Air-filled balloons are commonly used for party celebrations and, in acoustics, as simple impulsive sources (when burst) to measure sound decay within a room. However, their potential application in other areas, particularly their contribution to sound absorption, has not been extensively investigated, as addressed in this paper. Acoustic measurements were carried out on air-inflated latex...

World Heritage sites often have high reverberation times and low speech intelligibility, which are rarely suitable for their new, modernโday functions. This paper shows how the acoustic refurbishment of two rooms can be achieved while preserving their architectural and historical character.Both rooms are located in the Central building (Building K) of the Budapest University of Technology and...

This study investigates the measurement and evaluation of the Speech Transmission Index (STI) of emergency broadcasting speaker systems in noise barrier tunnels under emergency conditions such as fire incidents. STI measurements were conducted for two types of directional loudspeakers in both a semi-anechoic chamber and an actual noise barrier tunnel. The evaluation was conducted under various...

Room impulse responses (RIRs) are used to characterize rooms, their acoustic behavior and the resulting coloration of the sound. They are widely used in applications for room acoustic design, but also in speech recognition and spatial audio. To describe room impulse responses, well defined features according to ISO 3382 are typically applied, such as e.g. reverberation time, clarity, strength...

La Casa Milร , also known as La Pedrera, is one of the most emblematic works of Antoni Gaudรญ and a landmark of Barcelonaโs architectural heritage. Although its architectural and historical significance has been widely studied, its acoustic behaviour has received little specific attention. This article presents an acoustic experimental study of a historical apartment located within the building....

The Yammat FM radio station, native to Zagreb, Croatia, was recently relocated to a 100-year-old building in the city centre. In 2023, the new premises were fully restored and redesigned by Croatian architects and reputable contractors. The design project aimed to create a distinctive visual and acoustical accessibility of the designed spaces, with the emphasis on two broadcasting studios...

The Porto Metro is a light rail network in Porto, Portugal, in operation since 2002 and currently in expansion. One of the factors that was relevant during its construction was the acoustic quality of the subway stations, particularly reverberation time control. The Portuguese acoustics legislation requires this parameter to be under a maximum value, for all types of passenger transportation...

Schroeder-curves or energy decay curves (EDC) of room impulse responses have a non-positive slope. As a consequence, when quantizing the decay range into level bins, the histogram of probability distribution of EDC levels shows basically the local decay slope or instantaneous decay time for each bin, because heights of bins denote times required to decay in each bin.This simple yet undiscussed...

The paper examines the influence a chosen position and type of the sound source have on measurements of room acoustic parameters and speech intelligibility, as well as the influence of the acoustics of the room itself in terms of reverberance. The measurements were performed in two rooms similar in size but acoustically different, one of them being an acoustically treated multimedia studio...

Comprehensive assessments of room acoustic quality rely on perceptual evaluations. Conducting such evaluations online avoids time-consuming laboratory experiments at the expense of experimental control. This seems hardly feasible, given the technological demands of the accurate reproduction of room auralizations. However, since playback system deficiencies differ between subjects, their...

Room acoustic properties are typically assessed using omnidirectional microphones, from which room impulse responses are derived and used to calculate scalar acoustic parameters. However, spatial measurement techniques are essential for assessing sound fields in spaces equipped with active acoustics systems, since they generate direction-dependent and dynamically changing acoustic responses...
