Conformance Notes

¶ 11.8: Signal level > 5 dB above background — False at 1250 Hz (signal-to-noise ratio < 6 dB; SPL only provides estimate of lower limit).
¶ 10.4.4: Receiver room volume met minimum — Confirmed.
¶ 10.4.5: Receiver room absorption met preferred value — Confirmed.

* 1250 Hz: signal-to-noise ratio < 6 dB — value is a lower-limit estimate only.

Darker bars (100–315 Hz) indicate the low-frequency range where thin underlayments perform weakest.

  3. Concrete Structural Floor · Thickness unknown
  4. Suspended Gypsum Board Ceiling · Thickness and construction unknown

Conformance Notes

¶ 11.8: Signal level > 5 dB above background — Confirmed.
¶ 10.4.4: Receiver room volume met minimum — False. Receiver room volume (660 cu. ft.) is less than the required 1,412 cu. ft. (40 cu. meters). Result may not be reliable.
¶ 10.4.5: Receiver room absorption met preferred value — Confirmed.

This test does not conform fully to the requirements of ASTM E336-25. The receiver room volume is too low for a reliable measurement. The AIIC 51 result should be interpreted with caution.
