Introduction The Sustained Auditory Attention Ability Test (SAAAT) is an instrument used to assess sustained auditory attention in children. Difficulties related to this ability are not unique to children alone, as adults have been observed to present with the same deficits. Therefore, there is a need to adapt instruments like the SAAAT and provide reference values for adults. Objective To assess adult performance on the SAAAT. Methods Approved by the Human Research Ethics Committee under n° 034/2011. The sample consisted of 30 participants aged between 18 and 30 years old (average age = 24.2 years old), female and male. The inclusion criteria were: peripheral hearing within normal limits, type A tympanometric curve, and no attention-related complaints. The participants were submitted to Tonal Audiometry, Logoaudiometry, Immitanciometry and to the SAAAT. Results The following mean values and standard deviations (SD) were observed: inattention = 1.7 (SD = 2.2) and impulsivity = 0.8 (SD = 0.9) error types. For the SAAAT, the mean value for the total error score was 2.4 (SD = 2.6), and for the decrease in vigilance, it was 0.3 (SD = 0.5). When comparing the performance of adults and children, a statistically significant difference was observed for inattention (p = 0.000) and impulsivity (p = 0.001) error types, as well as in the total error score (p = 0.000) and in decreased vigilance (p = 0.0003). Conclusion The performance of adults in the SAAAT differed from the children's parameters, since adults showed lower scores in all variables of the instrument.

This study aimed to assess temporary and permanent auditory effects associated with occupational coexposure to low levels of noise and solvents. Cross-sectional study with 25 printing industry workers simultaneously exposed to low noise (<80 dBA TWA) and low levels of solvents. The control group consisted of 29 industry workers without the selected exposures. Participants answered a questionnaire and underwent auditory tests. Auditory fatigue was measured by comparing the acoustic reflex threshold before and after the workday. Workers coexposed to solvents and noise showed significantly worse results in auditory tests in comparison with the participants in the control group. Auditory brainstem response results showed differences in III–V interpeak intervals (p = 0.046 in right ear; p = 0.039 in left ear). Mean dichotic digits scores (exposed = 89.5 ± 13.33; controls = 96.40 ± 4.46) were only different in the left ear (p = 0.054). The comparison of pre and postacoustic reflex testing indicated mean differences (p = 0.032) between the exposed (4.58 ± 6.8) and controls (0 ± 4.62) groups. This study provides evidence of a possible temporary effect (hearing fatigue) at the level of the acoustic reflex of the stapedius muscle. The permanent effects were identified mainly at the level of the high brainstem and in the auditory ability of binaural integration.
