1/3 Octave Filter Summation

For this test, sine waves from 20 Hz to 20 kHz are measured with the Concerto system. For each sine

wave the summation of the 1/3 octave filters is computed to form the following curves. The sine

waves are electrical signals at 1 VRMS. The next figures present the results for both input range.
