As people begin to head back into their places of worship, the focus on acoustics has again come to the forefront. Many have been streaming services and listening to music in their homes, where they had short reverb times and good acoustic clarity. They are experiencing a stark contrast in the large reverberant churches to which they are returning. By adding acoustic absorption in a space, you can improve clarity and reduce reflections which can fatigue the listeners.
The Sonora® Panels above are helping to break up the reflections coming from the balcony face and the rear balcony wall, improving the clarity of the voices and the music within the space. This helps to create an intimate and comfortable acoustic environment for those in attendance – and makes it feel more like home.
Hey! Here’s another installation of our new ArtDiffusor® Nouveau™. For this install, these four boards were not only stained, but also framed out to enhance the design aesthetic. From different paints and stains, to mounting techniques, there are limitless possibilities for customization to create your own unique and functional sound diffusing arrays.
The current crisis has forced a large portion of the workforce to operate out of their homes. Daily Zoom and Skype meetings have become a ubiquitous part of our lives. For many of us, this shift is only temporary. However, some companies are seeing the benefits of working at home, and are making plans to move employees to permanent remote positions.
I’m sure all of you have been on a conference call in which a team member’s audio is difficult to understand. This could be caused by a microphone or connection issue, but a large number of intelligibility problems are rooted in a room’s acoustics. Let’s take a look at some common acoustic issues in home offices and how they relate to conference call clarity.
Background Noise – Obviously, it’s difficult to understand speech when there is a lot of background noise. It is vital that you isolate yourself from extraneous sound sources as best you can. Some sources (TV, HVAC) are easier to control than others (traffic noise, pets, children etc.). Make sure your office is “closed off” from intruding noise. Remember, sound is a little like water; it will “pour in” through any openings, such as gaps around doors. If possible, install full perimeter seals and door sweeps to improve sound isolation in your office. If you have sound transmitting through a wall, ceiling or floor, you can consider adding a layer of mass loaded vinyl to the assembly in order to help block unwanted air-borne noise. You can then cover the mass loaded vinyl with SoundChannels® like in this blog.
Reverberation – In simple terms, reverberation is the sound energy that remains in a listening environment as a result of lingering reflections. The reverberation time (RT or RT60) quantifies how quickly an impulse sound decays in a space. Reverberation time is dependent upon the volume and surface materials of a given room. Large spaces with hard materials (tile, drywall etc.) have longer reverberation times, while small rooms furnished with “softer” materials (carpet, drapes etc.) sound more much more “dead”. Speaker phone conversations require a very short reverb time, for optimal clarity, somewhere in the .5s range (half of a second). You can reduce reverberation in your home office with the addition of “fluffy” or irregular furnishings, acoustic panels, rugs, curtains and plants.
Flutter Echoes – Flutter echo, which can be heard as an annoying “ringing sound”, is caused by parallel reflective surfaces. In certain critical listing environments, sound diffusers are used to alleviate flutter echo. Flutter echoes can greatly degrade conference call clarity. This phenomenon can occur between two walls or floor-to-ceiling. To control flutter echoes in your office, you should break up any parallel surfaces with furnishings and/or sound absorptive treatment.

Sometimes a simple solution is the best solution. That is the guiding philosophy behind our new Sonora® Corner Bass Trap. Take one 4” thick, 6-7pcf sound absorbing fiberglass panel, back bevel to fit in a corner, front bevel for a nice finished look, throw in a few corner clips for mounting, and done!
The Sonora® Corner Bass Trap was born.
This bass trap lives up to the design aesthetic and functionality of the Geometrix® Quarter Round unit, but at a lower price point with reduced weight for an easy installation. Available in widths of 24” or 18”, standard length is 4’ with custom lengths available.
The Sonora® Corner Bass Trap is a great option for studios, theaters, or any critical listening environment where broadband absorption with enhanced low frequency control is desired.
When Sound & Communications needed some industry perspective on diffusion, they decided to go to the source. Acoustics First has been developing sound diffusers for decades, and has done some of the most comprehensive research on developing testing standards for diffusion and reflected acoustic energy with the ASTM.
Acoustics First’s chief science officer, Jim DeGrandis, covers why diffusion is so much more complex than absorption in the February 2020 edition of Sound & Communications.
Acoustics First would like to remind everyone that it’s the little things that matter…
…remember to wash your hands and stay safe.
