RNN versus thermal strain acoustic thermometry. Mean absolute error of one RNN method versus TSI—using third-order polynomial fitting). TSI average strain = −0.23 ± 0.05 % to −0.81 ± 0.06 % for ∆T = 2.3 ± 1.1 to 7.71 ± 3.2 °C, with a calculated linear coefficient (λ) = 0.0012 °C−1. Thus, for ∆T > 10 °C, TSI underestimated ΔT by ≈33 %. RNN thermometry average errors E ≈ 2.5 °C for ∆T = 0 to 10 °C and E ≈ 3.8 °C for ∆T = 11 to 30 °C
