The side band noise is similar to white noise (or colored noise) and occupies the whole 25 kHz channel.--- So lets assume that 17 dB D/U is required (U = interference from transmitter on some adjacent channel) - A 100% channel signal and interferer load with 35% MER can be shown to

The achievable accuracy depends on numerous factors (noise level, atmospheric noise, external interference, class of emission, required type of detector, level and frequency stability of the signal, characteristics of the measurement site). Some degree of improvement can be obtained by making continuous field strength recordings.

3.4 table 4 contd. The reason why re-defining of contours is important is that a noise level of, say, 69dB in 1994 does not represent the same level of disturbance or annoyance as a noise level of 69dB now or in 2014. The annoyance is now higher. This was demonstrated by the ANASE study. One of the reasons for this is well recognised.
