O presente trabalho visa o estudo de sete espaços destinados à produção sonora e musical, com diferentes níveis de especialização, destinados à produção sonora e musical. O objetivo é traçar um perfil objetivo de cada espaço, baseada em parâmetros quantitativos, obtidos através de uma metodologia repetível, para posterior análise individual e comparativa dos espaços. O estudo identifica diferenças quantitativas, que justificam as diferenças na performance acústica de um espaço de tipologia Home Studio de um espaço de utilização profissional. São identificados vários parâmetros que justificam essas diferenças, tais como valores de Bass Ratio, iguais abaixo de 1,38, diferença de energia entre o som direto e primeiras reflexões igual ou superior a -14 dB, valores médios de C50, quando medidos entre as bandas de oitava de 500 Hz e 4000 Hz
iguais ou superiores a 19,98 dB, entre outros. Por fim, é avaliada a viabilidade de converter um espaço doméstico, como um quarto ou uma sala, para as funções de estúdio de produção áudio, com performance similar a um espaço profissional. Tendo os espaços profissionais estudados como referência, conclui-se que é possível a referida conversão ser bem-sucedida, mas apenas em espaços cuja volumetria permita acomodar os recursos de acondicionamento acústicos necessários. No exemplo apresentado, a área útil do espaço diminuiria de 18,05m2 para 13,20 m2 e com o teto a baixar de uma altura de 2,64 m3 para 2,20 m3.
This work aims to study seven different music and audio production spaces, which have different specialization levels between them. The objective is to develop a profile for each space, based on quantitative parameters, obtained through a repeatable methodology, for later analysis and comparison. The study identifies quantitative differences, that justify the differences in acoustic performance between a home studio type space and a professional studio. There are several parameters that justify said differences, such as Bass Ratio values equal or below 1,38, energy differences between the direct sound and first reflections equal or superior to -14 dB, average mean C50 values, measured between the octave bands and 500 Hz and 4000 Hz equal or above 19,98 dB, among others. Lastly, it’s studied the feasibility of converting a domestic space to an audio and music production room, with similar performance to a professional studio. After analysis of the available professional spaces, it is concluded that such task is viable, but only if the space as enough volume, as to accommodate the necessary acoustic treatment. In the given example de useful area of the room would diminish from 18,05m2 to 13,20 m2 and the ceiling height would diminish from 2,64 m3 to 2,20 m3.
