HVAC Noise Is Intruding On My Listening
Being a noise engineer, I’m always on the “listen-out” for cases of poor building acoustics. I find that common offenders are noisy air handling (HVAC) systems. Frequently the public venues are restaurants, hotels and cinemas, and on occasion it’s a location most tragic, a performance space. (more)
Noise Isolation for Hospital Mechanical Rooms
Hospitals and Healthcare Facilities have requirements for large volumes of ventilation and strict control of airflow, and the greater the airflow, the greater the potential for noise. Building mechanical services equipment, fans, pumps, cooling, and heating equipment are all sources of high noise levels. When Acoustics By Design works on a new hospital, we typically expend half of our effort on attenuating building mechanical systems noise. In order to avoid the need for extensive noise and vibration isolating constructions, project designers and engineers should pay careful attention to mechanical room sizes and locations during schematic design. Here are some issues to address early on… (more)
Acoustics for Video Venues & Portable Churches
From mega-churches to small town congregations, the video-venue concept is becoming a staple of church growth. For those not “in the know”, a “video-venue” is a church meeting where parts of the service (typically the sermon or message) are piped in via video signal and projected on a large screen, while other parts of the service (like the music or announcements) are done live. Since the sermon is filmed in the “main sanctuary”, it can be broadcast to different rooms within the same church building (onsite video-venues) or to campuses across town, out of state, and beyond (offsite video-venues). As a devoted church member and as an acoustical consultant, I have experienced many different types of video venues firsthand, and I have found a common thread of acoustical “challenges” they typically face. If you are planning a video-venue or portable church ministry, here are some important items to consider before selecting your new space… (more)
