Filter by:The purpose of this study is to learn more about how bilingual individuals process sound in challenging listening environments and how testing language may impact results on auditory processing assessments. Auditory processing evaluations assess specific auditory skills necessary to hear and understand complex auditory signals, but many of these tests rely heavily on language. This poses an issue for individuals with native languages other than English because the test results may not clearly identify whether performance is due to an auditory processing problem or to the language used in the test materials. This study aims to identify whether auditory processing performance differs in Spanish-English bilinguals based on the language of the test materials used (English vs. Spanish). Ultimately, the results of this study may aid in more accurate diagnoses and treatment of auditory processing disorders in bilingual individuals.
Rehabilitation of dyslexic children with (cental) auditory processing disorder. The first group will receive the proposed program the arabic version of differential processing training program and the control group will receive the computer based auditory traing program (CBAT).
The purpose of this preliminary study is to help clarify our hypotheses for the longitudinal study by investigating the relationship between vocal cord paralysis and central auditory processes and thus the interpretation of auditory inputs into the central nervous system.
Older people experience great difficulty understanding speech, especially accented English, and this problem is expected to increase with the influx of immigrants who provide services to the elderly population. The research examines the underlying factors that contribute to older listeners' difficulty understanding accented speech, including those associated with age-related hearing loss, changes in processing in auditory pathways in the brain, and general cognitive decline. The investigation also evaluates the efficacy of training strategies to improve understanding of accented English by older people. Outcomes of this research are expected to improve communication between senior citizens and those with whom they interact daily, and thereby improve quality of life for the older segment of the Nation's population.
This study aimed to evaluate long term benefits in speech reception in noise, after daily 10 week use of an assisting listening device (personal frequency-modulates systems) , in non-aphasic stroke patients with auditory processing deficits.
Purpose: A research project will be conducted at the ADD ("Attention Deficit Disorder") Centre and Biofeedback Institute of Toronto to evaluate the feasibility of the Listening Project Protocol (LPP) intervention in individuals with difficulties with autonomic and/or behavioral regulation. The LPP is designed as a "neural exercise" to reduce auditory hypersensitivities, to improve auditory processing of speech, and to improve behavioral state regulation. These improvements should translate into increase feelings of safety and calmness, thereby promoting improvement in social behavior. Participants: 30 participants, males and females between ages 7-55 years, will be recruited for the study. Participants will be patients at the ADD Centre and Biofeedback Institute of Toronto. Procedures: Participants will be divided into 1 of 2 groups (1:1 ratio). Both groups will have a pre-intervention assessment #2, intervention, 1 week post intervention assessment and 1 month post intervention assessment. Group 2 will have an additional pre-intervention assessment session #1 (1 week previous to pre-intervention assessment #2) to assess the stability of the measures prior to starting the intervention. Pre-, post-, and 1 month followup assessment will include parent and/or self-report questionnaires, and measures of the individual's auditory processing ("SCAN"), affect recognition ("DARE" Dynamic Affect Recognition Evaluation), heart rate, prosody, "RSA" respiratory sinus arrhythmia (derived from non-invasive ECG recording), and middle ear transfer function ("MESAS" - Middle Ear Sound Absorption System).
A research project funded by the Reiss-Davis Child Study Center of Vista Del Mar (RDCSC/VDM) will be conducted on the Vista Del Mar campus of the RDCSC/VDM to evaluate the effectiveness of the Listening Project Protocol (LPP) in children who have difficulties with autonomic and behavior regulation in the classroom. The LPP is designed as a "neural exercise" to reduce auditory hypersensitivities, to improve auditory processing of speech, and to improve behavioral state regulation. The LPP uses acoustic stimulation to exercise the neural regulation of the middle ear structures to rehabilitate and to normalize the acoustic transfer function of the middle ear structures. The current study is being conducted to evaluate efficacy and feasibility of the LPP with emotionally disturbed and learning challenged young people and will use objective measures to evaluate changes in acoustic transfer function of the middle ears structures, auditory processing skills, physiological state regulation, sensory symptoms, and academic pre and post testing.
Auditory Processing Disorder (APD) is a disorder where the functions of the ear are normal, but the person has difficulty identifying or discriminating sounds and experiences listening difficulties in noise. Remote Microphone Hearing Aids (RMHAs) are wireless listening devices that pick up the speaker's voice and transmit it to a receiver in the listener's ear. In this way, the negative effects of ambient noise, distance from speaker and reverberation are reduced. The research questions are whether RMHAs improve classroom listening, listening in noise performance, listening in spatialised noise and auditory attention, in children with APD. We hypothesize that RMHA use will lead to improved classroom listening and improved speech-in-noise skills after 6 months of RMHA use. Additionally, we hypothesise that listening in spatialised noise and attention skills will remain unchanged following the intervention period. Twenty-six (26) children aged 7-12 with a diagnosis of an APD from the Great Ormond Street Hospital Audiology clinic were included in the study.
The investigators assume that cochlear implants in this indication are not only effective but also cost-effective. The investigators' experimental protocol relies on real life therapeutic strategy, where a cochlear implant may be proposed once CROS and bone conductions systems have failed. Thus, all subjects enrolled in our study will try CROS and bone conduction devices. If these trials are ineffective, the remaining subjects will be randomized between two arms (cochlear implantation vs 6 months abstention followed by cochlear implantation). A comparative cost-utility analysis between the two arms, of medical consequences measured in terms of quality of life will identify a preference for a strategy. Specific binaural hearing measurements with respect to each treatment option (abstention, CROS, bone conduction device, cochlear implant) will also be collected.
The current study aimed to examine the effectiveness of a Computer-based auditory training (CBAT) intervention for children with Central Auditory Processing Disorder (CAPD) by comparing the changes in auditory processing (AP) and functional listening skills of these children immediately post-intervention, to that of the untrained controls. The AP skills of the trained group were evaluated again at 3 months post-intervention to examine the sustainability of any improvements made from the CBAT intervention. I hypothesised that after intervention, children from the auditory training (AT) group would improve in their AP skills, and that improvement would be greater than the changes in AP skills of those untrained controls. I also hypothesised that the improvement made from the intervention would sustain for at least 3 months after the end of intervention. Finally, I examined if the training outcomes are predictable from any underlying factors such as the initial AP, language, or cognitive skills of these children.
