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
