Newborn hearing screening program (NHSP) is a standard of care in many countries around the world. Its success to a great extent depends on professionals understanding of the program’s goals and the screening procedures. Hence, this study aimed to investigate the knowledge and attitudes of Malaysian healthcare professionals involved in NHSP. A cross-sectional survey study using a 25 items questionnaire was conducted on a purposive sample of healthcare professionals who worked in 30 Malaysian government hospitals that run NHSP. Four hundred and three questionnaires were distributed, only 138 completed questionnaires were analysed, yielding a response rate of 34.2%. Of the 138 healthcare professionals, 35 (25.4%) were paediatricians, 43 (31.2%) were ear, nose and throat (ENT) specialists, and 60 (43.5%) were nurses. In general, the study revealed that the ENT specialists scored significantly higher that the paediatricians and nurses on both knowledge and attitude. Although the majority of all three healthcare professionals (>75%) viewed NHSP as very important, yet many nurses and paediatricians (>70%) reported received limited information during their training in this area and felt uncomfortable in explaining about the whole hearing screening process to the parents. Despite the positive attitude towards NHSP, 22.5% of the healthcare professionals were not aware of the existence of the program. In conclusion, this study has demonstrated knowledge gap in NHSP among the healthcare professionals, but their positive attitudes could be an indication of a strong interest to learn more about NHSP. Therefore, there is a need to take urgent efforts to improve the knowledge of healthcare professionals on NHSP.

BACKGROUND AND OBJECTIVES: This study investigated the effect of ageing on speech perception in quiet and in noise, with noise directed from front, right and left. SUBJECTS AND METHODS: Sixty Malay native adults with normal or near normal hearing comprising of 20 young adults (21 to 39 years old), 20 middle aged (40 to 59 years old) and 20 older adults (60 to 74 years old) participated in this study. Their speech perception ability was measured using the Malay Hearing in Noise Test (HINT) in four test conditions; 1) in quiet (HINT Q), 2) with noise from front (HINT NF), 3) with noise from right (HINT NR), and 4) with noise from left (HINT NL). Reception thresholds for sentences (RTSs) were measured in each of the aforementioned conditions using an adaptive method. RESULTS: The results showed that, 1) genuine age-related decline was found in speech perception performance in HINT (NF), 2) hearing threshold was a major determinant differentiating speech perception performance for HINT (Q) and HINT (NL) conditions, and 3) speech perception performance for HINT (NR) was determined by both age and hearing threshold. CONCLUSIONS: This study suggests that, in older adults, while hearing thresholds affect speech perception in quiet, other factors such as central auditory processing and cognitive functions might be more important determinant factors for speech perception performance in noise.

BACKGROUND AND OBJECTIVES: Although ethnicity effect on wideband absorbance (WBA) findings was evident for adults, its effect on neonates has not been established yet. This study aimed to investigate the influence of ethnicity on WBA measured at 0 daPa from neonates with healthy middle ear functions. SUBJECTS AND METHODS: Participants were 99 normal, healthy, full-term newborn babies with chronological age between 11 and 128 hours of age (mean=46.73, standard deviation=26.36). A cross-sectional study design was used to measure WBA at 16 one-third octave frequency points from 99 neonates comprising of three ethnic groups: Malays (n=58), Chinese (n=13) and Indians (n=28). A total of 165 ears (83.3%) that passed a battery of tests involving distortion product otoacoustic emissions, 1 kHz tympanometry and acoustic stapedial reflex were further tested using WBA. Moreover, body size measurements were recorded from each participant. RESULTS: The Malays and Indians neonates showed almost identical WBA response across the frequency range while the Chinese babies showed lower absorbance values between 1.25 kHz and 5 kHz. However, the differences observed in WBA between the three ethnic groups were not statistically significant (p=0.23). Additionally, there were no statistically significant difference in birth weight, height and head circumference among the three ethnic groups. CONCLUSIONS: This study showed that Malays, Chinese and Indians neonates were not significantly different in their WBA responses. In conclusion, to apply for the ethnic-specific norms is not warranted when testing neonates from population constitute of these three ethnicities.
