Noise level means the “A” weighted sound pressure level in decibels obtained by using a Sound Level Meter at slow response with a reference pressure of twenty (20) micropascals. The unit of measurement shall be designated as “dBA.”
Noise level means the reading on an integrating impulse sound level meter taken at a measuring point in the presence of any alleged disturbing noise at the end of a total period of at least 10 minutes after such meter was put into operation, and, if the alleged disturbing noise has a clearly discernible pitch, for example, a whistle, buzz, drone or music;
Noise level means “A” weighted sound pressure level in decibels dB(A) as defined and tabulated in the British Standards specification number BS EN 60651; 1994 Specifications for Sound Level Meters;
Examples of Noise level in a sentence
Assumptions: ⮚ Noise level measurements will be re-conducted to calibration the FHWA TNM version 2.5.
More Definitions of Noise level
Noise level means the “A” weighted sound pressure level in decibels obtained by using a sound level meter at slow response with a reference pressure of twenty (20) micronewtons per square meter. The unit of measurement shall be designated as dBa.
Noise level means the amplitude of sound pressure referenced to twenty (20) micropascals, measured in decibels, using the A-weighting network (for the purposes of this chapter).
Noise level means the A‑weighted sound pressure level in decibels as read from approved sound measurement equipment;
Noise level means the level of noise, measured in decibels or other suitable units; and
Noise level means weighted sound pressure level measured by use of a metering characteristic with an "A" frequency weighting network and reported as dBA.
Noise level means the maximum continuous sound level or repetitive peak sound level, produced by a source or group of sources as measured with a precision sound level meter. In order to measure a noise level, the controls of the precision sound level meter should be arranged to the setting appropriate to the type of noise being measured.
Noise level means “A” weighted sound pressure level in decibels dB(A) as defined and tabulated in the British Standards specification number EN 60651:1994;
