Abstract
The temporal and spatial factors in relation to subjective evaluation are characterized against changes in the listening conditions inside a box and procedures for improvement and design methods for boxes are proposed. The maximum listening level (LL) in the boxes was observed at the front of the box and the maximum range of LL values for each box was found to be 5dB. The subsequent reverberation time lengthens for boxes closer to the stage due to the stage house with its huge volume and a peak is observed at 1kHz. As the contribution of multiple reflections relatively increases for a receiver deeper in the box, the IACC in such positions decreases in comparison with that seen at the front of the box.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
