摘要
The dynamics between sound decay and soundscape determines the acoustical worship heritage in a worship space that needs to be conserved along interventions in time.The soundscape of Schmerzhaften Mutter Gottes,Vilgertshofen was measured by derived Acoustical Worship Parameters:Sacred Awe(SAWE),Sacred Intelligibility(SINT),and Sacred Silence(SSIL)for“TOCCATA”of Johann Sebastian Bach rendered on the pipe organ.The sound energy decay in the church,conducted from two sources:choir loft and altar,generated acoustical monaural measures(RT60,EDT,D50,C80,TS,STI,Leq)in accordance with ISO-3382.The Reverberation Time(RT60)spectral analysis and Loudness(Leq)positional analysis showed the church to be more reverberant for the impulse from the altar location on the sanctuary floor and optimally loud for the impulse from the pipe-organ location on the choir-loft.SAWE,SINT and SSIL significantly related with subjective acoustical quality of Balance(SAQBAL)and Loudness(Leq)(p≤0.05).SAQBAL showed positive correlation with rapid speech transmission index(RASTI)(p=0.18).
