3. Comments and Recommendations:
If you are required to address the noise nuisance that the Condominium residents
complain about, we recommend a minimum of 9 dB A noise reduction (NR) at the noise
source, for worst case scenario, which is 68 dB A at the north property line of the water
treatment plant facilities. To accomplish this goal, the following acoustical l~t+dware must be
installed on the noise source:
3.] Tinned Resonant Absorbent (TRA) P$ncls: Apply 14 TRA panels 1 1/4"x4'x10'
over the existing chain link fence, around the cooling towers, in front of the air supply
louver in the air blower housing and reinforce the existing noise application at the pump
room louvers facing the Condominium property. The budget price for this application is
S 18,71H1.0E1 including materials, manufacturing and installation.
A detailed quote and conceptual drawings for the noise reduction hardware here described
will be submitted to your attention upon request
If you have any questions or comments about thisreport or shouldyou requireadditional
assistance in this project, please call us at your convenience.
Best regards,
