“…Objective parameters related to these attributes were found here to correlate with the subjective impact. According to previous international surveys of concert halls, 11,12 classical shoebox-shape halls, such as Vienna Musikverein, Berlin Konzerthaus, or Amsterdam Concertbegouw, have been generally considered to create the most preferred acoustic impression. Earlier studies have connected the acoustical success to an enveloping, strong, and resonant sound.…”

“…[7][8][9] Certain concert halls have attained a venerable public reputation, 10 and the reasons explaining the subjective preference for room acoustic conditions have attracted continuous interest. 9,[11][12][13] Although preferences have been found to correlate with mixtures of desired perceptual attributes, measured acoustical properties have not succeeded in resolving the difference between acceptable and truly excellent concert hall acoustics. We present evidence that the music in outstanding halls evokes increased emotional impact and pleasurable sensations-elemental factors that may be essential for a profound overall concert experience.…”

An audience's auditory experience during a thrilling and emotive live symphony concert is an intertwined combination of the music and the acoustic response of the concert hall. Music in itself is known to elicit emotional pleasure, and at best, listening to music may evoke concrete psychophysiological responses. Certain concert halls have gained a reputation for superior acoustics, but despite the continuous research by a multitude of objective and subjective studies on room acoustics, the fundamental reason for the appreciation of some concert halls remains elusive. This study demonstrates that room acoustic effects contribute to the overall emotional experience of a musical performance. In two listening tests, the subjects listen to identical orchestra performances rendered in the acoustics of several concert halls. The emotional excitation during listening is measured in the first experiment, and in the second test, the subjects assess the experienced subjective impact by paired comparisons. The results showed that the sound of some traditional rectangular halls provides greater psychophysiological responses and subjective impact. These findings provide a quintessential explanation for these halls' success and reveal the overall significance of room acoustics for emotional experience in music performance.

“…Previous studies have investigated the impact of surface scattering on the acoustic quality of performance buildings using three methods: subjective surveys, computer simulations, and scale-model tests. By assigning values to the concavity or convexity of the walls and ceilings of concert halls, Haan [5] conducted a subjective survey, concluding that the scattering state of walls and ceilings was highly correlated (or to be more specific, positively correlated) with concert-hall evaluation scores. However, high acoustic quality was not analyzed in detail in these evaluations.…”

In terms of the overall diffusion sound field, the inherent diffusion state of the space and the scattering coefficient of indoor surfaces work jointly to diffuse sound energy. This study has investigated the impact of surface scattering on reverberation time in differently shaped spaces. First, 10 spaces with the same volume but different shapes were calculated using a computer simulation; Next, two typical spaces were selected to calculate 10 states, in which the volume was multiplied. The calculations results show that the impact of surface scattering on reverberation time in differently shaped spaces follows three laws: in a group of spaces with the same variation pattern, T20 varies with scattering coefficients at a similar rate. In a group of spaces with different variation patterns, there is a difference of more than 5% in the change rate of T20 with scattering coefficients; in imperfect diffusion spaces, decay curves vary in accordance with scattering coefficients. If the scattering coefficients are the same, T20 varies with spatial shapes; when the volume of rectangular spaces and trapezoidal space ranges from 3000 to 30,000 m3, the change rate of T20 is less than 5%. In the present study, spaces were classified by the position combination of shape surfaces. On this basis, we proposed and then graded the concept of “morphology diffusivity”.

“…The effects of acoustic scattering on the prevention of acoustic glare and echoes, and on the enhancement of the acoustical quality of performance spaces of different sizes and shapes, have been pointed out in the studies conducted during the last few decades [1][2][3] . The importance of acoustic scattering in the modeling of sound fields in enclosed spaces has also been the main topic of several publications [4][5][6][7][8][9] .…”

The Influence of a Volume Scale-Factor on Scattering Coefficient Effects in Room Acoustics

Acoustic scattering has become an important input parameter in geometric models, and in research concerning the enhancement of auralized sound. This contribution deals with a comparison of four scaled prediction models of the same concert hall and a study of the scattering coefficient prominence in simulations, while the size of the concert hall doubled. The hall is fan shaped with an aspect ratios of about 4.5:2.8:1 and has typical auditorium features, such as a stage and a raked audience area. The influence of a volume scale-factor on the scattered sound effects on the prediction of the objective room acoustic parameters, that are, EDT, C 80 , D 50 , LF 80 and G, has been investigated. Five different alternatives, in which scattering coefficient percentage values of 10, 30, 50, 70, and 90%, respectively, were applied separately and combined to the interior surfaces of the ceiling, side and rear walls, have been simulated. An analysis has been performed studying the results of the objective room acoustical parameters predicted, through simulations carried out with two kinds of software: Odeon 11.00 and CATT-Acoustic v 8.0.
