Filter by:The language outcome of children receiving cochlear implantation to address bilateral sensorineural hearing loss is more variable than that of typical hearing children. The research is focused upon development of neural predictive models based upon brain imaging to forecast language after cochlear implantation on the individual child level. The long-term goal is improving children's language by using predictive models to enable a custom "predict to prescribe" approach to intervene with more effective behavioral therapy for children at risk to develop poorer language. The investigators previously developed models for short term language outcome of English-learning implanted children. The aims of this study are to 1. Develop models able to predict long term outcome for English- learning and Spanish-learning children; and 2. To evaluate whether English-learning children predicted to achieve lower language based on the investigators' previously constructed models can demonstrate significant gains from Parent Implemented Communication Treatment (PICT). PICT is an intensive parent education program about strategies to improve children's communication.
Subjective listening effort and objective speech intelligibility will be evaluated with a new generation of a Phonak BTE (Behind-The-Ear) hearing aid.
Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy (TFS4) to a default fitting strategy (FS4) for the speech recognition in noise. Secondary objectives: Comparison of TFS4 to FS4 for speech recognition in quiet. Comparison of TFS4 to FS4 for the auditory skills experienced by the subject.
The purpose of this study is to investigate the effect of nonlinear signal processing algorithms on speech perception.
The investigators evaluated patients older than 6 years old, with severe hearing loss, cochlear implant wearers, able to perform a series of tests (TUISE, the pitch discrimination test, the melody discrimination test, VAS) to assess the skills of perceiving spectral components of music and understanding emotional states of language investigating the relationship between musical ability, pitch discrimination and paraverbal language comprehension.
The cochlear implant represents the gold standard in the treatment of children with bilateral severe-profound deafness. However, the current Italian and international guidelines do not address the issue of rehabilitation and how the different rehabilitation methods should be applied in relation to the different clinical pictures. The aim of this study is therefore to describe which methods are used today in the rehabilitation of deaf children with cochlear implants followed at the Phoniatrics and Speech Therapy service of the A. Gemelli Polyclinic Foundation. The creation of a questionnaire directed to the speech therapist who treats the specific patient is available in order to collect data concerning the characteristics of the setting and the rehabilitation method in relation to the most applied methodologies, i.e. Auditory-verbal therapy, oral-cognitive therapy, bimodal method and the Drežančić method.
Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy with synchronization between HA and CI (ABFS) to a tonotopy based fitting strategy without synchronization (ABFnoS) for the accuracy of sound localization. Secondary objectives: Comparison of ABFS to ABFnoS for the bias of sound localization. Comparison of ABFS to ABFnoS for speech perception in noise. Comparison of ABFS to ABFnoS for the auditory skills experienced by the subject.
The aim of this proposed project is to understand whether direct to consumer (DTC) hearing aids programmed to individual hearing losses, can reduce listening effort for effective communication. If DTC aids can provide benefits beyond amplification, then they could be an affordable option to reduce barriers to care and improve hearing aid uptake in adults with hearing loss.
Sudden sensorineural hearing loss is one of the most common emergencies in otorhinolaryngology, and its incidence is increasing year by year and tends to be younger. At present, the pathogenesis of sudden deafness is not clear and the individual treatment effects vary significantly. In order to break through this specific treatment bottleneck, this project pioneered the clinical application of the co-regulator nicotinamide adenine dinucleotide (NAD+) in the treatment of sudden deafness. Therefore, this project intends to use pure tone audiometry, speech audiometry, tinnitus disability scale THI, tinnitus subjective visual analog score method VAS, ear fullness subjective visual analog score method VAS for data analysis, and explore the safety of coenzyme I for injection on sudden deafness and efficacy assessment.
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. Based on the conclusions of the first study, we have identified areas that require further analysis and testing prior to implementing of the proposed frequency response curve into our products. This study aims to investigate the current freqeuncy response curve in the manufacturer's products to variations of these curves to determine if hearing aid users prefer the variations over the manufacturer's standard curve.
