Kryter, "The Meaning and Measurement of Perceived Noise Level," Noise Control 6:5, Sept.-Oct., 1960, pp. Contours of perceived noisiness (from ISO recommendation R507, 1966). The exact method of calculating noys is analogous to that of loudness index summation described under LOUDNESS and Appendix F. Compare: COMMUNITY NOISE EQUIVALENT LEVEL, NOISE LEVEL, NOISE POLLUTION LEVEL, SOUND LEVEL. See also: EFFECTIVE PERCEIVED NOISE LEVEL, NOISE AND NUMBER INDEX, NOISE EXPOSURE FORECAST. The tendency at present is for many airports 'theoretically' to accept 110-112 PNdB for daytime flights and 100 PNdB for night flights but these limits are more generally theoretical than actual, and they are still very high. In converting decibels on the A WEIGHTING NETWORK to PNdB, a very rough method is to add 12 dB thus 100 dBA = 112 PNdB. The DECIBEL scale at the left of the graph is for FLAT response. The equation expressing this relationship (analogous to the relation between the PHON and SONE ) is: PNdB = 40 + 10 log 2 (noy) From the chart at the right of the graph, the noy scale can be converted into PNdB. Using EQUAL LOUDNESS CONTOURS, Kryter converted the decibel scale into a series of increments, to which he gave the unit of the NOY. The scale has been adopted by the International Standards Organization for international use.Īs jet engines were perceived to be noisier than propeller aircraft because of differences in the SPECTRUM of the noise they produce, the method followed a similar approach to LOUDNESS summation of COMPLEX TONE s. Kryter in 1959 to attempt to measure the perceived noisiness of jet aircraft by observers on the ground. Perceived_Noise_Level PERCEIVED NOISE LEVEL (PNL)Ī scale developed originally by K.D.
