40、raft or equipment, and wind effects.4 Measurement quantities4.1 Frequency weighting A shall be used for all measurements.4.2 Care should be taken to avoid any influence on the result from unwanted sound signals, for example noisefrom wind on the microphone of the measuring equipment, electrical inte
41、rference, or extraneous sound sources notunder consideration.4.3 The quantities to be determined at all microphone positions in acceptance and monitoring tests are theA-weighted sound exposure level, LAE, received from the operation of vessel and the maximum AS-weighted soundpressure level, LpASmax,
42、 both expressed in decibels.4.4 If, in addition to the sound exposure level, spectral analysis in acceptance tests or determination of somespecial acoustical characteristics of vessels is needed, the quantities to be measured are the unweighted orC-frequency weighted, octave-band or one-third-octave
43、-band S-time weighted sound pressure levels in decibels atthe time of maximum sound pressure, or the unweighted or C-frequency weighted, octave-band or one-third-octave-band sound exposure levels in decibels.4.5 When measurements are made at some distance from the source, the levels observed may be
44、considerablyaffected by the weather conditions. For example, the attenuation of sound due to air absorption is affected by thetemperature and humidity of the air. In addition the refraction of sound waves due to wind and temperaturegradients will affect the levels received at a particular position.
45、It is recommended that measurements taken inextreme or atypical conditions be avoided. If possible, a value obtained under typical climatic conditions, and anindication of the range of values obtained under other climatic conditions, should be included in the test report.4.6 For steady-state noise,
46、as that from a stationary ships engine, the quantity to be measured is the time-averaged A-weighted sound pressure level, LpAeq.5 Measurement uncertaintyTable 1 lists the likely sources of uncertainty and estimates of the standard deviation associated with each basedon experience. These sources of u
47、ncertainty are considered to be independent for each measurement type.Therefore, the estimated total standard uncertainty is given by the square root of the sum of the squares of theindividual standard deviations contained in Table 1.BS EN ISO 2922:2000+A1:2013 EN ISO 2922:2000+A1:2013 (E)3 Table 1
