The CrossWays™ Sound Masking System must provide the following:

  • Direct field speaker
  • All masking/paging units must be UL Listed for air handling space.
  • System must confirm following ANSI standards: ANSI S1.4, ANSI S1.6, and ANSI S1.11
  • System must meet ASTM 1130-02, ASTM E1573-02, ASTM E 1374-93, and ASTM E 1041-85 standards.
  • The Sound Masking system must use a unique integrated sound masking, music and paging system that uses infrared remote controls.
  • Volume increments for paging and music MUST be in ½ dB steps never to exceed more than 1dB steps as measured 1m from the speaker.
  • The sound masking source must produce 20Hz through 20,000Hz.
  • The masking must be random.
  • The masking volume shall be adjustable via digital means for ½ dB steps for a range of 30-78 dBA as measured 1m from the center of the speaker.
  • Sound masking system must be able to provide muting capabilities.
  • Spatial uniformity of sound must be no more than ±½ dBA.
  • In open areas and larger enclosed spaces, the overall sound level produced should have spatial uniformity of no more than ±½ dB between any two sound generating units.
  • System must provide two sizes of speaker: 4 ½" and 8".
  • 4 ½" speaker housing must be produced from recycled ABS material. 8" speaker housings/enclosures must be damped to avoid undesirable resonance.
  • System shall be designed so that individual speaker or component failure will have no impact on the balance of the system
  • Generation and integration of multiple random sound masking sources and by using E-sound® technology equates to the best sound and effective sound masking.
  • Sound masking equipment must be comprised of at least 50% recycled Aluminum content.
  • A 10 year full warranty from the manufacturer must be provided for all sound masking equipment.
  • The system must be manufactured in the USA.
