Commercial Office Sound Masking Systems are an ideal solution when speech privacy is needed and sound isolation options are limited. This is often the case in Open Offices, Commercial Spaces with ACT Ceilings, or Coworking Locations.
Sound Masking is not an active noise cancellation technology. Rather, it provides a background ambient noise that increases the noise level across the space with a blended white noise and pink noise spectrum. By doing so, it makes other conversations and noises less audible to the listeners. This decreases distractions and frustration on behalf of workers that cannot focus due to nearby noise sources.
Sound Masking is most effective when installed on the “receiver” side. If there is loud mechanical or HVAC equipment, or a human-based noise source, the sound masking should go on the side of the partition where the listener is inconvenienced by the noise.
Sound Masking Overview:
- Each Unit Covers Approximately 200 Square Feet
- Low Voltage (5V) & Energy Efficient
- Expert Support for System Design and On-Site Balancing & Tuning
- Tuning to +/- 0.5 dB. Done in field based on plenum to wall heights.
- Standard Sound Masking Spectra, as well as White Noise & Pink Noise Capabilities
- Standard Add-Ons: Remote Control for Volume Adjustments
- Optional Add-Ons: Central Control for Ramp-Ups and Daily Fluctuations
- ASTM standards for speech privacy as well as spatial and temporal uniformity of sound. UL listed for use in the plenum
