Abstract Introduction The audiological evaluation has the main objective of determining the integrity of the auditory system. Pure tone audiometry is a standardized behavioral procedure that aims to investigate auditory thresholds to describe auditory sensitivity. Despite being recognized since the mid-1960s, high frequency audiometry is still little used and explored in clinical practice, and its use is more considered as an audiological monitoring tool or as a research tool. Objective To analyze the audiological thresholds of high frequency audiometry in normal hearing individuals, and to verify the predictive capacity of age in the auditory thresholds of high frequency audiometry. Methods This is a retrospective, cross-sectional, and quantitative study that was approved by the Research Ethics Committee under number 5.039.583/21. The procedures were: clinical evaluation, pure tone audiometry, acoustic immittance measurements, and high frequency audiometry. All data collected from the exams were tabulated in an Excel spreadsheet and analyzed using appropriate statistical tests in the Statistical Package Social Sciences software. Results A total of 980 medical records were analyzed. The right and left ears presented similar tonal hearing thresholds for the frequencies of 12 kHz and 16 kHz. The threshold variance of 29.8% in the 12 kHz frequency can be explained by the variance of age, while, for the frequency of 16 kHz, this percentage is of 46.4%. Conclusion For 12 kHz hearing thresholds, an increase of 1 year leads to a 0.66 dBHL increase in hearing threshold. For 16 kHz hearing thresholds, an increase of 1 year leads to a 1.02 dBHL increase in hearing threshold.

RESUMOObjetivo Caracterizar e analisar o perfil dos usuários atendidos em um Grupo de Avaliação e Prevenção de Alterações de Linguagem (GAPAL) de uma clínica-escola.Métodos Pesquisa retrospectiva de banco de dados do GAPAL, do primeiro semestre/2002 ao primeiro semestre/2013. Foram analisados 261 usuários, quanto à idade, gênero, procedência, encaminhamentos e queixas apresentadas.Resultados Houve maior incidência de queixas relacionadas à linguagem no gênero masculino e na faixa etária de 25 a 30 meses de idade. A cidade com maior procedência de usuários foi Campinas. Quanto aos encaminhamentos, a maior parte foi realizada por profissionais de saúde, em sua maioria pediatras, sendo o relato mais ocorrente o de queixa de atraso de linguagem.Conclusão O estudo possibilitou a caracterização da população assistida, reiterando a importância de ações de promoção e prevenção das alterações de linguagem, principalmente junto às famílias. Também evidenciou limitações e dificuldades quanto ao registro dos dados, indicando a necessidade de readequação dos registros para nortear ações de (re)organização e gestão dos serviços na clínica de linguagem, tendo em vista o aprimoramento das ações de fonoaudiologia para esse grupo populacional.

ABSTRACTPurpose To characterize and analyze the population profile of an evaluation and prevention group of language disorders (GAPAL) in a clinic school.Methods It was a retrospective study from related database of GAPAL from the period of the 1st half/ 2002 through 1st half/ 2013. 261 users were analyzed by age, gender, hometown, referrals and complaints.Results It was found a higher occurrence of complaints related to language in males and aged 25-30 months. The city of origin of most users was Campinas. In terms of referrals, the major part of them was made from health professionals, mostly pediatricians, who reported language delay.Conclusion The study enable to characterize the population who are assisted by this service and reaffirm the importance of language promotion and prevention actions, especially with families. However, this analysis also showed limitations and difficulties in the recording of data, ponting the need to readequate database, so they can be taken as a guide for (re) organization actions and management of services in clinical speech and language with a view to the improvement of Speech and Language Pathology for this population group.
