Arte Rupestre: Una Perspectiva Desde Los Paisajes Sonoros

Abstract

[eng]: Intangible cultural heritage is an emerging research line directly relate to the study of soundscapes. Through its methods it is possible to apply a perceptual, subjective approach, to find parameters and relationships that may not have been previously considered in an archaeological context. In this sense, this communication focuses on the archaeoacoustic studies undertaken in the framework of the interdisciplinary ERC Artsoundscapes project (ref. 787842). The project aims to investigate the relationship between the presence of rock art and the acoustics of the shelters and landscapes where they are found. The case study presented in this work is based on the analysis of third order ambisonic recordings and impulse responses obtained in open-air rock art shelters located in the areas of Kamberg and Giant’s Castle (South Africa). In addition to traditional room acoustics measurements, a calculation of psychoacoustic parameters was also performed according to the ISO-12913 standard. and include loudness, sharpness, roughness and fluctuation strength. In this article, we explore the methodology and levelcalibration procedure. The results obtained point to high values of sharpness due to the presence of water and good spatiality, reproducibility and scalability allowing reproduction in audio systems with up to 16 channels used in laboratory environments.

[spa] El patrimonio cultural inmaterial es un tema de creciente interés académico que está teniendo un efecto directo en el estudio del paisaje sonoro. Usando un enfoque perceptual y subjetivo, es posible encontrar parámetros y relaciones que pueden no haber sido consideradas previamente en un contexto arqueológico. La investigación que sustenta esta comunicación forma parte de la disciplina de la arqueoacústica y se ha llevado a cabo en el marco del proyecto interdisciplinar ERC Artsoundscapes (ref. 787842), cuyo objetivo es estudiar la relación entre emplazamientos de arte rupestre y la acústica de sus paisajes. Concretamente, este trabajo se basa en grabaciones ambisónicas de tercer orden junto con respuestas de impulso registradas recientemente en abrigos naturales en el área de Kamberg y Giant’s Castle (Sudáfrica). Además de las mediciones de acústica de salas tradicionales, se realiza un cálculo de parámetros psicoacústicos siguiendo el estándar ISO 12913, incluyendo sonoridad, nitidez, aspereza y fuerza de fluctuación. En esta comunicación, se explora la metodología y el procedimiento de calibración de nivel. Los resultados apuntan a unos valores altos de nitidez por la presencia de agua y a una buena espacialidad, reproducibilidad y escalabilidad al poder emplearse sistemas de hasta 16 canales en laboratorios.
