Direct-To-Reverberant Ratio Threshold for Localization in Concert Halls

Abstract: Direct-to-reverberant ratio threshold for localization was studied with anechoic orchestra instrument recordings in auralized concert halls. Excerpts of anechoic music were convolved with spatial impulse responses and reproduced with a multichannel loudspeaker system in anechoic chamber. Participants adjusted direct sound level in order to explore the transition range of localizability, with separate tasks for precise and imprecise localization. Halls with contrasting acoustics, and excerpts with pairs of inst… Show more

“…About 80 of the interviews were used to acoustically rank order 58 halls and the results were published in 2003. 2 In 2013, Skålevik published the results of a recent online questionnaire that ranked 77 concert halls according to their acoustical quality. In Table 1 the results of the two studies are combined to obtain a choice of the top ten concert halls.…”

“…Subsequently, Barron (1988) assessed the relative importance of various aspects of room sound administration of ques-tionnaires to a group of expert field listeners in British rooms (Barron, 1971;Barron, 1988). Hidaka and Beranek (2000) have produced many publications (Beranek, 2003;Beranek, 2004;Beranek, 2008;Hidaka and Beranek, 2000) on acoustic measurements in many well-known evaluation rooms from Beranek's interviews with conductors and other knowledgeable listeners. Although there are general findings from these more comprehensive research efforts, there are also many differences in which parameters are the most important and relative importance of each parameter.…”

“…necessidades de acústica, é importante lembrar que a configuração ideal para uma sala de concertos seria a configuração da caixa de sapatos, conforme recomendaBeranek (2003), em função dos requisitos de tempo de reverberação. Essas proporções sugeridas pelos engenheiros da época terminavam na altura das colunas (Figura 22a), no entanto, o compromisso era restaurar o prédio por completo, ou seja, até sua altura integral.…”

“…Se o tempo de decaimento for muito maior do que o intervalo entre as palavras, quando a pessoa estiver falando a segunda palavra, ainda existirá muita energia sonora no local reverberando a primeira palavra, isso pode gerar um certo mascaramento e atrapalhar a compreensão da fala. Por outro lado, em um concerto onde as notas musicais tocadas possuem duração maior, este mesmo tempo de reverberação não vai prejudicar, e, pode ainda, contribuir para enriquecer o timbre final da música e reforçar o som.Outra situação possível é o da música percussiva, situação em que temos muitas notas musicais sendo tocadas em um curto intervalo de tempo e que vai exigir outros valores de reverberação, geralmente mais baixos.Um dos primeiros estudos de grande repercussão que buscou entender a conexão entre as melhores salas de concerto e os seus respectivos tempos de reverberação foi conduzido porBeranek (2003). Nesta pesquisa, 58 salas foram avaliadas através de questionários e medidos diversos parâmetros acústicos.…”
