    2. Mounted mechanically on a wood batten support frame, with the gap closed or filled with a substrate of at least class A2 - s1, d0 with minimum density of 10 kg/m3 or filled with a substrate of cellulose insulation material of at least class E and with or without a vapour barrier behind.
    3. Note 2: 6A001.a.1.c. does not control electronic sources which direct the sound vertically only, or mechanical (e.g., air gun or vapour-shock gun) or chemical (e.g., explosive) sources. 1. An instantaneous radiated 'acoustic power density' exceeding 0,01 mW/mm2/Hz for devices operating at frequencies below 10 kHz; 2. A continuously radiated 'acoustic power density' exceeding 0,001 mW/mm2/Hz for devices operating at frequencies below 10 kHz; or Technical Note: 'Acoustic power density' is obtained by dividing the output acoustic power by the product of the area of the radiating surface and the frequency of operation. 3. Side-lobe suppression exceeding 22 dB;
