Confronting ISO: On the Use of the dBA Symbol for A-Weighted Sound Levels

The International Organization for Standardization (ISO) recommends the symbol dB for all instances where decibel units are used, particularly in the cases of quantities such as the A-weighted and C-weighted sound pressure levels, ruling out the symbols dBA y dBC. In this paper several arguments...

In this paper several arguments are put forward as to why such recommendation is mistaken and should be revised, taking into account that the dB prefix is used in the symbols of many substantially different units as well as the fact that there are examples of situations where the criterion hereby proposed is accepted. La Organización Internacional de Normalización (ISO) recomienda el símbolo dB para todas las instancias de uso de unidades de decibel, en particular en los casos de cantidades como el nivel de presión sonora con ponderación A y C, censurando los símbolos dBA y dBC. En este trabajo se argumenta por qué ello es un error atendiendo al hecho de que el prefijo dB se utiliza en los símbolos de muchas unidades sustancialmente diferentes y a la existencia de ejemplos de situaciones donde se sigue un criterio similar al propuesto. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/216 10.37537/rev.elektron.9.2.216.2025 eng FIUBA https://elektron.fi.uba.ar/elektron/article/view/216/392 https://elektron.fi.uba.ar/elektron/article/view/216/402 Derechos de autor 2025 Federico Miyara Elektron Journal; Vol. 9 No. 2 (2025); 37-41 Revista Elektron; Vol. 9 Núm. 2 (2025); 37-41 Revista Elektron; v. 9 n. 2 (2025); 37-41 2525-0159 2525-0159 ISO units decibel A ISO unidades decibel A Confronting ISO: On the Use of the dBA Symbol for A-Weighted Sound Levels Enfrentando a la ISO: Sobre el uso del símbolo dBA para los niveles sonoros con ponderación A info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=216_oai
