fNIRS, Listening Effort, and Motivation
Hearing LossThe purpose of the current study is to measure oxygenation in the PFC using fNIRS in a sample of older adults with hearing loss. Participants will be instructed to listen to sentences in noise at a challenging signal-to-noise-ratio, and to indicate what they heard using a closed-set response interface. Participants will complete 4 sessions: a training session, and a session for each condition. During each test session, participants will be instructed to listen to at least 100 sentences. Oxygenation, response times, and listening accuracy will be measured throughout.
Non-linear Frequency Compared to Conventional Processing in Patients With and Without Cochlear Dead...
Sensorineural Hearing LossBilateral1 moreThe investigators are interested in an additional hearing aid feature called non-linear frequency compression (NLFC). This aims to improve audibility of high frequency sounds by converting them into lower frequencies and has been shown to benefit those with moderate-severe sensorineural hearing loss (SNHL). Cochlear dead regions (DRs) are areas of the inner hearing organ (the cochlea) where there is little or no function and are commonly found in regions responsible for detecting high pitched (frequency) sounds. Not all people with hearing loss have DRs. The investigators would like to determine whether based on the presence or absence of DRs, patients with moderate-severe SNHL perform better or prefer their hearing aids programmed conventionally, or with NLFC activated. To do this, two participant groups will be created based on findings from the threshold equalising noise (TEN) test which identifies cochlear DRs. Two participant groups will be created; one group with DRs and one group without DRs. All participants will receive two hearing aids and will wear these programmed conventionally for ~six weeks and with NLFC activated for ~six weeks in a counterbalanced manner. Following each condition, participants will complete a questionnaire and various speech tests will be performed. This involves participants repeating sentences, words or speech sounds they hear from a speaker in quiet and in the presence of background noise. Individuals' scores will be calculated for each test and their performance when NLFC was activated and deactivated will be compared. This will be analysed alongside the questionnaire data to compare the 'DR' and 'no DR' group in both conditions. Findings may help to determine whether NLFC should be activated for all moderate-severe SNHL patients, or just those with DRs, helping clinicians to optimise hearing aid settings for patients.

Deafness; Sensoneural Single SidedConductive Hearing Loss1 moreThe aim of this clinical investigation is to investigate the subject´s overall preference, hearing performance and self-reported assessments with the Investigational device and its precursor Sound Processor (Comparator) after 6 weeks in subjects with conductive/mixed hearing loss or Single Sided Deafness, (SSD).
Training Language and Literacy for Children Who Use CIs
Hearing LossSensorineuralThis study aims to determine the effectiveness of computer games to improve language and literacy outcomes for children who have hearing loss. Children will be assigned to one of four conditions: phonological awareness training, working memory training, phonological awareness + working memory training, or active control.
Adaptation of a Rehabilitation Program for Prosody and Its Application on Egyptian Hearing Impaired...
Hearing Impaired ChildrenProsody is the melody and rhythm of speech, it is used to refer to the supra segmental aspects of speech including pitch, loudness and duration. Variations in these features achieve different prosodic functions and are perceived by the listener as meaningful changes. The role of prosody in language acquisition and effective communication is documented in research. Nevertheless, prosodic intervention in children with hearing impairment received less attention compared to other speech and language areas. The aim of this study is to adapt the "prosody treatment program", an evidence based rehabilitation program, and to detect the efficacy of its activities in improving the prosodic skills of Egyptian hearing impaired children. The "prosody treatment program" is an evidence-based practice targeting receptive and expressive prosodic skills in addition to speech production, intelligibility, pragmatics and phonology. The program is applied using a systematic approach of providing cues following the principles adapted from dynamic temporal and tactile cueing (DTTC) for speech motor learning to help accelerate the child's learning of the prosodic skills targeted in this program. The program was translated to Arabic and adapted to be suitable for the Egyptian children.
