Abstract

© 2020 Elsevier Ltd The sound insulation provided by a certain construction element is usually presented through Single-Number Quantities (SNQs). These SNQs are global values used to summarize the sound insulation that a construction element has as function of the frequency. Although there are standardized SNQs, whose calculation is described in the ISO 717–1 and ASTM E413-16 standards, there is not enough agreement on whether these SNQs are representative of the way humans perceive. The purpose of this research is to assess the degree of correlation between the annoyance perceived by humans and the most relevant existing SNQs for a set of façade insulation elements and urban-type sound samples. Likewise, the purpose is also to evaluate whether certain frequency bands have more influence than others on the perception of annoyance. Furthermore, to propose a reference curve for the calculation of a SNQ that is representative of the annoyance perceived by humans when faced with sounds of an urban nature. To this end, a 2-alternative choice (2-AC) listening test was carried out by 119 participants. In this test, participants had to listen to stimuli in pairs and select the stimulus that was most annoying to them. The stimuli were obtained by filtering different sound samples with the sound insulation of different construction elements. In particular, five sound samples were used for this listening test: four urban-type sound samples as well as pink noise. Also, the sound insulation of six façade insulation elements was used. The results of this listening test were then analyzed using Thurstonian models and the distance measure d’ (d-prime) was obtained for each comparison. Finally, an optimized reference curve for urban-type sounds Lopt-urban was calculated based on the results of the listening test by means of a Sequential Quadratic Programming (SQP) optimization algorithm.

Project objectives

Los objetivos perseguidos en esta aportación son analizar el grado de correlación entre la molestia percibida por humanos y los principales Single-Number Quantities (SNQs) existentes para elementos de aislamiento acústico de fachadas y sonidos urbanos; evaluar la influencia relativa de distintas bandas de frecuencia en la percepción de molestia; proponer una curva de referencia para el cálculo de un SNQ representativo de la molestia percibida ante sonidos urbanos; y validar esta propuesta mediante un test auditivo de elección binaria realizado por 119 participantes, cuyos resultados fueron analizados con modelos thurstonianos y optimizados mediante un algoritmo de Programación Cuadrática Secuencial.

Most relevant results

Los resultados más relevantes de este estudio se centran en la evaluación de la correlación entre la molestia percibida y las cantidades numéricas únicas (SNQ) existentes para elementos de aislamiento acústico de fachadas frente a sonidos urbanos. En primer lugar, se identificó que ciertos rangos de frecuencia tienen una influencia significativamente mayor en la percepción de molestia. En segundo lugar, mediante un test auditivo de elección binaria realizado con 119 participantes, se obtuvieron medidas de discriminación d’ que permitieron cuantificar la molestia percibida. En tercer lugar, se desarrolló una curva de referencia optimizada, Lopt-urban, específica para sonidos urbanos, calculada mediante un algoritmo de optimización SQP. Finalmente, se demostró que esta curva representa de manera más precisa la molestia humana en comparación con las SNQ estándar.
