  • Mastering the Challenges of Perforated Sheet Metal 16|17
    MASTERING THE CHALLENGES OF PERFORATED SHEET METAL 16|17 Perforated sheet metal differs greatly from non-perforated sheet material. It is the perforations that cause particular tension and unevenness in this material when it is being fabricated. However, these negative characteristics must first be eliminated to make the perforated sheet metal suitable for further processing. This is a particular challenge for perforated sheet metal manufacturers, but it can be mastered with the right levelling technology and a bit of experience. Perforated sheet metal is not simply a piece of sheet metal in which holes have been punched arbitrarily. Indeed, the numerous sheet metal manufacturers operating on the market orient themselves on certain standards for perforated sheet metal and the perforation patterns. In the relevant DIN 4185-2 and DIN 24041 standards (DIN refers to the German Institute for Standardization), perforated sheet metal is designated as "perforated metal plate" - the term perforated sheet metal has, however, established itself among manufacturers and users. In the DIN standards, a perforated metal sheet is described as a panel or plate with openings of a certain kind - that is, holes - in a regular pattern. The holes are usually made by punching, but sometimes also by drilling or laser cutting. The holes can have different geometrical forms (round, square, long hole) and sizes. In contrast to the DIN description, the pattern can also be defined individually. Areas of application Perforated metal sheets are products that require the particular attention of the manufacturer or processor during manufacturing and processing. They are used as functional components such as sieves or filters, or to decorate the facade of modern office buildings with their optical design.

  • The Art of Illusion and Distraction in Integrating Loudspeakers Within Themed Environments Prepared for the 61St Annual USITT Conference, March 8-12, 2021 Version 2
    The Art of Illusion and Distraction in Integrating Loudspeakers Within Themed Environments Prepared for the 61st Annual USITT Conference, March 8-12, 2021 Version 2 Nathan McWilliams Senior Audiovisual Consultant, Arup [email protected] https://www.arup.com/ Lisa Sun Principal Show Set Designer, Resolution Design Inc, Production Design Consultant, Meow Wolf Denver https://www.resolutiondesigninc.com/ Shawn Tuohey Owner/Principal Show Set Designer, 2E Scenic Design Studio [email protected] (321) 230-5639 Chris Hill Senior Creative Director of Themed Portfolio, Adena Corporation [email protected] http://adenacorporation.com/ 1. Abstract: Loudspeakers can be cumbersome objects to integrate into themed environments, and a sound designer’s desire to keep sound images on stage or aligned with a particular aural aesthetic can conflict with a scenic designer’s drive to shape the visual narrative. This paper explores techniques used to craft illusions for hiding loudspeakers in a wide variety of themed environments, but with a particular focus on methods for executing hides in diverse materials, diverting audience attention away from loudspeakers, balancing tradeoffs like cost or longevity, and team consensus building to ensure that themed speaker grilles are seamlessly integrated and sounding great. pg. 1 2. Scope and Purpose: This document is not a scientific research document. While some of this experience was gathered from best practices informed by scientific method, this paper does not explore scientific measurement. This is a document intended to share our experience designing and building immersive environments. We have a collective combined working experience of more than 60 years working for Walt Disney Imagineering, Universal Studios, Adena Corporation, Meow Wolf, Arup, and other world class design studios.
