Methods for computer assisted prediction of acoustics is very important to research in the field of room acoustics, and for development and design of new performance spaces. Computational capacity in computers has increased since Krokstad et al started out in the 1960’s, but so have our demands. This field has over the past century grown to become the Queen of room acoustics. Reflector array and orchestra canopy design Performers perception of own voice or instrument It is a common experience that people find recordings of their own voice strange and weak, missing the low frequency emphasis typically perceived by one self. Stage acoustics, support and mutual hearing in ensemble There are still many topics to investigate in this field. Some say it has only just begun. Orchestra canopies are often called for, but can they always be justified? Diffusivity—its significance to perceived sound quality The significance of diffusivity to perceived sound quality is widely recognized, but there seems to be even more to reveal. Paper was presented at BNAM 2006. The opposites of diffusivity are echoes, modes and false localizations or image shifts (link to 3MB pdf-document) Directivity of musical instruments - how to deal with it? Directivity of musical instruments and its significance to sound quality as perceived by the audience has been investigated since late 60-s.

They are among the prominent sound effects that are important to predict during design. What are the significant acoustic properties of a good rehearsal room? Speech intelligibility— which acoustical and architectural factors make a difference, and how can it be predicted and measured? |
