The Noise Center
Hear for the Future® The Center for Hearing and Communication is proud to offer the Noise Center as a public service for people seeking information about the dangers of noise exposure and the steps they can take to promote a safer and quieter world. Exposure to noise is the leading cause of hearing loss—not age. -
Common environmental noise levels
How loud is too loud? Continued exposure to noise above 85 dBA (adjusted decibels) over time will cause hearing loss. The volume (dBA) and the length of exposure to the sound will tell you how harmful the noise is. In general, the louder the noise, the less time required before hearing loss will occur. According -
The impact of noise on childhood cognitive development
Poor classroom acoustics: The invisible reason Johnny can’t read. Poor classroom acoustics create a negative learning environment for many students, especially those with hearing or learning difficulties. According to a report by David Lubman (“America’s Need for Standards and Guidelines to Ensure Satisfactory Classroom Acoustics”) “acoustical conditions in many classrooms are unsuitable for such tasks -
Congressional Quiet Skies Caucus Letter To FAA Administrator Steve Dickson re DNL65
Currently, FAA law has extremely complicated rules for establishing a noise boundary around airports. (A noise boundary is a geographic area inside which there is a certain acceptable noise level.) This is referred to as the DNL65. and it has several major flaws. The FAA Reauthorization Act Of 2018 attempted to address these flaws in several ways. This letter, from a caucus of Congressmen engaged on airport community issues complains to the Administrator that the spirit of the law is not being adhered to and demands that he make attempts to put his agency into compliance. The language is fairly technical, however there are a couple of basic points they raise: First, that the noise boundary be determined by actual noise measurements (currently the noise boundaries are 'modeled' and those calculations often do not reflect in any way the lived experience for residents.) Second, that the 'acceptable' noise level of sixty five decibels (hence DNL65) has been determined to be far too high to conform with current understandings of healthy living. -
New aircraft-noise rule would do little to quiet the skies: government report
By Jon Hemmerdinger 24 August 2020 A ban on aircraft that do not meet new noise standards would do little to reduce overall aircraft noise and would impose costly requirements on airlines and aerospace manufacturers. That is according to a 20 August report from the US Government Accountability Office into the likely impact of a -
2020-06-11SHB1847 – Aircraft Noise Abatement Various Provisions
Washington State legislation that amends RCW 53.54.010, 53.54.020, and 53.54.030 to expand aircraft noise abatement programs. The bill reduces the threshold for port districts to undertake noise abatement programs from twenty to nine hundred scheduled jet aircraft flights per day and modifies the boundaries of impacted areas eligible for various remedial programs including property acquisition, -

2020-01-10Adverse Cardiovascular Effects of Traffic Noise with a Focus on Nighttime Noise and the New WHO Noise Guidelines
A comprehensive review examining the cardiovascular health impacts of traffic noise exposure, with particular emphasis on nighttime noise effects. The study discusses WHO guidelines, mechanistic pathways involving oxidative stress and vascular dysfunction, and epidemiological evidence linking noise exposure to heart disease, stroke, and other cardiometabolic conditions.
