During a ferry ride to Sausalito, Dr. Daniel Fink noted a rare sign requiring ear protection near the engine room—a reminder that while workplace noise has safety limits, no standards exist for public noise exposure.

International Noise Awareness Day (INAD), founded in 1996 by Nancy Nadler and others, aims to raise awareness about the harmful effects of noise on hearing, health, and quality of life. Celebrated globally, including in the U.S. and South Africa, INAD marks its 30th year on April 30. The Quiet Coalition and Quiet Communities, Inc. encourage efforts toward a quieter, healthier world.
