Sound masking systems are a common part of today’s interiors, from their original use in offices to relatively newer applications such as hospital patient rooms. Clients primarily include:

Though every sound masking system will introduce a sound into your space, there are substantial differences in terms of how they’re engineered.

The bottom line is that if the sound can’t be properly adjusted to the local acoustical conditions and occupant needs throughout your space, it won't provide the results you're looking for when purchasing this technology: improved speech privacy and acoustic comfort.

The LogiSon sound masking system features a decentralized-networked architecture, often referred to simply by the term networked. Regardless of the type of facility, it fulfills the requirements needed for an effective installation, including:

Small adjustment zones

Adjustment zones are groups of loudspeakers for which you can establish individual volume and frequency settings.

The LogiSon sound masking system can be zoned down to individual loudspeakers. However, zones of two or three loudspeakers are still appropriate and a budget-friendly compromise for open plans. A three-loudspeaker zone typically covers 675 ft2.

Though venturing beyond this size (i.e. to 6 or 8 loudspeakers, or even larger zones) may further reduce costs, it will also introduce ever-escalating tuning and commissioning challenges, decreasing comfort and effectiveness, and restrict future flexibility.

Effective masking sound generation

Rather than broadcasting the same masking sound over a large number of loudspeakers, each small zone within the LogiSon sound masking system has a dedicated masking sound generator, avoiding a problem called phasing or uncontrollable variations in the sound masking levels.

In addition, each generator provides a truly random masking sound (i.e. no repeat cycle). The sound also spans the entire masking spectrum of 100 to 8000 Hz, providing both comfort and effectiveness, and covering a wide range of noises.

Fine volume & frequency control

Regardless of how a system’s loudspeakers are installed (i.e. upward-facing, above a suspended ceiling or downward-facing, cut through a ceiling), the masking sound will be affected as it interacts with other elements of the workplace design.

Therefore, the LogiSon sound masking system provides 100 volume steps in 0.5 dBA increments and 1/3-octave frequency control for each small zone. The masking sound can be tuned to local conditions, ensuring that it’s comfortable and effective across your entire space.

If you couldn’t make such precise changes in specific areas, you’d have to set the masking to a level that’s merely best on average. If you had to increase the volume to improve the system’s effectiveness for the occupants in one area, it would be too loud for others. If you lowered it, you’d sacrifice speech privacy and noise control. This pattern would repeat at unpredictable points across your space.

Suitable loudspeaker driver

The LogiSon sound masking system’s loudspeaker drivers are 4 inches (100 mm) in diameter and rated 25 watts in order to ensure they can generate the low frequencies that are vital to occupant comfort.

Networked control

To ensure maximum acoustic comfort, your sound masking system should be adjusted to suit the unique needs of your facility – and re-adjusted if you renovate, move furniture or personnel.

The LogiSon sound masking system’s settings and zoning can be managed from a centrally-located Network Control Panel or a computer equipped with Acoustic Network Manager Software. Changes can be made in minutes following renovations, moving furniture or personnel. The ease of future reconfiguration reduces lifecycle costs while ensuring peak performance at all times.

Measured results

The acoustic performance of your space before and after the introduction of sound masking can be measured using a sound analyzer.

Therefore, the process should not end as soon as you select your sound masking system. The true gauge of whether it is performing as expected is gained from measurements done after installation and initial tuning. You need to be confident that the volume and spectrum required for speech privacy, noise control and comfort are, indeed, being provided.

We third-octave tune the LogiSon sound masking system using our Target Software, ensuring the system meets the specified masking curve in each measurement location. We also provide you with a report showing the results.
