Current Projects

QPI is developing the Research Foundation for better understanding of the effects of quiet and noise pollution on all life. Our Team consists of scientists, social scientists, acoustic ecologists, musicologists, analysts, research librarians, and professionals who are part of a multi-disciplinary research community.


Research Database

QPI research librarians are partnering with the QPI Team on an ambitious project to index all the world’s research literature on the effects of quiet and noise pollution. The purpose is to create a publicly available search tool that will search all existing research literature.  This will be available free of charge for use by researchers, educators, professionals, journalists, and enthusiasts.

This project launched April 2019 and will be an ongoing iterative effort that will continue into the future. As we learn more about the research landscape from our partners, QPI will expand the database.


2019 Interim Standards

The 2019 Interim Standards for Parks and Reserves is the work of a multi-disciplinary Standards Committee representing a variety of backgrounds and methods. The members convened in first quarter of 2019 to develop the Standards through a collaborative review process.


Site Selection for Certification

QPI instituted a project developing a six-step process to remotely identify candidate parks and reserves for certification. Following this method, researchers identified 262 highest priority locations for certification that are displayed in the map of Potential Quiet Parks. Further methodological review, analysis, and consultation will continue to refine this process in support of locating additional candidates for certification.

Sample data sources used include:


Data Management and Analysis

The QPI Standards define the data set collected onsite by QPI field technicians for certification assessment using a GPS, pair of high sensitivity low-noise omnidirectional microphones, digital recorder, and sound level meter. Additional qualitative information including land history and use is gathered through conversations with land managers.

QPI data librarians will institute a Data Management Plan to collect, normalize, and analyze QPI Certification Standards data in compliance with the standards created by the National Science Foundation.

The purpose of the Data Management Plan is to certify and classify qualifying parks and reserves, and build a repository of data to perform a year-on-year analysis of the global “State of Quiet” through acoustic measurements collected over time.
