“…Interruption of sleep and rest, caused many times by noise, may negatively influence the child's health recovery process 15,16 . For a newborn, staying in a noisy environment for over 48 hours is considered a risk factor for hearing disorders 17 .…”

Purpose: to assess the noise level in different environments of a public hospital and to analyze its effects on employees from reporting complaints. Methods: a quantitative, descriptive and cross-sectioned study. To survey data, we used a Minipa® decibelimeter adjusted in the range 40-130 decibels positioned in different hospital departments in different shifts for a week to evaluate noise levels and an adapted questionnaire that was applied to employees. Results: the level of noise introduced minimum of 52.5 decibels in the Intensive Care Unit (NICU) and a maximum of 85 decibels in the women's ward with a significant difference between the different days of the week during the same turn. The same occurred in the emergency room, but did not show significance in other sectors. Employees feel discomfort to loud sounds, 74.4%, and 35.5% feel sick after hours due to stress caused by noise that is produced by multiple devices combined with the sounds of alarms, works, visits and schedules conversation between the hospital staff. Conclusion:noise levels are above the recommended levels in different sectors and professionals manifest discomfort and tinnitus before and after their exposure.

Objective: Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Womens Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors.Methods: 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The result was considered normal when the newborn showed response to a 35dBNA signal bilaterally. The prevalence of AABR impairment and the odds ratio were analyzed with a 95% confidence interval using bivariate analysis. To identify the independent risk factors for hearing alterations, multivariate analyses were used with logistic regression.Results: The prevalence of AABR impairment was 10.2%, of which 5.3% was unilateral and 4.9% bilateral. From the multivariate analyses, the following observations were made: family history of congenital hearing loss (OR = 5.192; p = 0.016), craniofacial deformity (OR = 5.530; p < 0.001), genetic syndromes associated with hearing loss (OR = 4.212; p < 0.001), weight below 1,000 g (OR = 3.230; p < 0.001), asphyxia (OR = 3.532; p < 0.001), hyperbilirubinemia (OR = 4.099; p = 0.002) and use of mechanical ventilation (OR = 1.826; p < 0.031) were the indicators that best characterized the group at risk for hearing impairment. Conclusions:The prevalence of hearing impairment using AABR is high. Therefore, it is essential for all newborns who present isolated or associated risk factors to undergo hearing screening in situations in which it is not possible to have universal hearing screening.J Pediatr (Rio J). 2006;82(2):110-4: Newborn, diagnosis, hearing loss. ResumoObjetivo: Avaliar a prevalência de alterações auditivas em recém-nascidos internados na unidade de terapia intensiva e cuidados intermediários do serviço de neonatologia do Centro de Assistência Integral à Saúde da Mulher, Faculdade de Ciências Médicas, Universidade Estadual de Campinas, e analisar os fatores de risco associados.Métodos: Foram avaliados 979 recém-nascidos no período de janeiro de 2000 a janeiro de 2003, utilizando-se a audiometria automá-tica de tronco encefálico (AABR), com aparelho ALGO-2e color -Natus. O resultado foi considerado normal quando o recém-nascido apresentou resposta para 35 dBNA bilateralmente. Foi analisada a prevalência de AABR alterada e odds ratio com intervalo de confiança de 95% em análise bivariada. Para identificar os fatores de risco independentes para AABR alterada, foi feita análise múltipla com modelo de regressão logística.Resultados: A prevalência de alteração no AABR foi de 10,2%, sendo 5,3% unilateral e 4,9% bilateral. Pela análise multivariada, observamos que: antecedente familiar (OR = 5,192; p = 0,016), malformação craniofacial (OR = 5,530; p < 0,001), síndrome genética (OR = 4,212; p < 0,001), peso menor que 1.000 g (OR = 3,230; p < 0,001), asfixia (OR = 3,532; p < 0,001), hiperbilirrubinemia (OR = 4,099; p = 0,002) e uso de ventilação mecânica (OR = 1,826; p < 0,031) foram os in...

“…19 Another study assessed newborns weighing under 1,500 g with distortion product otoacoustic emissions and found a prevalence of 6.3% for hearing loss. 20 Although the data in the literature show variable results, the prevalence we observed is above the average, Since birthweight is a continuous variable, it was separately analyzed in the following categories: < 1,000 g, from 1,000 to 1,500 g, from 1,501 to 2,500 g and > 2,500 g. Newborns weighing > 2,500 g were considered to be at less risk, and were considered as the reference category, with which the other categories were compared.…”
