Permanent childhood hearing impairment (PCHI) represents the most frequent sensory pathology at birth. PCHI has a relevant psychological impact on the life of both the affected children and their families. Thus, the aim of this work is to explore the degree of parental distress felt by mothers of a deaf or hard-of-hearing child, to determine if this stress is associated with variables related to the children’s health (e.g., the severity of hearing loss, presence of other conditions, difficulty with treatment options, difficulty with rehabilitation) or family characteristics such as socio-economic and educational status. The study used the Parenting Stress Index–Short Form (PSI-SF) questionnaire administered to mothers. The results were analyzed in relation to variables such as parents’ education level, number of children, severity of hearing loss, presence of other chronic conditions, presence of cognitive delay, familiarity with hearing loss, time of diagnosis, use of prosthetics, and start in a rehabilitation program. The data indicate a correlation between maternal stress levels and low-educational levels, as well as the presence of congenital infections and cognitive delay. These results highlight the need for a comprehensive physical and psychological approach for hearing-impaired children, as stress factors can affect the adherence to effective rehabilitation.

Background/Objectives: Bimodal stimulation (BS), which combines the use of a cochlear implant (CI) in one ear and a hearing aid (HA) in the opposite ear, is an established strategy to treat hearing loss by exploiting the unique capabilities of each device. CIs stimulate the auditory nerve by bypassing damaged hair cells, while HAs amplify sounds by requiring a functional hearing residual. The aim of this systematic review is to investigate the advantages and disadvantages of BS such as speech perception in noise. Methods: We examined clinical studies published from October 2020 to July 2024, following the PRISMA guidelines, focusing on the advantages and disadvantages of BS on speech perception in noise in adulthood. Results: BS in adult patients significantly improves speech perception in quiet and noisy environments, especially for those with increased residual hearing. Unilateral CIs and BS perform similarly in quiet conditions, but BS significantly improves speech discrimination in noisy environments if loudness between the two devices is appropriately balanced. Conclusions: Directional microphones and programming software are new technologies that succeed in reducing environmental noise and improving verbal perception outcomes, although their features in the literature are controversial. In addition, the individuals using BS may face temporal mismatches mainly due to differing device latencies, affecting sound localization. Compensating for these mismatches can enhance localization accuracy. However, modulated noise remains a significant obstacle to verbal perception in noise. Valuable assessment tools such as music tests provide further information on hearing performance and quality of life. More research is needed to define certain selection criteria.
