Sound Insulation in a Hollow Pipe with Subwavelength Thickness
Suppression of the transmission of undesired sound in ducts is a fundamental issue with wide applications in a great variety of scenarios. Yet the conventional ways of duct noise control have to rely on mismatched impedance or viscous dissipation, leading the ducts to have ventilation capability weakened by inserted absorbers or a thick shell to accommodate bulky resonators. Here we present a m...
متن کاملA Robotic Pipe-Asbestos Insulation Removal System
The BOA (Big-On-Asbestos) system is a mobile pipeexternal robotic crawler used to remotely strip and bag asbestos-containing lagging and insulation materials (ACLIM) from various diameter pipes in (primarily) industrial installations. Steam and process lines within the DoE (Department of Energy) weapons complex warrant the use of a remote device due to the high labor costs and high level of rad...
متن کاملSound insulation issues
This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...

The BOA system is a mobile pipe-external robotic crawler used to remotely strip and bag asbestos-containing lagging and insulation materials (ACLIM) from various diameter pipes in (primarily) industrial installations. Steam and process lines within the DOE weapons complex warrant the use of a remote device due to the high labor costs and high level of radioactive contamination, making manual re...
متن کاملPipeTaz: Automated Pipe Asbestos Insulation Removal System
Introduction Airborne asbestos-fiber is an important healthhazard. Asbestos abatement is a significant component of the overall cleanup costs associated with building demolition and renovation. For example, asbestos abatement efforts associated with the DoE’s national weapons’ complex clean-up efforts may amount to $300 million. Abatement costs are primarily driven by the issues related to envi...
