Are Your Video Conference Room Acoustics HD-Compatible?

Are Your Video Conference Room Acoustics HD-Compatible?

There are many market factors driving the growth of video conferencing, and manufacturers like Polycom and ClearOne have responded with better technology. These modern video conference systems offer bigger displays, higher resolution video, high definition audio quality, integration with mobile apps, and so on. However, if this advanced technology is installed in a poorly designed conference room, the results can be disappointing. A good conference room design and system installation takes into many factors, including lighting, background color and patterns, camera and video display locations, microphone and loudspeaker type and placement, background noise, and room acoustics. This post will focus on ways that the room design can enhance or reduce the audio quality of the system. A follow-up post will provide more detail on good room design principles to get the best audio quality possible out of any videoconferencing system. The advent of HD audio quality Traditional video and teleconferencing systems relied on telephone connections for communication, which inherently limited the audio quality. For example, landline phones are filtered to a narrow range of frequencies that are most important to speech intelligibility. As a result, voices can still be understood, but they don’t sound as natural as they would if you were in the same room with the person. Compare these two audio files to see if you can hear the difference in quality: unfiltered audio  audio with telephone filter As we move away from landlines to cell phones and VOIP systems, there are other ways that audio quality can be compromised. High quality digital audio requires a lot of data and causes network congestion. Phone systems try to...
Avoid CrossFit Noise Complaints

Avoid CrossFit Noise Complaints

CrossFit Gym Noise High Impact workouts – such as CrossFit and other high intensity Boot Camp style strength and conditioning programs – are gaining in popularity throughout the country. Neighborhood gyms, which were once quiet retreats where clients worked out independently on treadmills with their headphones on, are now social hubs overflowing with people, activity, and loud music. These modern gyms have become one of the biggest sources of noise complaints we see in retail and multifamily buildings. Vibration from dropping weights, medicine balls bouncing off of walls, and the bass rumble of the thumping music can travel into adjoining spaces, even from stand-alone facilities. Shouts, clangs and extremely loud rock and hip hop music are the norm. In multi-family buildings, the noise and vibrations can travel long distances and be heard (and sometimes felt) many floors away. While these workouts are intended to push the limits of the human body, they are also pushing neighbors to the limits of their sanity. We work with gym owners, fitness centers, property managers and tenants, to reduce noise intrusion from gyms, whether it is new construction or an existing facility. Solving Exercise Noise Wave Engineering will evaluate your new project and can perform extensive testing and evaluation of existing conditions to give you a realistic picture of the solution, and how much improvement is possible. Sound Isolation can be improved to counteract the effects of loud music and amplified instruction on neighboring tenants. We can evaluate walls, floors and ceilings to determine where money is best spent to reduce sound and vibration. Don’t be a weakling – let Wave Engineering help...
Happy Birthday Wave Engineering!

Happy Birthday Wave Engineering!

Wave Engineering took some pretty big steps in our third year. We added two experienced consultants in Andrew Kowalyshyn and Ben Seep. Both bring years of acoustical knowledge and a variety of expertise to the firm. A bigger staff required a bigger office, so we moved into our current Littleton location. We continue to work on many interesting and challenging projects and look forward to seeing what the next year brings. Thanks for all of the...

Low-Frequency Acoustic Fire Extinguisher!

George Mason engineering students Viet Tran and Seth Robertson developed an acoustic fire extinguisher using low frequency (bass) sounds, and have released a demonstration video of their prototype extinguisher in use. From CNN.com: Boom out da fi-ya! Bass out da flames! Firefighters may be snuffing blazes with deep-toned sound, if a new device invented by two engineering students in Fairfax, Virginia, catches on. Viet Tran and Seth Robertson’s new fire extinguisher looks a little like a conventional one, but instead of a compressed air tank spewing out chemicals, theirs has a loudspeaker the size of subwoofer drumming out sound waves. It’s not much to listen to, just a low hum, but when pointed at flames, it makes them vanish. In a way, it’s like blowing the fire out, because sound waves are basically multiple, regular blasts of air. Click here to visit the original...
