On various Verizon and AT&T sites throughout southern California, HELIX Environmental Planning provides noise control planning and noise engineering for cellular installation plans. Specialty planning for some of these sites has included the complete conceptual design for a fully enclosed site. Examples of this include the Carmel Country Club Verizon Site in the community of Carmel Valley and the Beagle Verizon Site in the community of Linda Vista in San Diego. For these projects, HELIX’s acoustical specialist developed a design that used silencers, acoustical louvers, and forced ventilation fans to minimize noise levels from the generator and air conditioning systems to be in compliance with residential noise limits.
