Adaptive Volume Based on Office Noise Levels

Your office space is a dynamic environment where ambient noise levels and the amount of distractions vary a great deal depending on the schedule and activities underway. To be truly efficient at all times, sound masking must continuously adapt to the ever-changing office soundscape: it must subtly increase during busier, noisier periods of the day, then get back down to its minimum effective volume level as the office gets quieter.

Sound Masking That's Never Too Loud, Never Too Weak, Always Efficient

It's the mid-morning rush at work and the office is buzzing with activity, conversations and potential distractions? The sound masking volume gently goes up. That mid-morning rush ends and the office space goes practically silent? The sound masking volume decreases back to where it was before the rush. And it'll continuously move up and down like that: up to its maximum allowed level, down to its minimum effective level, and anywhere in between, in reaction to changes in office activity level over time. Simple enough? Our sound masking system is the only one in the world that makes this possible.

Self-adjusting sound masking volume based on office noise levels

How Does Adaptive Volume Work?

Adaptive volume makes use of ceiling-mounted noise sensors and the advanced signal-processing technology embedded in our controllers to automatically adjust the sound masking volume up or down based on how loud or quiet the office gets throughout the day. Auto volume adjustments are virtually unnoticeable and only occur for sustained variations in office noise levels—never for sudden noise or short activity spikes.

What About Timer-Based Volume Adjustments?

While adaptive volume makes sense in most office sound masking applications, our system still includes a timer function just like the older sound masking technologies out there. It lets you preschedule exactly when and by how much the sound masking volume should increase or decrease for each day of the week, for each independent office zone.

Timer-Based or Adaptive Sound Masking: What's Best for Acoustic Privacy and Comfort?

It's scientifically proven that allowing the sound masking volume to vary continuously based on office noise levels improves the occupant experience more than sound masking with a preset timer function. At the 2017 NoiseCon Conference held by the Institute of Noise Control Engineering of the USA, we've presented a research paper to demonstrate how sound masking systems with self-adjusting volume consistently achieved the same levels of speech privacy as older systems relying on a 45 dBA volume timer function. But that was just the first half of the study.

When it came to surveying the acoustic comfort of office occupants, the timer-based sound masking systems were simply no match for the newer systems with adaptive volume. In periods of moderate office activity, acoustic comfort improved 50% in comparison to timer-based systems.

What's more, setting the maximum sound masking level to 48 dBA (CNRC-recommended upper limit) instead of 45 dBA improved speech privacy by 15% in comparison to timer-based systems, without any impact on perceived acoustic comfort. In other words, the average office worker didn't feel a difference between 45 dBA and 48 dBA sound masking, but slighlty louder sound masking made overhearing conversations and eavesdropping 15% less likely.

Timer-Based Sound Masking

Prescheduled Volume Adjustments

  • At what exact times in the day should the sound masking volume get louder and back to its regular, minimum level? When are the busiest and quietest periods in the office, in terms of employee interactions?
  • Does this schedule apply to any day of the week? What about weekends?
  • Does it apply to the entire office space or should certain work areas run a different volume schedule at certain times, on certain days?
  • How smooth should the volume level transitions be? Would office occupants like to experience a 10 dB variation in sound masking volume within a mere few seconds? Take our word for it: they won't.
  • Timer-based volume control wrongly assumes that office activity levels and intensity of conversations are always on schedule. In today's highly flexible workspace, it's rarely true. Noisy distractions can arise anytime and so does the need for more speech privacy.
  • Timer-based sound masking was a thing 20 years ago. Today, the only valid reason for preferring it over adaptive sound masking is running an old-fashioned system without adaptive volume control. There, we said it.

Adaptive Sound Masking

Automatic Volume Adjustments

  • The sound masking volume is always as loud or quiet as it needs to be, and always within recommended standards.
  • No need to figure out in advance how busy or calm the office space will be at any given hour, on any given day. The system measures office noise levels in real-time and adjusts itself without anyone noticing.
  • It's the active control sensors that do all the work: they continuously measure the noise levels across the room and tell the controllers to increase or decrease the sound masking volume in order to ensure optimal acoustic comfort and speech privacy at all times.
  • You're always in control as volume reactivity (how sensors perceive variations in office noise), adjustment rates, high limits, and low limits are programmable separately, for each sound masking/paging zone.
  • Why one of our most notable competitors, Biamp's Cambridge Sound Management, relentlessly speaks badly of our adaptive sound masking technology is beyond us. What is it about having made sound masking more effective and simpler for all that Biamp doesn't like?

Automatic Sound Masking Equalization Process

The greatest challenge in any sound masking project? To generate the recommended ideal sound masking spectrum while taking into consideration the space's unique design attributes. Room size, ceiling type, acoustic tiles, wall finishes, and office furniture all have an impact on how efficient sound masking is at drowning out distractions and improving acoustic privacy. If the masking system is not perfectly calibrated according to the acoustic response properties that are unique to the area it covers, it'll be ineffective at best and irritating at worst.

The Perfect Sound Masking Spectrum Anytime, Anywhere

Our system's automatic equalization process allows it to adapt itself to an endless array of office environments. It analyzes the acoustic response and the background noise in the space covered and uses this data to figure out the spectrum needed to generate a soft, neutral and pleasant masking sound. So whichever sound masking spectrum is right for your space and the acoustic comfort of occupants, whether it's our default CNRC-recommended spectrum or a custom spectrum specified by your own acoustician, our system's automatic equalization process continuously ensures that this ideal spectrum is exactly what comes out of the sound masking loudspeakers in the end.

Calibrating Entire Sound Masking Systems Takes Minutes, Not Hours

Did we say minutes? Actually, our patented technology makes it possible to calibrate individual sound masking zones in less than a minute, with equalization done in both 1/3 octave and 340 narrow band spectra. The process is fast, very precise, and guarantees a remarkably smooth sound masking output throughout the covered area.

The quality of calibration is assessed in real-time by our system’s integrated frequency analyser. At a glance, the person running the initial system calibration gets a clear indication as to whether the sound masking signal generated is consistent with the desired spectrum.

Soft dB's networked sound masking system and installation plan met our challenging office space requirements. We're very pleased with how our system is working and making a positive impact on the quality of our work environment.

What Do Sound Masking Systems Consist Of?

All sound masking systems have the same purpose: artificially increasing the ambient background sound level of a space just enough to even out its sonic landscape, eliminate awkward pin-drop silent moments, and decrease speech perception within and between different office areas. This is achieved by spreading a specially engineered broadband sound—similar to the sound of air flowing in HVAC systems, but smoother and much more consistent—across the space through a network of loudspeakers strategically positioned to ensure seamless, uniform coverage.

Multizone Controllers

Controllers are the brains of our sound masking system. They generate the perfect broadband sound signal and ensure that each group of speakers emits just the right amount of masking sound in the select area it covers.
