Perception of the acoustic environment during COVID-19 lockdown in Argentina.

The COVID-19 pandemic has significantly modified the behavior of societies. The application of isolation measures during the crisis resulted in changes in the acoustic environment. The aim of this work was to characterize the perception of the acoustic environment during the COVID-19 lockdown of people residing in Argentina in 2020.

Hearing and Exposure to Music in Adolescents From Four Schools of Córdoba, Argentina.

Purposes The aims of this study are (a) to characterize the hearing of adolescents from four schools of Córdoba, Argentina, through the analysis of conventional and extended high-frequency audiometric thresholds and otoacoustic emissions (OAEs) and (b) to analyze the association between the mentioned hearing tests and exposure to music. Method It was a cross-sectional correlational descriptive study. Hearing thresholds (250-16000 Hz), transient evoked OAEs, and distortion product OAEs were evaluated in 225 adolescents (450 ears) aged 14 and 15 years.

[Auditory closure according to central auditory processing and psycholinguistic skills in adolescents.].

Introduction: The process of auditory closure is defined as the ability to complete distorted or missing parts of the acoustic signal and recognize the message in its entirety, is executed daily and should be intact in adolescents.

Objectives: To determine the possible alteration of auditory closure according to central auditory processing tests and the psycholinguistic skills in adolescents and; to analyze the relation between the academic performance with central auditory processing tests and psycholinguistic abilities.

Methods: A descriptive and transversal study was carried out.

Tinnitus, Medial Olivocochlear System, and Music Exposure in Adolescents.

Introduction: The most common cause of tinnitus is the exposure to noise; in the case of adolescents, music is the main sound source they are exposed to. Currently, one of the hypotheses about the genesis of tinnitus is related to the deterioration in the functioning of the medial olivocochlear system (MOCS).

Aim: The aim of this study was to determine the presence or absence of tinnitus in adolescents with normal hearing and to relate it to: (a) the functioning of the MOCS, by the contralateral suppression of the transient evoked otoacoustic emissions (TEOAEs) and (b) the musical general exposure (MGE).
