Abstract Background Lipreading is considered an important skill that varies considerably among normal-hearing (NH) and hearing-impaired (HI) children. It is well known that normal-hearing children use audition as the primary sensory modality for speech perception, whereas HI children use lipreading cues as the primary sensory modality for speech perception. Moreover, speech perception is a multisensory process that involves attention to auditory signals as well as visual articulatory movements, and the integration of auditory and visual signals occurs naturally and automatically in normal individuals of all ages. Most researches proved that lipreading is a natural and important skill needed for language acquisition in HI children. Lipreading also helps HI children to perceive speech, acquire spoken language, and acquire phonology. In the Arabic language, tools are deficient for assessing the lipreading ability for HI children, so this study was conducted to develop a test suitable for assessing the lipreading ability of hearing-impaired children among Arabic-speaking countries. The constructed lipreading test was administered to 160 Arabic-speaking Egyptian children including 100 typically developing NH children and 60 HI children. Participants’ responses were statistically analyzed to assess the validity and reliability and to compare the lipreading ability between the NH and HI children. Ranks of percentiles were established to provide an estimate of the lipreading ability in children. Results Statistically significant differences were found between the normal-hearing and HI children as regards all subtotal and total scores of the Arabic lipreading test, with good validity and reliability of the test. Conclusions The Arabic lipreading test is a valid and reliable test that can be applied to assess the lipreading ability among Arabic-speaking children with HI.

Acoustic Conditions

Hearing-impaired people need more stringent acoustic and noise requirements than normal-hearing people in terms of speech intelligibility and listening effort. Multiple guidelines recommend a maximum reverberation time of 0.4 s in classrooms, signal-to-noise ratios (SNRs) greater than 15 dB, and ambient noise levels lower than 35 dBA. We measured noise levels and room acoustic parameters of 12 classrooms in two schools for hearing-impaired pupils, a dormitory apartment for the hearing-impaired, and a church mainly for the hearing-impaired in the Republic of Korea. Additionally, subjective speech clarity and quality of verbal communication were evaluated through questionnaires and interviews with hearing-impaired students in one school. Large differences in subjective speech perception were found between younger primary school pupils and older pupils. Subjective data from the questionnaire and interview were inconsistent; major challenges in obtaining reliable subjective speech perception and limitations of the results are discussed.
