Why Your Conference Room Technology May Soon Be Obsolete
You can’t get away from the digital age. It seems like digital technology is everywhere. As Audio-Video designers, the march towards all things digital is having an impact on display technologies as well. Meanwhile, flying under the radar, there is a subtle shift happening in how the average person shows information from a computer onto a projector or display. (more)
If It Sounds Like Noise to You, It May Be “Esion”
Fundamentally, sound is “that which we hear”. What we hear at any given time can greatly influence us. We use sound to communicate, to express warning, fear, pleasure and excitement. Some sounds can relax us and help us fall asleep, while other sounds can distract us and make it more difficult to perform simple tasks. Different sounds can be soothing and pleasing or annoying and irritating. Accordingly, determining “What is sound?” and “What is noise?” can become a highly subjective task. As engineers and scientists, it’s our job to generate generalized models that have a high level of correlation to humans (or to specific populations). (more)
When One Size Does Not Fit All | Diffuser Sound Levels
On a recent trip to India, I discovered a cute clothing sizing term called “free size” which is equivalent to “one size fits all”. Free size clothing must be a manufacturer’s delight since production and distribution are greatly simplified. Adjustments to the size of the garment are typically made through waist ties of various designs and if needed, permanent alterations.
In the A/E/C industry, diffuser, grille and register (air device) manufacturers have chosen the free size philosophy when it comes to providing sound data. (more)
How LEED V3 Changes Everything

This information is especially important if you are working on a LEED project or if you are a LEED Accredited Professional. Here are some of the initial updates at a glance: (more)
How Green Design Can Save You Some Green $$$
It seems like every project that comes across my desk has a stated goal of attaining some level of LEED Certification (LEED Silver, Gold, Platinum, whatever). We’re talking K-12 schools, universities, healthcare facilities, churches – they’re all “going green.” But how much does all this stuff cost? And can green design really save you some green $$$?

HD Videoconferencing and The 21st Century Patient
Whether you watch HD from Blu-ray disks or over-the-air HD broadcasts, the clarity of the image is stunning. With widespread availability of professional HD imaging devices, monitors, and support gear, the clarity we’re seeing at home is now making its mark on the workplace and on the healthcare setting. A new phenomenon in smaller medical facilities is the use of HD videoconferencing with offsite offices and specialists. A properly designed system allows medical professionals to instantly collaborate with offsite experts, delivering an accurate and timely diagnosis while reducing the costs of time and travel for the patient. This stuff really works, and it is fast becoming a new benchmark of healthcare facility design. (more)

- Acoustical Case Studies from new, “acoustically green” hospitals
- After the Storm – future implications for architects, engineers, planners, building owners, and medical professionals
Where will future trends in acoustics, noise and vibration take the healthcare market? How will healthcare patients be the ultimate winners? Find out now! Download The Perfect Storm: Why Acoustics Suddenly Matter in Healthcare Design.
Elbows vs. Sound Attenuators: Interchangeable?
It is common belief that a series of elbows near an air handling unit (AHU) can accomplish the same insertion loss as a manufactured duct sound attenuator. It’s true that elbows are less expensive than sound attenuators, but what acoustical performance is really achieved with this “low cost” substitution?
Let’s compare the two designs. Using the tables presented in the 2007 ASHRAE Handbook – HVAC Applications, for any type of elbow (round, rectangular, acoustically lined or not), the width of an elbow (in the plane that it turns) must equal or exceed 30 inches to get ANY insertion loss at 63 Hz. A 30 inch wide elbow provides only 1 dB of insertion loss (IL) at 125 Hz . These two frequencies are typically of concern when reducing sound from AHUs.
Acoustics, Patient Care, and The Healing Environment
The healthcare industry is booming and your healthcare costs are rising, so what do you get out of it? Well, besides higher monthly premiums and insurance costs, you do get one thing: choice. You have the freedom to choose between everything from primary care providers to hospitals to outpatient clinics to rehabilitation centers. And this choice is driving up the competition between healthcare providers causing them to place a higher priority on, well – you – getting you and keeping you as a loyal customer, uhm… I mean patient.

NICU Noise Control Research for Hospitals
The medical community and design community journals contain many papers discussing noise levels in neonatal intensive care units (NICU’s), how loud they should be and how to achieve those levels. Unfortunately, the recommended noise levels vary and the design recommendations contain few specifics that have been evaluated by qualified acoustical design professionals. Here is a sample of some of the recommended criteria. (more)
It’s time for another semester, and I tell my architecture students that if there’s one thing they learn in my acoustics class, it’s that porous absorbers do not block sound. A porous sound absorber, by definition, has many tiny interconnected voids that sound travels through. Fiberglass and open cell foam are examples. The sound wave loses its energy through friction between the air particles and the fibers/void walls of the material it is passing through.

4 Basic Concepts for Corporate Board Room Video Conferencing Systems
It’s January, and that means new budgets for companies that operate on the calendar year. If this year is anything like the last, it means we will be receiving calls from companies inquiring about corporate board room video conferencing systems. As AV Consultants, one of the most common questions we get asked is, “What do other companies have for AV equipment in their Boardrooms?” And the follow up question is always, “Should we be looking at a video conferencing solution?” It seems, in the business world, everyone is concerned that if their technology is behind the curve, then they won’t be as competitive. And we are all concerned about how these new technologies affect our bottom line. But believe it or not, video conferencing may be a viable and cost-saving solution for almost any company that seeks to enhance its communications. (more)
LEED for Healthcare to be Adopted in 2009
The LEED Green Building Rating SystemTM is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. LEED was created by the U.S. Green Building Council to define “green building” through a common standard, and to promote integrated, whole-building design practices. There are several categories of LEED building certification programs including: LEED for New Construction, LEED for Existing Buildings, LEED for Schools, and LEED for Retail, just to name a few. And as of last week, the U.S.G.B.C. announced plans to adopt a new LEED category in 2009: Healthcare. (more)
What’s Shakin’ in Healthcare
Unfortunately, sometimes it’s the walls, the floor, or the ceiling. It seems like every hospital I’ve visited in the last five years is under construction, renovating their current space or planning for large additions. With all the changes, it’s easy to forget about the “unseen” aspects of the design, such as Mechanical Noise and Vibration Control.
A common problem is loud mechanical units going in over operating suites. Vibration and noise from the mechanical units can cause problems with the medical equipment inside the suite. Too much noise and vibration can ultimately compromise the accuracy of the equipment. This can lead to misinterpretation of medical data and serious health issues. Operating suites are also very active places with lots of health caregivers interacting with each other. Excessive noise levels in the operating room can cause communication issues at a critical moment in time. (more)
