This study examined the effects of sound-field amplification (SFA) use for children who are deaf or hard of hearing (DHH) with additional diagnosed conditions enrolled in preschool and first and second grades in a rural district. Four focus children who are DHH with additional diagnoses were matched with hearing peers and observed for attending behaviors and latency in compliance to following routine directions with introduction of SFA. The study used a single-case multiple probe across participants design. All participants demonstrated improved attending behaviors and compliance to directions with SFA, with the focus children who are DHH with additional diagnoses showing stronger results than their hearing peers. Teachers indicated SFA was beneficial to the children who are DHH and they would use it again. SFA is an effective strategy to improve access to educational opportunities by increasing attending behaviors and promoting participation for children who are DHH with other diagnoses in special and general education preschool and first and second grades.

有听力障碍和其他诊断的幼儿：声场放大的影响

本研究调查了使用声场放大 (SFA) 对聋哑或听力障碍 (DHH) 儿童的影响，这些儿童患有额外的诊断疾病，在农村地区就读于学前班和一二年级。四个有额外诊断的 DHH 焦点儿童与听力同龄人相匹配，并观察他们在遵循常规指示并引入 SFA 的情况下的参与行为和潜伏期。该研究使用跨参与者设计的单案例多调查。所有参与者都表现出改善的参与行为和遵守 SFA 的指示，具有额外诊断的 DHH 的焦点儿童显示出比听力同龄人更好的结果。老师们表示SFA对DHH的孩子有好处，他们会再次使用它。
