title: Audiological evaluation in employees exposed to noise in a public hospital

description: Purpose to characterize and to compare the hearing of employees of a public hospital exposed to maximum occupational noise levels above and below 85dB(A). Methods this clinical study selected 39 workers of a public hospital, divided according to the level of noise exposure: 20 subjects with maximum exposure levels above 85dB(A) (Group 1) and 19 individuals with maximum exposure levels below 85dB(A) (Group 2). Basic audiological evaluation, transient and distortion product otoacoustic emissions were carried out. Results both groups presented normal hearing thresholds. However, 87.5% in Group 1 and 60.5% in Group 2 showed absent responses in transient evoked otoacoustic emissions, with statistical difference. Group 2 showed higher signal/noise ratios also in distortion product otoacoustic emissions, and only the frequency of 6 kHz was abnormal in both groups. Conclusion sound pressure levels and noise exposure time did not influence in pure tone thresholds. The higher the sound pressure level and the longer the exposure time, more altered the otoacoustic emissions, indicating cochlear dysfunction.

title: Temporal resolution hearing in menstrual migraine

description: Purpose to verify auditory behavior of temporal resolution in women with Menstrual Migraine. Methods 40 women had participated, age between 18 to 31 years, 20 of them had presented menstrual migraine (study group) and 20 had not (control group). All of them were submitted to procedures which are part of an audiology’s routine. These procedures were made to characterize the peripheral hearing and to exclude people with hearing loss. They were also requested to answer a questionnaire elaborated for the researcher and submitted to the test Gap in noise. These procedures were carried out both in the precocious follicular phase and in the delayed luteal phase for volunteers who did not use any type of contraceptive, because in these periods the levels of the female hormones are higher and similar to those that used contraceptive. Results in the group of study, the values for the threshold gap and the percentage of rightness, regarding to the left ear were significant and statistically different relative to the control group. Within the right ear, the results were similar considering the two groups. Conclusion the temporal resolution in women with menstrual migraine, measure in a specific noise segment, regarding to the right ear, was similar for women without this complain, while in the left ear, the average of thresholds gap were different and those with migraine had the worst thresholds.

title: Air and bone-conduction frequency-specific auditory brainstem response in neonates with normal hearing

description: Purpose to determine the minimum response and the latency of V wave in the Frequency-specific auditory brainstem responses (FS-ABR) in normal hearing neonates at the frequencies: 0.5, 1, 2 and 4 kHz by air and bone conduction and to determine normative values. Methods normal hearing neonates were assessed with FS-ABR at 0.5, 1, 2 and 4 kHz, air and bone conduction. Twelve ears were assessed in each frequency, totalizing 18 neonates. Results analysis considered the latency and the presence of wave V until 20 dB nHL in air and bone conduction, for four intensities. Results it was observed an increase of wave V latency with the decrease of intensity, and greater latencies at lower frequencies in both air and bone conduction. Nevertheless, there was no difference between the latencies at 0.5 and 1 kHz with strong intensity stimuli in both conditions, contrasting to literature findings. Considering air conduction, wave V was present at 0,5 kHz at 30 dB nHL in all ears and at 1 kHz 11 ears (91,66%) presented it at 20 dB nHL. All subjects (100%) presented responses to the other frequencies at 20 dBn HL. Considering bone conduction, all subjects presented wave V at 20 dB nHL in all frequencies. Conclusion the found values can be used in clinical practice in order to guide the differential diagnosis of hearing loss, complementing the evaluation as for hearing neonates.

title: Speech recognition in ski slope sensorineural hearing loss

description: Purpose to determine which aspects of the audiometric configuration influence speech recognition in ski slop sensorineural hearing loss. Methods a survey of hospital records of patients treated at the Hearing Health Care in the period from March to July 2011 was performed selecting individuals above 18 years old and ski slop sensorineural hearing loss from mild to severe degree, with difference between the means of the frequencies of 0.25 to 2 kHz and 3-8 kHz greater than 15 dB HL. The sample of the study consisted of 30 patients (55 ears), 19 men and 11 women, aged between 26 and 91 years. Based on audiological evaluation, tests of speech recognition were correlated with different average hearing thresholds, including frequencies from 0,5 to 4 kHz. Furthermore, the differences in auditory thresholds between octave frequencies was studied and its impact on speech discrimination. Results excellent correlation was found between the mean thresholds from 0,5 to 4 kHz with speech discrimination, this correlation being stronger with the inclusion of the frequencies of 3 and 4 kHz in tone average. However, increasing the difference in hearing threshold between octaves of frequencies, which implies a ski slop, did not interfere significantly on tests of speech recognition. Conclusions based on the results of this study, we can conclude that the frequencies of 3 kHz and 4 kHz contribute to the speech intelligibility.

title: Effects of the mp3 player on hearing

description: Purpose to investigate if there is damage and the extent of even using MP3 player. Methods to get the best results on the extension of this harm, in addition to the Distortion Product Otoacustic Emission, the groups were also evaluated with Transient Evoked Otoacustic Emissions. They were asked to listen to MP3 players and divided into two groups, 15 of them belonged to the controlled group (medium intensity of 85 dBNA) and the others in the analysis group (medium intensity of 110 dBNA). The method used for the analysis was inferencial (test “t” to parallel samples). Results the results showed that the controlled group has presented alterations in the frequency of 1,5kHz in the Transient Evoked Otoacustic Emissions and 6 kHz in the frequency of Distortion Product. While the study group showed alteration in the frequency of 2, 3, 4 kHz and also in the medium amplitude of all frequencies in the Transient Evoked Otoacustic Emissions and in the frequencies of 3 and 6 kHz in the Distortion Product. Conclusion this study confirmed that those people exposed to intense noise, generated by the MP3 Player, showed a significant loss of their hearing extension, indicating a temporary change in their cochlea cells that might turn into a permanent loss when continuously exposed to it.
