Noise is a critical factor affecting room design but, unlike lighting or climate control, it is often overlooked. Effective control of environmental noises and distracting conversations can significantly increase worker productivity while creating privacy from common areas. These noise control methods can take different form and accomplish different types of noise control. One such method, sound masking, is an effective way to eliminate the distractions, as well as privacy concerns, of overheard conversations but how it works, is often misunderstood.
The ABCs of Acoustics
The ABC’s of acoustic design, as architects refer to them, are a variety of elements that can be employed to address noise control and speech privacy. These include solutions that absorb, block, or cover sound. In any given space, the right solution may include involve one method or a hybrid off two or all three. Sound masking systems cover noise and fit into the C category.
We’ve learned that acoustic treatments absorb noise. Sound masking, on the other hand, is the addition of sound. It is an ambient sound, created by digital generators, that are specifically engineered to the frequency of human speech to target conversational noise rendering it unintelligible and therefore, less distracting. Sound masking does not eliminate all noise or cancel sound in an environment; it simply reduces how far conversations can be heard and clearly understood.
Sound Masking: What it is Not!
Sound masking is often referred to as “white noise” but its frequency varies significantly. Unlike white noise’s irritating static, sound masking is engineered to match the comfortable frequency range of the human voice. When designed and installed properly, the “whoosh” of sound masking will fade into the background of a workplace while simultaneously making speech more difficult to hear and, more importantly, to clearly understand.
Sound Masking Success
Implementation of a sound masking system will be far more successful if activated when workers are not present. It’s simple, human nature to hear something when it’s first flipped on and be overly aware of it. Instead, if your staff were to walk in while it’s already on, they would be less likely to notice it, if they noticed it at all. Ongoing, systems can be controlled manually or automatically, set to activate and deactivate based on staff scheduling.
If an environment has widely varying noise levels, an “active volume control” can be added to improve effectiveness. Special microphones (emitters) would be installed to measure the conversational speech levels and adjust the system’s output as the noise levels rise and fall. With the system staying in-sync with the environmental noise, the occupants wouldn’t detect a change.
Often a complement to sound masking, acoustical treatments provide barriers and sound absorption, lessening overall noise levels and reducing reverberation from hard surfaces. What’s the right solution for your space? Call us to request a consultation today.
Custom panels absorb unwanted noise while complementing the room’s decor
Listen! Did you hear that? If you’re home in your media room, are you experiencing the audio as it was intended with clean, crisp speech and striking, directional sound effects? If you’re seated in a cozy restaurant for an intimate, fine-dining experience, are you able to comfortably engage in conversation, or is the space humming with deafening chatter and clanking plates? Sound is a critical factor in how we experience a space, yet it is often completely overlooked in the room’s design.
Laughter and lively conversation create a fun, atmosphere but, if the space is designed with only hard, reflective surfaces, the noise level in the room quickly escalates, reaching an uncomfortable level. In fact, according to a ZAGAT survey, when restaurant-goers were asked what irritated them most about dining out, 25% responded “noise”, a staggering percentage coming in second behind only “service”. A survey by the Action on Hearing Loss found corroborating results; 91% of respondents said that they would not return to a venue where noise levels were too high.
Background music and normal speaking levels are desirable sounds, but noises that bounce off the high ceilings and hard surfaces need to be controlled. That’s the job of acoustical treatment, a thoughtfully engineered and aesthetically designed system of ceiling, wall and floor treatments to absorb unwanted noise and improve sound.
Sound & Surfaces
A sound wave will bounce around a room, reflecting off surfaces until it hits an object that either diffuses or absorbs it. Made of sound-absorbing material like foam or fiberglass, sound absorption products are intended to absorb unwanted noise, such as echo, within a space. Acoustic panels, tiles, ceiling clouds, & ceiling baffles are all sound absorption products that are designed to dampen sound in a properly treated space. An acoustical analysis will determine the treatments required to improve the room’s acoustical properties. Once determined, the design choices are endless with custom fabrics, materials, shapes and placement options that will complement the architecture and décor.
Comforts of home
Uncomfortable noise & distractions aren’t limited to public places. With the trend of many people choosing to work from home, a focus has shifted to controlling sound levels not just in our home theaters, but throughout our homes. Not surprisingly, many newly constructed homes and multi-unit buildings now have noise blocking requirements. For homes that do not offer these initial treatments however, noise control can be combatted with carpeting, area rugs or floating hardwoods, luxurious draperies, plush upholstered furnishings, and, of course, elegant acoustic panels. Panels created for the home can mimic art, featuring works from a favorite artist or perhaps your favorite movie, musician or vacation destination. To open a space, panels can even create faux windows with sceneries and exquisite skylines.
What do you hear?
So, listen. Are you able to have a conversation with the clerk behind the service desk or with your waiter, without shouting? Can you conduct a comfortable video conferencing call from your office without raising your voice above the office chatter and HVAC? Sound is an essential element in the overall experience of a space and the treatments to overcome unwanted noise are extensive and elegant. Are you ready to have a “conversation” about how to address the acoustics in your spaces? Call us today – we’re “listening”!
