Economic Benefit of Noise Control Worksheet This worksheet is intended to support the purchaser's efforts to advocate a low-noise purchase. It estimates the long-term economic cost of noise exposure and thereby is - [Applicability of the BuyQuietRoadmap](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/applicability/) - The BuyQuietRoadmap is focused entirely on hearing loss prevention and does not specifically address other important noise exposure issues such as speech intelligibility and work environment comfort that are often associated with moderate- or lower-level noise sources. A comprehensive approach to noise exposure management will consider these lower and moderate level noise issues as well - [Criterion Adjustment Authorization Form](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/forms-worksheets/criterion-adjustment-authorization-form/) - Criterion Adjustment Authorization Form (127 KB) Use this document whenever it is necessary to increase the noise emission criterion beyond the baseline values. Note: If the baseline criterion is expressed as a sound power level (PWL), a yellow box appears for the user to enter the criterion value. If the baseline criterion is 80 dBA - [Field Verification Authorization Form](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/forms-worksheets/field-verification-authorization-form/) - Field Verification Authorization Form (76 KB) Use this document to describe the results obtained and/or decisions made at the field verification stage affecting acceptance of the equipment. - [Economic Benefit of Noise Control Worksheet](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/forms-worksheets/economic-benefit-of-noise-control/) - Long-term Economic Benefit of Noise Control (183 KB) This worksheet is intended to support efforts to advocate a low-noise purchase. The spreadsheet performs computations to estimate the net benefit of current noise control expenditures versus the anticipated cost of noise induced hearing loss at a later date. The user enters or selects the current TWA - [Community Noise Check Worksheet](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/forms-worksheets/community-noise-check/) - Community Noise Check (72 KB) Use this worksheet to estimate potential sound levels in the community due to outdoor equipment. Using the Community Noise Check Worksheet Besides the effect of noise emission on personnel within the facility, the impact of noise on neighbors and/or nearby communities should also be considered. Use the community noise check - [Equipment Test Standards](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/verify-noise-emission/equipment-test-standards/) - Detailed test standards have been written for many types of equipment. These should be used whenever possible because of the considerable forethought related to testing and operational conditions that has been invested in the them. If you don't find the type of equipment you are purchasing listed below, use the Elementary Equipment Sound-Level Verification Test - [Select Baseline Criterion](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/select-noise-emission-criterion/select-baseline-criterion/) - Equipment Covered by the EU Machinery Directive For equipment covered by the European Union's Machinery Directive (Updated) , you can use the specified sound power level as a baseline criterion. The EU Machinery Directive specifies sound power level noise emission limits for equipment manufactured or sold in the EU. These limits are considered to represent - [Lowest Price Technically Acceptable Source Selection Process](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/determine-procurement-classification/lowest-price/) - In the context of the Buy-Quiet Process Roadmap, the Lowest Price Technically Acceptable option requires the Contracting Officer to select the lowest priced product from among three that meet or exceed the technical requirements. The Requestor provides the Contracting Officer with three acceptable sources, and the Contracting Officer makes the selection and awards a contract. - [GSA Schedule Purchase](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/determine-procurement-classification/gsa-schedule-purchase/) - In the context of the Buy-Quiet Process Roadmap, a GSA Schedule purchase may be made when a product for which product-specific noise emission data meets the baseline noise emission criterion is available on the GSA Schedule. The Requestor works with the Contracting Officer, who will place the order. GSA purchases are similar to micropurchases in - [Determine Simplest Allowable Procurement Strategy](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/determine-procurement-classification/) - A low-noise procurement process merges the consideration of product noise emission and noise exposure issues with the NASA procurement process. Once you have researched the availability of low-noise products that meet your requirements and have selected an appropriate noise emission criterion, the next step is to find the simplest allowable procurement strategy that will accommodate - [Site Map](https://buyquietroadmap.com/site-map/) - [BuyQuietRoadmap](https://buyquietroadmap.com/buy-quiet-purchasing/buy-quiet-process-roadmap/) - The Buy-Quiet process helps you develop requirements for low-noise equipment that is efficient, cost-effective, and, most importantly, safe for the people who work with and around it. Like most processes, this one can get pretty long and complicated, so use this roadmap to find your way through it!
