The May 15 Health & Science article “Hearing complaints, cities and states crack down on noise” claimed that the Pentagon has agreed to study helicopter noise and ways to minimize its effects in the D.C. area. In 2016, at the urging of Rep. Don Beyer (D-Va.), whose district is hammered every day by the roughly 145 military helicopters routinely ignoring Fly Friendly guidelines, Congress required the Defense Department and the Federal Aviation Administration to produce a joint report on helicopter noise in the national capital region by March 2017.

That never happened. 

It took more than a year, and a $29,000 contract, before the Pentagon released a short report that merely recommended creating a noise inquiry website and establishing a noise-abatement working group. 

The eight-page report, released in February,  failed to do a noise study or to explain why the FAA stopped tracking helicopter flights over Northern Virginia in the summer of 2017. Before that, it was possible to track and identify the helicopters — and the alarmingly low altitudes they flew over our homes. For nearly a year I had tracked and filed complaints about dozens of military helicopters flying well under 500 feet over my home.

Mr. Beyer asked Defense Secretary Jim Mattis for the department’s help in fixing a problem that the military created and cooperation in reducing helicopter noise in the region. More than two months later, Mr. Mattis has yet to reply to the congressman’s letter.
