S/N and (S+N)/N When measuring signal to noise ratio there are two basic elements to the measurement. One is the noise level and the other is the signal. As a result of the way measurements are made, often the signal measurement also includes noise as well, i.e. it is a signal plus noise measurement.
1 Example: 2  There are three noise sources immediately adjacent to one another, each producing. a sound level of 95 dB. The combined sound level can be found using the table above. The. difference between the first two noise sources is 0 dB, which means the sum will be 95 + 3 = 98. dB.
