Mixing noise pollution with an intimate auditorium setting is almost always a bad idea, and as the song says, “You gotta keep em’ separated.” There’s nothing like untimely noise pollution to ruin the flow of a good theatrical performance or vocal recital. For our purposes today, we will define “noise pollution” as any unwanted sound impeding at an unwanted time. When you’re engineering acoustical solutions for an auditorium, the importance of noise isolation is paramount, and it’s the only way to really keep the “bad sound” out. Noise pollution can hinder speech intelligibility and greatly reduce the ability for an audience to hear and understand what is being said. In auditoriums, noise pollution can come from a wide array of culprits from within or without the facility. (more)
The challenge with contemporary church architecture is that the term “contemporary” means a lot of different things to a lot of different people. For some, it means a praise band and a projector. For others, it means the service is full of drama, dance, video, interactive preaching, and more. With all the different styles, a lot of contemporary churches feel stuck in the middle with facilities that are in between “where it is” and “where it ought to be.” (more)
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)
