“…Moreover, minimal to mild sensorineural hearing loss was observed in 52.77% of pSS patients (n = 19) according to pure tone averages. According to a study on very high frequency hearing thresholds in normal-hearing adults (9000-12,500 Hz), 30 subjects (83.33%) had high frequency hearing loss in the current study [18].…”

Background/aim: Autoimmune diseases are a remarkable issue for researchers due to their adverse effects on the auditory system, but for primary Sjögren's syndrome (pSS) there is little research on the comprehensive audiological findings in literature. The main objective of this study was to investigate the medial olivocochlear efferent functions of subjects with pSS and to examine the audiological findings. Materials and methods: The study included 36 subjects with pSS and 36 healthy subjects. All the subjects underwent testing including pure tone, speech, and high frequency audiometry; tympanometry and acoustic reflexes; distortion product otoacoustic emissions (DPOAE); and suppression of DPOAE. Results: The hearing thresholds of the pSS group were higher than those of the control at all frequencies (P < 0.001). Minimal to mild sensorineural hearing loss was observed in 52.77% of all the subjects with pSS. Additionally, all of the subjects had type A curve tympanograms, but the static compliances of the pSS group were lower and the acoustic reflex thresholds were higher than in the control (P < 0.001). In suppression levels of DPOAE, no statistically significant difference was found between the groups (P > 0.05). Conclusion: The study indicates that because of obtaining normal suppression levels in DPOAE, the medial olivocochlear efferent system is functional in pSS. However, there is a need for more tests, including auditory brainstem response, to evaluate the afferent auditory system in pSS.

“…Other studies followed respondents in the age group of 18–31 years, with age intervals ranging from 11 to 15 years [ 18 , 19 , 20 ]. Oppitz et al [ 21 ] used the largest age range. Kumar et al and Le Prell et al monitored the effect of personal listening devices (PLDs) [ 19 , 20 ].…”

“…Articles monitoring high-frequency hearing loss in unexposed individuals reported an increase in hearing thresholds with an increasing frequency as well as with increasing age [ 17 , 18 , 21 ]. In populations unexposed to workplace noise, significantly higher hearing thresholds were found at frequencies of 14 and 16 kHz, and these increased with age [ 17 , 20 ].…”

“…Oppitz et al found higher hearing threshold values in the right ear than in the left ear at 10, 11 and 14 kHz. At frequencies above 14 kHz, the progressive increase was proportional to the frequency and was bilateral (binaural), with threshold values increasing with age at all frequencies [ 21 ]. Barbosa de Sá et al found that the thresholds were similar in the left and right ears, with significant differences between the ears only being observed at 11 and 12 kHz, with the right ear being worse [ 18 ].…”

The WHO considers hearing loss to be a major global problem. A literature search was conducted to see whether high-frequency audiometry (HFA) could be used for the early detection of hearing loss. A further aim was to see whether any differences exist in the hearing threshold using conventional audiometry (CA) and HFA in workers of different age groups exposed to workplace noise. Our search of electronic databases yielded a total of 5938 scientific papers. The inclusion criteria were the keywords “high frequency” and “audiometry” appearing anywhere in the article and the participation of unexposed people or a group exposed to workplace noise. Fifteen studies met these conditions; the sample size varied (51–645 people), and the age range of the people studied was 5–90 years. Commercial high-frequency audiometers and high-frequency headphones were used. In populations unexposed to workplace noise, significantly higher thresholds of 14–16 kHz were found. In populations with exposure to workplace noise, significantly higher statistical thresholds were found for the exposed group (EG) compared with the control group (CG) at frequencies of 9–18 kHz, especially at 16 kHz. The studies also showed higher hearing thresholds of 10–16 kHz in respondents aged under 31 years following the use of personal listening devices (PLDs) for longer than 5 years. The effect of noise-induced hearing loss (NIHL) first became apparent for HFA rather than CA. However, normative data have not yet been collected. Therefore, it is necessary to establish a uniform evaluation protocol accounting for age, sex, comorbidities and exposures, as well as for younger respondents using PLDs.

“…Para esse estudo, foi realizado audiometria tonal (250Hz a 8kHZ) para descarte de qualquer perda auditiva e posteriormente audiometria de altas frequências (9kHZ a 20kHz), pois pesquisas mostram que indivíduos que apresentam zumbido podem já apresentar problemas de origem coclear, mesmo antes de manifestarem algum tipo de perda auditiva (BUZO;CARVALLO, 2013;TUGUMIA et al, 2016;VALIENTE et al, 2016). A avaliação audiológica tonal e de altas frequências é amplamente utilizada em estudos que avaliam a função auditiva, por serem procedimentos padronizado para demostrar a sensibilidade auditiva do indivíduo nas frequências de 125Hz a 20kHz (VALIENTE et al, 2016;OPPITZ et al, 2018).…”

The use of Low Level Laser in individuals with tinnitus and without hearing loss Introduction: Among the most common complaints within otorhinolaryngology and audiology clinics, tinnitus stands out as one of the most uncomfortable for the subject. There are several modalities for the treatment of tinnitus, with emphasis on pharmaceutical therapy, physiotherapy, psychotherapy, surgery, and among the possibilities of intervention, there is growing significance in the use of low level laser. Nevertheless, despite many articles in the international literature about this theme, there are several disagreements regarding the protocol of application and the efficacy of this treatment. Proposition: To verify the effect of laser therapy in individuals with chronic tinnitus symptom without hearing loss. Methods: The study was developed at the Centro Auditivo Ouvir-Bauru, with the acceptance of the Research Ethics Committee and patient acquiescence confirmed by signing the Informed Consent Term. Patients who suited the inclusion criteria were randomly set to Group 1: treated with low level laser and Group 2: treated with placebo laser. Anamnesis was applied with the individuals before the battery of tests and the data collected were registered in the individual's folder. after the interview, the audiological exams started, which included: tonal audiometry, high frequency audiometry, immittanciometry and acufenometry for hearing loss disposal, Tinnitus Handicap Inventory to measure the level of discomfort with tinnitus pre and post treatment and visual analogue scale to measure the level of discomfort with tinnitus pre and post laser application. The Laser Therapy protocol included 12 laser therapy sessions for Group 1 and placebo laser for Group 2, using 4J in the lingual vein in the red wavelength, 4J in the right and left tympanic membrane, in the red wavelength, and 9J in the right and left mastoid, at the infra-red wavelength. Results: the sample consisted of 20 patients, eight females and 12 males with the average of 54 yearsold. There was no statistical difference in function of the intervention group and the moment of evaluation for the high frequency audiometry and acuphenometry outcomes. The disadvantage of individuals with chronic tinnitus reduced significantly after the intervention, regardless of the intervention. It can be verified that the annoyance of individuals with chronic tinnitus decreased significantly with difference between the initial and final sessions, independently of the intervention group, but Group 1 presented a greater reduction than Group 2, independently of the moment of evaluation and the number of the session. Conclusion: It was concluded that individuals with chronic tinnitus reduced the disadvantage independently of the intervention group, and the level of discontentment with tinnitus in the initial sessions according to the final ones independently of the moment of evaluation and the intervention group. The group receiving laser therapy further improved the level of tinnitus dissatisfact...
