Today's office designs are going more "open" these days - and with good reason. Lower costs, increased collaboration opportunity, and similar factors are coming into play for architects and office designers, especially in areas meant for hosting startup companies. However, with these designs comes a common issue - the emergence of lots of speech amongst the workers.
This isn't a bad thing, right? You want a bustling workplace - it means business is good, right? Wrong.
Did you know that according to a 2014 Steelcase/Ipsos study, employees can lose up to 86 minutes a day in lost productivity due to distractions? Did you know that the same surveys show that over 60% or workers cite lack of speech privacy as their main distraction? It's simple - people won't be productive workers if they get distracted, companies run the risk of unsecured info reaching the wrong ears, and so on.
Enter sound masking - an ambient background pink noise introduced into an office space. It's specifically tuned to match frequencies of human speech, generated at a level intended to make speech levels less intelligible. When sound masking is present, other workers' conversations are notably less invasive to an employee's work, providing better efficiency and comfort in the office, increasing overall productivity. Whether the office's ambient levels are pin-drop quiet, or full of loud sounds, properly installed sound masking can make nearly any workplace a comfortable environment for all.
How does sound masking work?
Sound masking systems generally work by emitting pink noise into a particular space, either from the ceiling or (in special cases) the floor. The sound's frequencies are then specifically tuned (based on a number of various factors) to match specific patterns of sound travel and speech levels in the space. Depending on the system this can either be done on the front panel of a control unit or via a software application. The signal is then distributed through a series of emitters, which are in most cases a type of loudspeaker that mounts in a drop ceiling. The system is then volume-adjusted to match the measured projected ambient sound levels in the room.
What does it do?
It reduces the distance between talkers and listeners in which conversations between talkers and listeners are intelligible and easily overheard. If someone standing a distance away from you is talking, the masking signal "blurs" the consonants of the speech, making your ears less likely to "latch on" to the conversation (distracting you from your work).
