available from other manufacturers. It is important that the wall have sound absorption coefficients greater than 0.9 in the 1,000 to 4,000 Hz octave bands. Absorbing panels that have a vinyl protective cover may be reflective at higher frequencies and not suitable for this application. An alternative wall system could be a prefabricated concrete wall such as Verti-Crete or a fence having at least STC 20. This option will require sound absorbing panels to be attached to the wall or fence. Noise Barriers makes panels under the name QuietPerf that work for pickleball (see noisebarriers.com). A two inch panel is sufficient. Coverage must be at least 90% of the interior wall surface. 6.3 Installation Cost Estimates NOTE: These cost estimates do not include tax, general contractor mark up, insurance, permit fees, design and engineering fees, drawing fees, etc. All pricing is approximate and intended only for comparative analysis of differing noise control fencing systems and is subject to verification or modification by appropriate contractors.
