“…Reflected or scattered sound occurs in much more limited extent than in enclosures, which causes that its spaciousness is very limited (in case of classic configurations of electro-acoustic installations). For this reason the most important and preferred acoustic parameter determined for sound system in an open area was the sound pressure level (SPL), the other parameters are determined much more seldom [2,3].…”

The paper presents an original method for sound reinforcement in open areas. The method enabled both a regular sound reinforcement and the required spatial impressions of sound to be achieved in the area used for the study. The inverse image source method was used for the disposition of sound sources in order to find the inverse problem solution for determining the configuration of additional sound sources. Simulations demonstrated the improvement of sound impressions in the area in question and the simulations results were verified experimentally. The intended result of the proposed method was the increase of the lateral energy fraction and lateral energy fraction coefficient parameter values by 6 and 8 points, respectively, for the simulation by 5 and 7 points for the experiment. It should be stated that, in both the simulation and the experiment, eligible values for the acoustic parameters were obtained after using the sound system with additional sound sources, the speech intelligibility value parameters remain at an excellent level. In conclusion, it may be claimed that the proposed sound reinforcement system makes the creation of the intended spatial sound impressions in an open area possible.

“…3). In both closed and open models the lowest values are a result of air absorption at high frequencies (8)(9)(10)(11)(12)(13)(14)(15)(16). When comparing the closed and open models in terms of Just Noticeable Differences (JNDs), the mean value is 5.47JNDs, indicating significant drops in the reverberation time as a consequence of the removal of glass and wooden shutters from the windows.…”

“…Several research projects have focused on aspects of the acoustics of street spaces, such as sound propagation in connection to urban noise [4][5][6][7], speech intelligibility [7], weather conditions [7], modelling techniques [5,8] and the impact of acoustics on modern music performances [9,10]. To the author's knowledge no existing studies have focused on investigating the acoustics of street spaces from past centuries through acoustic modelling, thus the present paper is of relevance to future studies on the topic as well as all studies dealing with the acoustics of heritage sites that are not fully preserved and of which we have limited information.…”

“…Thomas et al [36] also investigated the acoustics of urban squares, in particular those used for open-air rock concerts by studying fivesquares in Belgium. Acoustic measurements were carried out employing a12-second exponential sine sweep and the amplification system of the site wasu sed to play the signal.…”

The present paper provides an insight into the acoustic characteristics of one of the spaces used for the performance of the York Mystery Plays:S tonegate, as treet in central Yo rk (UK).A ne xperiment conducted in a controlled environment with the aim of determining the optimal method for acoustic measurements on this site is first presented. The methods tested were the Exponential Sine Sweep (ESS)m ethod with the application of time averaging of eight 15-second exponential sine sweeps and the ESS method with a9 0-second sine sweep. Results demonstrate the greater robustness under the test conditions of the ESS method when used with as ine sweep of 90 seconds in length. Results from measurements at Stonegate using this method are then discussed, demonstrating that the space has appropriate reverberation time and clarity values to ensure speech intelligibility butwould prove less satisfactory for the performance of the plainchant items that were part of the plays. Results also indicate that Stonegate presents lowlevels of spaciousness and high levels of listener envelopment at most of the receiverpositions studied.
