Quiet Parks International (QPI) is a non-profit committed to the preservation of quiet for the benefit of all life. It was formerly known as the One Square Inch of Silence Foundation (OSI).

In 2005, OSI was heralded as a naturally silent national treasure by acoustic ecologist Gordon Hempton, Founding Member of Quiet Parks International, who deemed it the least noise-polluted spot in the lower 48 states.

Quiet is Scarce

QPI recognizes the immediate need for identifying and protecting these endangered locations due to the realization that quiet places are quickly becoming extinct.


Noise is Harmful

Noise pollution causes cardiovascular disease, hypertension, sleep disturbance, annoyance, cognitive impairment, hearing impairment and tinnitus, and reduces quality of life, well being and mental health.

Our Mission

Quiet Parks International is currently creating a set of classifications, standards, testing methods, and management guidelines for the certification of the world’s pristine and endangered quiet places. Quiet Parks International has established the world’s first Wilderness Quiet Park and developed a list of over 262 potential sites around the globe that should be certified and preserved.


Our Vision

Quiet Parks International provides assistance with research, education, advocacy and conservation efforts to protect quiet for future generations.
