Summer shifting into fall touches our senses in several ways. Visually, the leaves change colour and the angle of the sunlight changes. We notice the temperature begin to drop and the winds picking up. Many of us will feel more alert and re-energized after the lazy days of summer, more engaged and inspired to action. And – welcome to many – we may hear … LESS!!!
Some of the sounds of summer are welcome but some of them are just noise. And noise can interefere with our comfort, our conversations, our sleep, our work and play and our peace of mind. Overall summer is a very noisy season. There are at least three reasons for this.
1. It’s a NOISE-MAKING time of year
Summer is the season of road repair, new construction and home renovation in the city: loud machinery, drilling, sawing and banging. Big trucks hauling materials. Of motorized boats and personal watercraft and kids having fun at the lake. Of people on porches and decks, on restaurant patios and the streets and sidewalks, talking and laughing. Of street festivals and concerts and fireworks. So much NOISE!!!
2. Sound TRAVELS in the outdoors
Not only is a lot of sound created by summertime activities, moreof it reaches our ears. Have you ever marveled at how far away you can hear the call of a loon? Soundwaves can travel long distances through calm air over lakes and other open spaces, free of barriers or dissipating factors such as wind. (Unless it DOES encounter something, say a mountain or canyon wall, and bounces back as an echo.)
3. Fewer sound BARRIERS
Of course, after a long Canadian winter, with the arrival of spring and sunshine and warmth, one of the first things we want to do is to throw open our windows, to take in the light and fresh air. And with that, comes all that sound!
Windows are not normally soundproof, but depending on the quality of the glass and number of layers, they will block SOME noise. (Special soundproof windows and other treatments are available to block a lot of noise.) The open window blocks exactly …. no noise. You hear it all.
So summertime often means a lot of outdoor sound is created, travels far, and reaches us through our open windows … it’s “the noisy season”. Purportedly we can thank the noise of summer for the rise of office air conditioning! Employers loved it, because they could close the windows of their workplaces in the summertime. The street noise had been distracting workers from their jobs!
Noise – that is, “unwanted sound”- is not only irritating, it CAN be a serious distraction. Many studies have shown that noise can affect us physically – increasing blood pressure, heart rate and adrenaline. It distracts our attention and interferes with concentration, productivity, learning and memory.
So while we may mourn the shortening daylight and passing of another summer, we can be grateful that quieter times lie ahead.
Although acoustics aren’t at the top of the list of most design project plans or decor considerations, we all immediately – and unhappily – know when we’re in a room that’s too noisy. It could be an office where unwanted sound is literally undermining concentration and memory, and distracting from the work to be done. Or a restaurant that’s just too loud for conversation — too many otherwise-great spots serve too much din with the dinner! Could be a home theatre where the expensive AV equipment isn’t giving the promised quality of sound. In any of these situations and many more, acoustic panels may provide results — and relief!
So, how do you know if a room will benefit from acoustic panels (or other acoustic treatment)? Easy – just run through this list of considerations!
Assess the noise
If you’re working with an existing space, it’s often a simple matter to answer the question: is the sound level inside the room conducive to its intended use and the comfort of the people using it? Is there enough sound for the space to feel “alive”? Or is there so much that the “sound” becomes “noise”? The occupants themselves will not hesitate to tell you the answer!
Even at the planning stage of a new project or renovation, it is fairly easy to forecast the general acoustic impact of the design choices being made. The sound absorption qualities of the planned surface materials can be easily assessed for how they will support the room’s intended use.
Consider the impacts of the noise
Often acoustic treatments are thought of as “nice-to-do” or “add-on options”. Interior designers have told us acoustics are often one of the first items their clients will cut to reduce a project budget.
However, noise levels are MUCH more than a matter of personal preference. Health and well-being, productivity and – in the case of business – profitability, are all affected by noise. Many studies have proven that extensive and/or excessive exposure to noise impacts us physically and in our ability to perform mental tasks. Less scientifically, our personal experience generally confirms the finding, “noise makes us cranky”. And cranky people are not delivering their best, at work or at play!
The International Well Building Institute has published a set of building standards to maintain and enhance occupant health and wellness. Their documentation details how poor acoustics impact our cardiovascular, endocrine and nervous systems!
Good acoustics can be critical to the purpose of and the people in a space. These things are definitely worth a budget allocation.
Consider your options for reducing noise
If you recognize that a room is noisy due to reverberation of the sound created inside it, you may have several options. (If the noise problem is originating outside the room, the issue is soundproofing, not the topic of this post.)
Architectural and decorative surface materials all either reflect or absorb sound to some degree, measured and expressed as their “noise reduction coefficient” or NRC. The NRC for hard surfaces such as drywall, brick, glass, concrete and metal can be as low as zero! These surfaces reflect almost all of the sound waves that reach them, creating a lot of reverberation (i.e., noise!) in a room. The NRC for carpets, lush or plentiful fabrics such as drapes or tablecloths is somewhat higher: they will absorb some sound, and may be a decorating option that will help.
The highest – and best – NRC is obtained in specialized acoustic products. At the construction stage, many projects may be able to incorporate acoustic ceiling tiles or specific flooring materials. But these aren’t appropriate for all types of spaces. And for retrofits, it’s often too late.
This brings us (finally!) to acoustic panels. Acoustic panels – and the related category of acoustic baffles – have extremely high NRC. They can absorb sound to a degree 50 times or more than the rate of most common hard surfaces. (Look for a future post for details on this!) Acoustic panels can be incorporated into original plans and designs and/or added to a finished space. They can be mounted or suspended from ceilings and/or walls. The look can be customized with thousands of potential fabric wraps. And increasingly, they are being offered in more shapes and styles, or with fabrication features that can add much to the visual esthetic of a room.
Acoustic panels can provide the “ahhh” of comfort that makes a room comfortable, beautiful and functional – great to use and enjoy.
Acoustic panels offer many benefits as a component, complement or correction in a design or finished room. Good room acoustics will enhance the space and the users’ experience in it. And good acoustics is more than simply preference, impacting people’s health and well-being. For commercial premises, acoustics can impact a business’ bottom line, enhancing employee productivity and helping attract and retain customers to a comfortable environment.
Acoustics With Design is a Canadian distributor focused on bringing beautiful products to the Canadian acoustics market. This is the first of a series of posts on the subject of acoustic panels, that will address when, where and how acoustic panels can enhance built environments and user experiences.
