11.16 tone-corrected perceived noise level. Perceived noise level obtained by adding an adjustment that is related to the degree of irregularity that may occur among contiguous one-third octave band sound pressure levels of an aircraft noise. Unit, decibel...
11.15 noy. Unit of perceived noisiness, equal to the perceived noisiness of a one-third octave band of noise centered on 1 kHz and having an A-weighted sound pressure level of 40...
11.14 perceived noisiness; noisiness. Prescribed function of sound pressure levels in the 24 one-third octave bands with nominal mid-band frequencies from 50 Hz to 10 kHz that is used in the calculation of perceived noise level. Unit, noy; abbreviation, n....
