    "text": "sigma1 makes the high modes decay faster, in proportion to the square of their wavenumber; it stands mainly for radiation into the air. Too little and the highs ring like a cymbal; too much and the sheet sounds dull. At the lowest value here the band above 2 kHz decays about as slowly as the low modes; at the highest it sits more than 50 dB below the 100 to 500 Hz band.",
