mothers of deaf or hard-of-hearing (D/HH) children. Method: Fifteen hearing mothers of children with severe-to-profound sensorineural hearing loss were interviewed. Interviews were transcribed verbatim, and a grounded theory approach was used to inductively analyze parental stress in mothers of D/HH children. Theory generation was achieved through triangulation of data sources and systematic organization of data into codes...

Purpose: The use of acoustic stimuli to reduce the prominence of tinnitus has been used for decades. Counseling and tinnitus sound therapy options are not currently widespread for cochlear implant (CI) users. The goal of this study was to determine whether tinnitus therapy sounds created for individuals with acoustic hearing may also benefit CI users. Method: Sixteen sounds from the ReSound Relief app (Version 3.0) were selected for the study. Sixteen participants were asked to rate the overall acceptability of each sound and to write the description of the sound they perceived...

Purpose: Compared to photon-based radiotherapy, protons deliver less radiation to healthy tissue resulting in the potential reduction of late complications such as sensorineural hearing loss (SNHL). We report early auditory outcomes in children treated with proton radiotherapy (PRT) for craniopharyngioma. Method: Conventional frequency (CF = 0.25-8.0 kHz) audiometry, extended high-frequency (EHF = 9.0-16.0 kHz) audiometry, distortion product otoacoustic emission (DPOAE) testing, and speech-in-noise (SIN) assessments were prospectively and longitudinally conducted on 74 children with a median of 2 post-PRT evaluations (range, 1-5) per patient...
