Transmission Loss (TL) values were calculated at these additional test frequencies. Although the measurements were made in accordance with the procedures described in ASTM E90-99, they do not qualify as part of the standard. Since the results for these low frequencies are representative of the test environment only, they are unofficial and intended for research and development guidelines rather than for commercial purposes.
