This document presents a synthesis of the held research on the sound reduction index in windows both with and without trickle vents, with small openings for permanent natural ventilation between the frame and the windowpane. These devices are invisible to the users and do not affect the natural light from the window. In the case of windows with shu...
Face masks are an element of health safety. When placed in front of the mouth of an acoustic emitter, sound waves experience, in their propagation, an additional resistance to that of the air. This may decrease the intelligibility of some frequencies, as they reach the ears of the receivers with less energy. This study seeks to assess, both objecti...
Sensory-driven illusions, such as those produced by sounds in combination with tactile and/or proprioceptive cues, can significantly alter people's body perceptions. The footsteps illusion exemplifies this phenomenon. However, individual differences in the effects have been observed, which may be attributed to body ideals or symptomatology of eatin...
C80 is an acoustic parameter that evaluates the influence of the room on the perception of musical clarity. Numerous studies have been carried out to determine its just noticeable difference (JND).

Una alta porosidad es fundamental para facilitar la absorción del sonido. Si bien existen métodos para la obtención de la porosidad, los métodos por saturación con líquidos suelen subestimar la porosidad abierta al no saturar los poros más pequeños y los métodos de picnometría requieren infraestructura de alto costo. En este trabajo se pre...
Resumen
En las últimas décadas se han realizado grandes esfuerzos para encontrar magnitudes globales del aislamiento acústico (SNQs) que muestren una alta correlación con la sensación subjetiva. Pese a estos esfuerzos, no existe consenso aún hoy en día. Para dar respuesta a este hecho se han realizado numerosos listening tests, en los que se ha inv...
The use of acoustic virtual reality technologies makes it possible to restore the sound of historical sound spaces as these were in their original state. The process of creating acoustic models that allow this reconstruction consists usually of two phases. In the first phase, an acoustic model representing the current situation of the building is m...
The measurement of the sound absorption coefficient is clearly described in the ISO 10534 series of standards as well as in the ISO 354:2003 standard. However, the methods described in these standards are intended for laboratory testing under certain controlled conditions. There are situations where measurements have to be carried out in situ, as t...
Single-Number Quantities (SNQs) are used to evaluate the performance of sound insulation elements through a global and quantitative value that takes into account the contribution of all frequency bands. In recent years, several studies have been carried out to investigate how representative these magnitudes are of the subjective perception of sound...
The objective of a virtual acoustic model is to faithfully reproduce the sound of the acoustic environment that is represented in the model. Therefore, the model is often calibrated by in situ acoustic measurements. The usual procedure to calibrate the model is to compare the values of the room acoustical parameters obtained by measurements with th...
Rolling shutters or blinds are elements placed outside the window. They aim to protect the interior of dwellings from the direct exposure to sunlight. Even though they are not usual in some countries, they are commonly used in Mediterranean countries due to longer exposure to daylight. Acoustic insulation of window elements might be modified due to...
