Desenvolvimento e avaliação de ferramentas de simulação acústica imersiva para a promoção de estratégias metacognitivas na preparação da performance musical

Abstract

Research Question/Problem

Musical performance is strongly influenced by the acoustic characteristics of the environment, affecting both auditory perception and musicians’ interpretive decisions. Studies have shown that different acoustic signatures directly impact sound perception (Kato et al., 2015) and lead performers to adjust parameters such as tempo, intensity, and timbre (Ueno et al., 2010). In addition, these variations may influence psychological and emotional aspects, such as performers’ sense of security and control during performance. However, musicians often practice in environments acoustically different from concert halls where performances, auditions, and tours take place, facing a constant challenge of adaptation. In this context, immersive technologies have emerged as promising tools, being widely used across different domains to enhance perceptual and learning experiences (Klico & Muhić, 2022). Such technologies may also contribute to the development of metacognitive processes (Araújo et al., 2024), promoting more conscious and self-regulated approaches to performance preparation.

Objectives

This study aims to evaluate the potential of immersive acoustic simulation—based on real-time convolution reverb and bone conduction headphones (Gozzi & Liuni, 2025)—as a tool to promote metacognitive processes in musical performance preparation across different acoustic contexts.

Method (only for empirical research)

The study adopts an autoethnographic approach articulated with Design-Based Research (DBR) (McKenney & Reeves, 2012), integrating system development with practical application. The system combines bone conduction headphones—which enable simultaneous perception of natural and simulated sound (Stenfelt & Reinfeldt, 2007)—with real-time convolution reverb using binaural impulse responses (Kantorik, 2014). The study was conducted between March and May 2025 and involved reed adjustment and preparation for chamber and orchestral performances. Six experimental conditions were tested (with and without the system; with and without musician earplugs), with systematic documentation in a practice diary.

Main contributions

The use of the system resulted in increased expressiveness (vibrato and rhythmic flexibility), improved precision in the perception of intonation, articulation, and timbre, and enhanced ability to anticipate reed behavior across different acoustic environments. A reduction in physical and mental effort was also observed, along with improved adaptation to the use of earplugs in performance contexts. The system functioned as a mediator of embodied metacognitive processes, integrating auditory perception, bodily action, and musical decision-making.

Implications

Immersive acoustic simulation expands the possibilities for performance preparation by creating practice environments that more closely resemble real concert conditions. Beyond its technological dimension, the system operates as a pedagogical tool that supports self-regulation, bodily awareness, and performer health, opening new perspectives for music performance pedagogy.
