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.
