Design criteria for acoustical excellence of auditoriums

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Electrical engineering and nontechnical design variables of multiple inductive loop systems for auditoriums.

This research analyzed both engineering and nontechnical issues involved in the use of Induction Loop Amplification (ILA) devices in auditoriums or large gathering places for hard-of-hearing individuals. A variety of parameters need to be taken into account to determine an optimal shape/configuration for the ILA device. In many cases, an optimal configuration is different from those proposed fo...

Computer Simulation Techniques for Acoustical Design of Rooms

After decades of development room acoustical computer models have matured. Hybrid methods combine the best features from image source models and ray tracing methods and have lead to significantly reduced calculation times. Due to the wave nature of sound it has been necessary to simulate scattering effects in the models. Today's room acoustical computer models have several advantages compared t...
