Verification Of A Mobile Psychoacoustic Test System, Jordana C. Soares, Sangamanatha Veeranna, Vijay Parsa, Chris Allan, Winnie Ly, Minh Duong, Paula Folkeard, Sheila Moodie, Prudence Allen

Faculty Publications

Many hearing difficulties can be explained as a loss of audibility, a problem easily detected and treated using standard audiological procedures. Yet, hearing can be much poorer (or more impaired) than audibility predicts because of deficits in the suprathreshold mechanisms that encode the rapidly changing, spectral, temporal, and binaural aspects of the sound. The ability to evaluate these mechanisms requires well-defined stimuli and strict adherence to rigorous psychometric principles. This project reports on the comparison between a laboratory-based and a mobile system’s results for psychoacoustic assessment in adult listeners with normal hearing. A description of both systems employed is provided. …

Zika Virus Infection Causes Widespread Damage To The Inner Ear, Kathleen T. Yee, Biswas Neupane, Fengwei Bai, Douglas E. Vetter

Faculty Publications

Zika virus (ZIKV) has been recently recognized as a causative agent of newborn microcephaly, as well as other neurological consequences. A less well recognized comorbidity of prenatal ZIKV infection is hearing loss, but cases of hearing impairment following adult ZIKV infection have also been recognized. Diminished hearing following prenatal ZIKV infection in a mouse model has been reported, but no cellular consequences were observed. We examined the effects of ZIKV infection on inner ear cellular integrity and expression levels of various proteins important for cochlear function in type I interferon receptor null (Ifnar1^−/−) mice following infection at …

Speech-Language Pathologists' Collaboration With Interpreters: Results Of A Current Survey In California, Terry Saenz, Henriette W. Langdon

Faculty Publications

One of the challenges of bilingual speech and language assessment, intervention, and conferencing is the effective collaboration with interpreters in such interpreted interactions when the professional does not share the same spoken language with the client. A survey of California speech-language pathologists who were members of the California Speech-Language-Hearing Association (CSHA) was performed to obtain information on their training to collaborate with, experiences with, and opinions of interpreters. In addition, these professionals were surveyed about the training of the interpreters and suggestions for improvement in interpreted interactions. Findings from 229 participants indicated that: (a) Most of the speech-language pathologists had …

Awareness And Knowledge Of Cochlear Implants Among Speech-Language Pathologists, Kimberly Ward, Kimberly Grubbs, Amitava Biswas

Faculty Publications

Speech-Language Pathologists work closely with individuals who have received cochlear implants across a multitude of settings which include early childhood education centers, schools, hospitals and skilled nursing facilities. However, previous research suggests that Speech-Language Pathologists do not have the adequate skills or knowledge to work with clients who have received cochlear implants. To assess whether Speech-Language Pathologists in the state of Mississippi had similar results as in the previous studies, a questionnaire was used to assess knowledge on cochlear implants. The results are consistent with previous studies which suggest that there is an overall lack in cochlear implant competency, specifically …

The Role Of Efferent Reduction Of Cochlear Compression In The Detection Of Tones In Noise, Shaum Bhagat, Anusha Yellamsetty

Faculty Publications

Stimulation of medial olivocochlear (MOC) efferent neurons reduces basilar membrane (BM) sensitivity and increases the slope of BM input-output (I/O) functions in animal models. Decreased compression of I/O functions associated with activation of MOC efferent neurons may assist in extending the neural response to the tone above that of noise, leading to an improvement in masked thresholds. To evaluate this hypothesis, the distortion-product otoacoustic emission (DPOAE) I/O function, a proxy measure of BM compression, was examined in conditions with presentation of contralateral noise. DPOAE I/O functions were measured at f2 frequencies of 1000 and 2000 Hz in 16 normal-hearing adults. …

Interpreter-Assisted Speech-Language Intervention In Poland: Needs, Possibilities And Prospects (Współpraca Polskiego Logopedy Z Tłumaczem – Potrzeby, Możliwości I Perspektywy), Katarzyna Gaweł, Henriette Langdon, Katarzyna Węsierska

Faculty Publications

Due to the constantly evolving global demographic situation, speech-language therapists (SLTs, also: speech-language pathologists – SLPs) have to deal with an increasing workload of bilingual/multilingual clients. This article presents results of a survey conducted among Polish SLTs aimed at investigating their views with regards to the possibility of collaboration with an interpreter during therapeutic intervention. The original version of the questionnaire (Gaweł & Węsierska, 2014) used in this survey was filled out by 206 respondents from different areas across Poland. The following issues were addressed in the study: the SLTs’ views on the incidence of bilingualism in Poland, their self-evaluation …

Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat

Faculty Publications

Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. This hypothesis was directly tested by measuring both forward- and simultaneous-masked psychophysical tuning curves. Sharper filter tuning (i.e., higher Q10) was observed in musicians compared to nonmusicians. Findings suggest musicians' pervasive listening benefits may be facilitated, in part, by superior spectral processing/decomposition as early as the auditory periphery.

Concordance Between The Chang And The International Society Of Pediatric Oncology (Siop) Ototoxicity Grading Scales In Patients Treated With Cisplatin For Medulloblastoma, Johnnie Bass, Jie Huang, Arzu Onar-Thomas, Kay Chang, Shaum Bhagat, Murali Chintagumpala, Ute Bartels, Sridharan Gururangan, Tim Hassall, John Heath, Geoffrey Mccowage, Richard Cohn, Michael Fisher, Giles Robinson, Alberto Broniscer, Amar Gajjar, James Gurney

Faculty Publications

BackgroundReporting ototoxicity is frequently complicated by use of various ototoxicity criteria. The International Society of Pediatric Oncology (SIOP) ototoxicity grading scale was recently proposed for standardized use in reporting hearing loss outcomes across institutions. The aim of this study was to evaluate the concordance between the Chang and SIOP ototoxicity grading scales. Differences between the two scales were identified and the implications these differences may have in the clinical setting were discussed.ProceduresAudiological evaluations were reviewed for 379 patients with newly diagnosed medulloblastoma (ages 3–21 years). Each patient was enrolled on one of two St. Jude clinical protocols that included craniospinal …

Time-Frequency Analysis Of Transient-Evoked Otoacoustic Emissions In Children Exposed To Carboplatin Chemotherapy, Shaum Bhagat, Johnnie Bass, Ibrahim Qaddoumi, Rachel Brennan, Matthew Wilson, Jianrong Wu, Carlos-Rodriguez Galindo, Alessia Paglialonga, Gabriella Tognola

Faculty Publications

The aims of this study were to characterize and quantify time-frequency changes in transient-evoked otoacoustic emissions (TEOAEs) recorded in children diagnosed with retinoblastoma who were receiving carboplatin chemotherapy. A signal processing technique, the wavelet transform (WT), was used to analyze TEOAE waveforms in narrow-band frequency components. Ten children (aged 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were enrolled in the study. TEOAEs were acquired from the children with linear sequences of 70 dB peak equivalent SPL clicks. After WT analysis, TEOAE energy, latency and normalized energy in the narrow-band frequency components were compared before and during carboplatin chemotherapy treatment …

Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat

Faculty Publications

Chemotherapy is often used in the conservative management of retinoblastoma. Chemotherapy drugs, while ameliorative, can produce long-lasting side effects that potentially can affect survivor quality of life. Carboplatin is a common chemotherapy agent with known ototoxic side effects that is used in the treatment of retinoblastoma (Rodriguez-Galindo et al., 2003). The potential for carboplatin-induced hearing loss is of concern to the medical professional, given that retinoblastoma is often diagnosed in early childhood and children with retinoblastoma have visual impairments. This chapter will outline the mechanisms underlying carboplatin ototoxicity. The extent of knowledge concerning the pathophysiology of carboplatin-induced hearing loss will …

Monitoring Carboplatin Ototoxicity With Distortion-Product Otoacoustic Emissions In Children With Retinoblastoma, Shaum Bhagat, Johnnie Bass, Stephanie White, Ibrahim Qaddoumi, Matthew Wilson, Jianrong Wu, Carlos Rodriguez-Galindo

Faculty Publications

ObjectiveCarboplatin 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 …
