These
are the first two articles written by Art about room acoustics
and corner bass traps. The first paper introduces the TubeTrap,
shows how it is designed and how it is used in rooms. The
second paper takes a look at how room modes are managed
by corner bass traps.
These next two
papers were written in response to the difficulty in accounting
for the satisfaction from TubeTrap use when doing traditional,
steady state room mode analysis, pink noise and tone sweep
evaluation of room acoustics. Articulation accounted for
the dynamic aspects of room acoustics. The first paper covers
the details of MTF testing and the second paper looks at
MTF as a global concept in performance spaces.
The next two
papers are about acoustic spaces for recording. TubeTraps
led recording engineers to discover that lots of very early
reflections produce a better, more manageable sound than
the traditional, reflection-free, dry studio recording.
The first paper introduces the concept of a sampling room,
highly reflective with a fast RT60. The second paper introduces
the free standing QSF version of Haas Saturated recording
approaches the same subject from a generalized overview.
This last AES
paper by Mr. Noxon addresses the hot field of acoustic diffusion.
It introduces the concept of coherent and incoherent diffusion,
how to measure it and what each type is good and not good
for.
This AES paper
presents the results of a successful collaboration between
Arthur, the authors who are audio engineers from Croatian
Television and our Italian TubeTrap factory, Acoustica Applicata.

- With the addition of TubeTraps a large music hall with
a long reverb time was successfully converted to a television
production stage.
