The annual average sound level
of road traffic noise estimated from the speed-flow diagram.
The study's main focus will be the average noise levels, also known as day-night average sound level
contours, produced by aircraft using the base, said Cory Walters, 434th CES biological scientist.
Under the bill to be known as the "Aviation Noise Limit Act," the Air Transportation Office of the Department of Transportation and Communications is directed to develop a medium-term plan to reduce by at least 75 percent the number of individuals residing in residential areas in the vicinity of an airport who are exposed to a yearly day-night average sound level
of sixty decibels or above.
A study published yesterday found the average sound level
in the city's boozers is 92 decibels, more than the safe level of 85 decibels.
Equivalent noise level is the energy average sound level
spriememenej during the measurement interval.
a dose reading where a value of 100% is the maximum allowable exposure to accumulated continuous noise (according to OSHA, a 100% dose occurs for an average sound level
of 90 dBA over an 8-hour period);
The average sound level
experienced by participants during the almost 2-hour exposure was 100.
Most FERC-regulated facilities must comply with the maximum facility sound level contribution of 55 dBA Ldn at all NSAs, which is measured using EPA's day-night energy average sound level
The FAA regulates noise according to a value called the day-night average sound level
, abbreviated as DNL.
In the study, the average sound level
of personal stereos was 95-96 decibels.
The program covers homes in areas near LAX that register an airport-related sound level of 65 decibels or higher and aims to reduce the average sound level
inside targeted homes to 45 decibels or lower.
Average sound level
measurements (dBA) of a vuvuzela with the SANS2 recommendations for duration of sound exposure allowed at specific intensities (every 3 dB increase halves the allowed exposure time, starting at 8 hours for 85 dBA).
