Abstract:
Low frequency prediction in large and medium-size venues has become a standard in the audio industry. However, acoustic modeling of small rooms has not yet evolved into a widely accepted concept mainly because of the unavailability of one accurate tool set. The workshop will explore currently available software-based approaches and real world applications to low frequency prediction as well as present various means of low frequency treatments. Specific studio examples will illustrate comparisons of these approaches and their success in the field. The workshop will also explore the limitations of current LF design modeling, and in specific the underlying mathematical and numerical algorithms, one of them being ray tracing, which is only valid in frequency ranges where lengths are small compared to the characteristic dimensions of the room, another one being FEM/BEM (Finite Element / Boundary Element Methods) that can be employed to study static pressure distribution in three dimensional spaces. The common dividing line is often identified with the so-called Schroeder frequency. The workshop will review these theoretical prediction limits as well as hope to create a dialogue concerning future prediction, design and remediation techniques.
