Question #10494

If a sound pressure is measured at 2Nm^-2, calculate this in dB(SPL)

Expert's answer

If a sound pressure is measured at 2Nm^-2, calculate this in

dB(SPL)

Reference sound pressure p0 = 20 μPa = 2 × 10-5 Pa ≡ 0 dB

2 Pa = 2

/ 0.02 = approx. 100 dB.

dB(SPL)

Reference sound pressure p0 = 20 μPa = 2 × 10-5 Pa ≡ 0 dB

2 Pa = 2

/ 0.02 = approx. 100 dB.
